When I cut wire, I cut a little long. I have a rule of thumb going between metric and standard. One meter is approximately 3.2 feet or slightly bigger than a yard. I find that even as i have gained experience, a reminder of the basics can help. I really like what you do. I also get a good laugh with some of the differences in the way the British and Americans say things.

Thanks Calum, us who do not have the magic black box antenna tuners or an antenna analyser your explanations are great, especially using metric measurements in relation to the bands. I think it all comes down to 10 +- meters for an antenna 1/4 wave 10 meters for each element, then you have the resonant frequencies which I believe are the other bands which the antenna will work on being multiples of 10?????. If using the 80 meter band then each element is twice the length used on the 40 meter band. 10 meter band the elements are 2.5 meters +-. I know that there is math calculations that give you the exact length, but the plus minus length estimate is for tuning...always easier to make the elements a little longer for trimming.

@AZREDFERN
@AZREDFERN 8 месяцев назад
A proper vertical is just a folded dipole that can’t decide which direction it wants to face. But why doesn’t it need to play by the same rules? Dipoles are hard to use an antenna tuner on, and each pole needs to be the same length. But a vertical doesn’t care how long the radials, neutral/negative, are. You can also tune a 6 meter tall whip to anything between 10 and 80 meters with a good antenna tuner. I keep looking into other antenna concepts, but I keep coming back to verticals for their simplicity and decent performance.
@DXCommanderHQ
@DXCommanderHQ 8 месяцев назад
Well.. It sort-of does care how long it is - but only for "us" because the longer an antenna gets in comparison to the wavelength, the pattern changes quite a lot. Ideally, a tuned quarter wave with some radials works great with no tuner.. But hey, everything "works"..! LOL :)

Good Video Callum! You do antennas the fun way, skipping the middleman. You take a basic concept and make it work Hands On, rather than Over Engineering them, and still needing Hands On to dial them in anyway. Keep spreading the Good Word. More people need to realize antennas aren't as hard or critical to build as the purists want us to think. Building antennas is another Hands On way to enjoy Ham Radio, especially when you finally work New Zealand on an antenna you built! 73 mike N4ONL EDIT ADD LINK: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OJy-XjGYlGw.html

Thanks for more great info and clear explanations. So, I got a 4:1 balun to set up a better LoG in my backyard for SW listening as I mentioned before, and I decided to utilise the full area of said garden, but this means two legs of the antenna are longer than the others (roughly 50ft wide and 30ft deep). Before, I had a far smaller (but less 'lop-sided') one just resting on the lawn to try out the concept after seeing your specific vid on LoGs. I can't help feeling the former was maybe more sensitive - and I initialy set it up without a balun, just having one 18-gauge speaker wire coming from the 2-terminal antenna adapter on the radio and back to its ground. I also tried it with two speaker wires (i.e before splitting the two halves). Is it inadvisable then to have a larger loop with unequal legs, and should I go back to something smaller but more symetrical? Also, even with the balun I can't help feeling the noise level is still quite high, although that could I assume, be proximity to the house and the presence of other noise sources close by in the neighbourhood. Excuse the novel. So much to learn and try to perfect before I even think about pursuing transmitting as well as receiving.😁

I am not yet a ham . I am a 11meter baby. No haters. I also enjoy my gmrs radios . As i study for the ham test i am amazed at the multitude of available radios and antennas and how things have changed from the 70s to now . I have also found digital to be a bit perplexing, subject maybe for another day. I woder tho do you have any videos on 11 meter antennas or would you consider doin a fucus on 11 meters and another on 2meter and 70cm i feel at 59 i am late in the game to be tryin to learn how to build antennas . I was in the army and raising 7 children i was always to busy for the radio hobby . And now i have the time , and retired now far less income . Rambling on now. Anyway 73s great video.

Callum, from S.E.Tennessee - your plain speaking is greatly appreciated. You have given me the encouragement to go out and experiment on my small holding. In the end, though, I really just want my signal to “get out there” as far and strong and clear as possible. Also interesting - the idea of a receive (only) antenna. Does that imply separate antennas for receive and transmit? Perhaps a silly query, if so, please excuse a newbie’s ignorance. Cheers - KQ4IXD

@ArnieDXer
@ArnieDXer Год назад
Callum, you mentioned linear loading & coiling in this presentation. Well I was thinking about a different type of space constraint - I can basically squeeze in a hundred of metres or so of wire to one direction (or two, if it's bidirectional), but my backyard room doesn't allow other directions I'm particularly interested in. Like, I could point it at UK or US to one side or India/Middle East to the other from Poland but I'd rather get Japan & Korea out of that wire antenna. Can adding a bit of wire perpendicularly at the far end help? I imagine the pattern should skew towards the new far end, but how much? And will it work for a longwire as well as a beverage? Or am I risking spurious leaves off-the-sides? 73, Arnie
@DXCommanderHQ
@DXCommanderHQ Год назад
Now.. Interesting question.. You want to "skew" the pattern and honestly, I really don't know the answer.. Mine has about a 10 degree kink in it and to be honest, I am facing perhaps Mexico rather than say Seattle (I am too far south) so more experiments required in that department.

