How well will an 80-meter resonator work without a mast on mobile? I have a Diamond lift mount, mounted 15" below the roof, and using Hamsticks am getting surprisingly good results on 20M, and good results on 40M. My 80M hamstick isn't getting good results, not surprisingly, despite a 1:1 SWR. If I use only the 80M Hustler resonator as you've described, or lengthen it by adding a spring and 9" mast that I have on hand, will I get a workable efficiency? I have a bug catcher base load coil I can add as well.
For as long as the Church controlled the insane, they endured dreadful torments. They were imprisoned, chained to a wall (or if they were lucky to a bed), flogged, starved, insulted, tortured, immersed in iced water and otherwise brutalised. It also seems safe to assume that sexual abuse would have been commonplace in view of twentieth century disclosures about monasteries, seminaries, church schools, orphanages and state mental asylums. Throughout Christendom the insane were kept in insanitary conditions in mad-houses and exposed to public ridicule. The most famous place in England for such people was the hospital of St Mary of Bethlehem ("Bedlam"), where visitors were charged a fee to see the inmates, and were allowed to provoke them and laugh at them. A few inmates came to their senses, some died of old age, some died of neglect, starvation, exposure or torture, and many died of "putrid fever" or other infectious diseases that flourished in such conditions. The idea that demons caused insanity as well as physical illnesses was not restricted to the Catholic Church. Here is Martin Luther on the subject: My opinion of lunatics is, that all idiots and insane persons are possessed by devils, though on that account they will not be damned; but I think Satan tries men in different ways, some severely, some lightly, some for a long time, some for a short one. Physicians may attribute such things to natural causes, and sometimes cure them by medicene, but they are ignorant of the power of devils. (personal letter written by Martin Luther to Wenzel Link, dated July 14, 1528)
Christianity & Human Rights Christian Prooftexts …a rod is for the back of him that is void of understanding. Proverbs 10:13 According to Christians, lunatics were possessed by unclean spirits. To effect a cure it was therefore necessary to dislodge the offending spirit. This idea derived from gospel stories of exorcisms. And there was in their synagogue a man with an unclean spirit; and he cried out , Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art, The Holy One of God. And Jesus rebuked him, saying, Hold thy peace, and come out of him. Mark 1:23-25 Such beliefs had at least two unfortunate consequences. The first was that for many centuries no advance was made in understanding the nature of mental illness - although it is clear that Christians did understand the there was such a thing as insanity*. The second was that many thousands of men, women and children, already burdened with madness, were confined in chains and subjected to routine torture. The idea was that by making the environment sufficiently uncomfortable, the torturers might induce the possessing spirit to leave its human host. Saint Benedict beats a possessed monk, driving out the demon who possessed him. Fresco by Spinello Aretino (detail), Basilica San Miniato al Monte, Florence, Italy In some monasteries, the monks whipped their insane charges regularly every day. Although the method was spectacularly unsuccessful, no one seems to have realised the fact for many centuries. Sometimes the insane were beaten out of the parish with quarterstaffs. Sometimes they were loaded onto ships and sent off to die or become a problem for someone else. This is the origin of the various popular tales about a "ship of fools". A ship of fools. Those abord will almost certainly die - through accident, murder, starvation or shipwreck. This was an ideal way to kill the insane without feeling guilty. Christians could excuse themselves with the belief that if the insane they had forced aboard died, it must have been will.
Great content as usual. When you have time can you talk about the 20 meter Delta loop antenna in the vertical plane. Takes less space vertical plane and maybe quieter than a dipole. Thanks I subscribed a year ago and have used many of your ideas like the elevated vertical antenna with sucess,thank you . 73!😊
Hi Peter, I put up a 40m rotating dipole without rf choke or balun, and immediately I had rf in shack wipedout computer, installed a balun , helped a bit. But still rf, just watched your video about rf chokes. Great now I know I need one and ( WHY) . 👍, great informative videos. Been watching quite a few. Thanks sean GI7ULG. 73.
I had a somewhat larger *HORIZONTAL* loop antenna, about 8' up (around the eaves of my *_HOA controlled_* condo). I _"accidentally"_ discovered *NVIS* on 40/80 meters. I actually made a lot of DX contacts as far away as *Japan* and *South Africa!* *73 de AF6AS*
Thank you Peter for sharing your expertise and knowledge - especially on antennas. Your videos have proven very educational and helpful to me. 73! David, K7KDE
One of the things I like about your channel is your very correct English and calm way of speaking. I love amateur radio and I use your videos to find out what's new and practice my English.