When I lived in the city... I had a nice tall 80 ft tree... I ran my coax to the tree and I attached three aerials one was cut for 160 another for $80 and another for 40 m I had quite a few radials that were just stapled to the ground with lawn staples and I just use galvanized steel fence wire... I also connected to the fence of the property as well as the water line and my two car steel garage The result wasn't antenna that worked all the way from 160 up to 6 m... For that matter it even presented a usable match it two meters It was an extremely loud talker on 160 through 40 Although it wasn't very good at listening on 160 due to all the noise it would pick up I still made quite a few contacts using this antenna... And I referred to it as a fan vertical Obviously the 160 and 80 aerials were more of an inverted L

Thankds sir Calum for this very informative video which has given me some ideas, specifically a small LoG RX antenna to combat local QRM from LED streetlights and neighbors' fairy lights. I'm still not licensed yet (awaiting my countries' communications authority to schedule an exam in my region) but I've built an experimental vertical traveling-wave antenna (it needs a good ATU to TX) out of 7.3 meters of twinlead appliance cord with 1.5 meters removed from one side at the top. a 4:1 transformer, and a few counterpoises.I've been able to RX very well and pick up stations on FT8 (on various bands) from all over the globe. It's a sort of Rybakov/OCF 43 foot vertical hybrid or something. You might have fun experimenting with this. 73 de Jay PK10.

And, just to push my luck, what do you think would happen if you moved the 'cap hat' from the top of the antenna to half-way down the antenna - i.e. - from the top of a 1/4 wave vertical to half-way down the vertical? Would this 'increase' or 'decrease' the lowering of the radiation angle, and therefore lessen or enhance the DX range? Any thoughts would be appreciated. Thank you.

@mikeymouse4629
@mikeymouse4629 Год назад
Wow. Distilled knowledge - in a 'nutshell'. 🙂 Can I ask, what would you think the effect of adding a 'capacitance hat' to a vertical antenna in the hopes of increasing the DX range of the transmissions? Since the 'cap hat' tends to electronically 'lengthen' the antenna, and thus making a 1/4 wave look more like a 1/2 wave antenna, and since 1/2 wave antennas have a lower angle of radiation, would the 'cap hat' tend to 'push down', or lower the angle, more than a plain 1/4 wave antenna, and therefore have more radiated power at 5 degrees? Any advice would be appreciated. Thank you.
@DXCommanderHQ
@DXCommanderHQ Год назад
Ah-ha.. You say 1/2 wave has lower radiation.. So I don't think so. On moderate ground, they are neck-and-neck. Anyway,, if you make it too long, you would have to match it with a transformer so a cap hat means you would have to reduce the overall length..
@mikeymouse4629
@mikeymouse4629 Год назад
@@DXCommanderHQ Thank you for the reply. Interesting - I had seen some graphs that (I thought) showed that the lobe pattern for a vertical 1/2 wave was lower than that of the 1/4 wave. I'll have to look at that again. So, in my case, (Chameleon MPAS 2.0) 7 meter vertical antenna with a cap-hat half-way down, do you think that the cap-hat is lowering the take off angle, or is it just 'messing things up' as far as the radiation patterns are concerned. Any advice / guesses would be much appreciated. Cheers.
@DXCommanderHQ
@DXCommanderHQ Год назад
You are correct.. On the surface, the half-wave LOOKS that it must be better. Until you actually measure the radiation. Basically the quarter wave ALSO has some higher up gain but with 32 radials on moderate ground, they measure equal. Changing the ground to 16 radials (4 wavelengths) the half-wave is 1dB better at 5 degrees off the deck. You would never notice it.

Mind impedance and voltage/current behaviors for optimal EMF performance. 'Resonance', proper match to transmitter suggests 50 ohms +/- impedance at the feedpoint. So a 7.2 MHz antenna is not 50 ohms @ 15 meters... it's a non-50-ohm harmonic relationship at 21.6 MHz - outside the amateur spectrum.

Genuinely on a church? Well in the UK, we have a lot of old churches - and they normally have bell-towers which is an easy fix. On a modern church, around the back.. For VHF, get it HIGH. On HF eg 40m, it doesn't matter so much. If 20m and above, for instance for DX, you really need to be up at least half a wavelength (unless it's a vertical - verticals have lower angle radiation anyway - unless your Yagi or dipole is HIGH))

Callum, could you do a video on a vertical dipole vs a vertical, for say 10m I an interested in the modeling. I actually put a vertical dipole on the side of my house for 10m. It was completely above the roof, and the performance was unbelievable It was cheap and cheerful and the feedpoint came out at 90 degrees on a piece of cane.I was getting contacted by Aruba every morning on low power.
@DXCommanderHQ
@DXCommanderHQ 5 месяцев назад
Yes, I'll add that to the list. If will perform very well.

FT902 had the preamp on by default and there is no need for a preamp on unless you are in the middle of nowhere and you are working on the higher bands.

Thanks again Cal, you’ve taught me why I have such a narrow usable swr range on the 80M portion of my efhw. The coil that shortens it (for 80M)! I might have to eliminate it and put an extra 20 meters of wire up. Might have to move my feed end back a bit to fit it all in my block. 73

@richardcallihan9746
@richardcallihan9746 Год назад
Probably a stupid question, at 38:11 When you are drawing the coil CCW {referencing the feed-point side of the coil} should the other side be the same CCW or CW, or it doesn't matter? 🤔

Good question - but it doesn't matter. Nice one..

Explain why you would not use a 49:1 Unun on your DXC…. I was told it needs one…. Told Ihem Idon’t have one on mine. And it work’s awesome!
@DXCommanderHQ
@DXCommanderHQ Год назад
Woah! You don't need a transformer..! Whoever told you, is totally out of touch. You should get around 50 ohms with direct connect coax. If it was a half-wave end-fed, then yes, you will need 49:1 or 64:1 BUT these are essentially quarter waves or harmonics.

A really good vid Cal. A question if you don't mind. How would a loop of wire vice radials work on your wonders of magic? Example, a back yard of 15m x 10m loop, on the ground. I know, buy one and try it out and let you have the results... 🤣🤣 73, Gary