My favorite and most frequently used antennas are my random wires, with 9:1 nelson matchboxes, a 41ft vertical and an 84ft sloper. Tried countless antennas prior. The band hopping the randoms allow, just spoiled me.
Very clear and instructive explanation of the random wire antenna, thanks Peter. What are your thoughts on clipping an EFHW/random wire to plastic guttering around the house if you cannot erect towers or poles? 73 Dave M0OOR.
Normally use an EFHW, but in some cases I use a 41ft 'random' wire. In mygarden I get 20, 17, 10, 6m on it, can't get 15m. I find it quite fussy with the length. It's only about 12 ft off the ground, and I've been shocked more than once at the DX on 100W.
question please. 71ft is my backyard [ish] now bewcause outer braid radiates can i use 71' and call it efficient . or what random length would most oppl use for hf harmonics please..yes i have chokes i just need ask can it equal radiator wire please
Just doing an EZNEC simulation on the 71ft stretch end fed, the input impedance at 7.15MHz is 2000 ohms, @10.15MHz, it's 8852 ohms, @14.15MHz it's 2068 ohms, @18.1MHz it's 159 ohms, @21.15MHz it's 1927 ohms, @24.95MHz it's 150 ohms, and @28.3MHz it's 1470 ohms. All of these are the resistive portions of the impedance. Nothing is particularly close to 450 ohms. There as a lot of reactive values all over the place though.
I agree it's well spec'd and very good value for money, but it's Windows centric. Good luck trying to work with Linux or Android. I made that mistake and there is no way of upgrading the firmware without a Windows PC. When you add the cost of a cheap PC it's no longer so cost effective. I simply do not understand what Yaesu are thinking of. I'm guessing they are tied in to Microsoft by contract.
I was an avid Yaesu user since the 70s. We used them in the military. It has driven me away from Yeasu. There is no reason why they cannot allow ftp telnet etc into their system. It has to be a Microsoft edict.
Thankyou Peter great vid i have a 71ft random wire antenna but its running through 49:1 unun and 7 clip on ferits and 15ft counterpoise seams to work alright should i change out the unun for a 9:1 ??? Thanks
Hello Thank you for the video. Super job. I don't know if you mentioned what should be the length of the fider - the power cable to the unun 9:1 with 71 feet of radiant? Greetings Mariusz SQ2ODE
Thank you Peter for all your advice. I would really appreciate it if you could do a item on tuning boat anchor radios. I have an old Yeasu 101zd which I love using now and then but never got to grips with the tuning of it. Takes me ages but I get there in the end. Just an idea 💡 God bless John G7GNS
The first antenna that I transmitted with was a center feed 100.' long piece copperweld (copper coated steel wire) feed with a home made balanced tuner via an open wire feedline. (a white plastic peg every foot) It worked FB on eighty and forty meters. (as a novice that is all that I could use it on) Resonance is not mandatory if you can properly tune it. Ron W4BIN
Palomar Engineers is an excellent place to obtain antenna parts, they offer ferrite beads and rings in several different mixes and suggestions on where and when to use them. Hope that shiner improves quickly. 73
Greetings, I like using the not so random wire when I go camping. It seems to work quite well on 40 - 10, but by using 71’ or 119’ I can rag chew on 80 meters. Also it’s shorter than the 80 meter EFHW counterpart which is easier to work with. I have a 119’ end fed up that isn’t much if any different than my 135’ Doublet (which I want to shorten to 115’) both are in an Inverted V configuration.
I recommend the "random" or long wire antenna. I have a 71 ft wire up right now that fills in very well in the space it is in. I also have a 155 ft wire that is essentially all band but the place it would be installed has a doublet up instead. The fact that all the bands can be easily tuned makes the long wire with a 9:1 Unun a very functional antenna. Look at it as if it is an off center fed dipole and tune it by moving the Common current choke on the cable. My tuner is an LDG autotuner.
My first portable antenna was a 41' random wire. It worked well on 40-10M with a 25' length of coax and a line isolator/choke. I've since built several others and use a switched 9:1/4:1 UnUn to optimize the match for each band. Antennas are sure fun! 73, Bill, W6QR
Thanks for sharing mate, always interesting to listen to. Now the eye, if you were swinging around on your hexbeam and went flying just say so, I won't tell anyone hi. Hope your both ok. Bands poor here. 73 zl3xdj.
Hi Brian, just hit a bad pot hole on my bike! Yes bands in doldrums and we are having a terrible summer.. Not much better than winter in ZL! Hope you both OK.
@@watersstanton roads are bad in places, got a ebike here, just pop down to the beach with dog in basket hi. Heavy rain here and snow on tops. Bands quiet, but not too bad. 73
Hello Peter, great food for thought in that video. The LW antenna can also be fed with 450Ω feeder which may be a better choice of feeder which would make an End Fed Zepp ? 73 Ger
Good video. I will just add a bit of history that you brought to my mind. I remember being 14 years old and having a long single wire. It was truly random. I was able to load it somewhat by sticking the wire into the SO-239 output of the DX-60 I had just built. Then I built a L network in a cardboard cigar box. I wound the coil around a 2 1/2 diameter insulator. Maybe 5 inches long. I has a small 140 pf variable. The ground was two short galvanized pipes just outside my bedroom window. I could work all the Novice bands. Over the past 60 years I found any length ( preferably over 1/4 wavelength) will work. Length can be truly random except the matching device must match the impedance to 50 ohm coax. Half wave end fed wires can be matched with 49:1 transformers or a quarter wave transmission line or an L network. Other lengths are matched with the appropriate transformer to suit the impedance at the feed point. Starting at the far end of the wire the impedance is high then as you move back it decreases to low or 50 ohms at 1/4 wave then increases until it is high again at 1/2 wave long. Mostly an L network works. Some lengths are more adaptable or easier for multiband use than others. All these names for antennas did not exist when we started they were all end fed wires. However they were all there, they just have new names! I don’t think anyone has invented any new antennas in recent years. I have many old books with forgotten antennas that are being rediscovered and renamed.
Mr Waters, a very well done video as always. I have had my General License in the USA for 1 year this month. I have experimented with dipoles, and end fed halve wave antenna, and vertical antennas. I decided to experiment with an end fed long wire antenna. I asked for advice on the QRZ forums and other various places. I was advised not to use one, but rather a resonant antenna. I live in town and have a small yard (garden). I decided to experiment. My final configuration is a 141 foot length of wire. I have used both a 9:1 unun and a remote Icom tuner at the antenna. I cannot tell much difference. I am currently using the 9:1 unun and a remote tuner in my radio room. I raise the wire up 26 feet. An inverted L. I then take the wire to the and of my yard to a peak of 42 feet to a carbon spider mast. I then angle it down and turn it. I is 3 feet off of the ground at the input side and final side. I did not ground anything. I have an elevated counterpoise. It is 3 feet high. I used moveable electric fence posts. The counterpoise wire is 3 feet from the ground and I ran it under the wire. I also ran a length of counterpoise approximately 45 degrees from the antenna wire. I have been able to make DX contacts on 160 meters as far as Indiana. I transmitted my signal over the Great Smokey Mountains. I am able to operate from 160 to 10 meters. With the opposing counterpoise it directs the energy so that I can achieve propagation even on the 160 meter band even with an antenna so low to the ground. I love long wire antennas. Thank you again for sharing the video. I have learned so very much from you in the last year. 73 sir. Ed, KM4MMD
Good job! A couple of winters ago I put up a very similar antenna and used it on Top Band (160 meters). It performed very well, even snagging a few European stations. Once we get back to long nights with little chance of thunderstorm activity (i.e., winter) I think you will be amazed at what you can accomplish on 160.
@@WilliamParmley Thank you for sharing that information. I appreciate it very much. You have given me encouragement to leave my antenna configuration the way it is. I may go back to the remote tuner instead of the unun, but I haven't noticed much of a loss using the unun.
Great, thanks. As a beginner I've made a random end-fed going up into my locust tree, of about 41ft in length (I will do a longer one at some point) into a 9:1 unun and to the transciever. Re: the coax as counterpoise and the use of a choke, I was told by a Ham Radio Outlet assistant to run a counterpoise from the ground terminal on the unun directly underneath the actual antenna wire and it seems to work fairly well, particularly on 40m. Does this method obviate the need for the choke described? Les. KK7TPM
Hi Peter Have you thought of a video about catsync for people with a high noise level unfortunately I have to use catsync due to high noise levels and it works very well
