This is my channel all about amateur radio. I've been into radio since i was a teen, in 2007 i got my Foundation licence (M3YCM) and never used my call sign until about august 2019, then in the first covid lockdown hit and i got my intermediate (2E0SNC). Now a Full licence holder which i passed in the second lockdown. On this channel you will see videos of my station, me playing radio, doing projects and maybe some portable and mobile. Please like and Subscribe it helps me make more content
Thank you for your comment, if you don't like it....hey its not for you, i mean i feel bad. Taken time out of your day to watch it and you felt like you had to say its boring. You could always not watch it, if its not for you it's not for you
I dont seem to notice anything with my own solar system, i can isolate the 240v side and don't notice any difference, that said I'm surrounded by them so may not see any difference anyway
Nice one hope you pass, enjoying the hobby i hope. I placed down the wires then few weeks to let them sink into the grass/mud so i can cut the grass, some small plastic pegs are good to keep them where they should be, as for the siro 2016 it will be ok for 20m-10M but will be less effective at 20m will be good for 10m though (28MHz) good luck on your foundation
What size scaffolding poles did you use? I’m looking at doing the same with my cobwebb and I didn’t realise that there are so many different diameters!
The main mast is not a scaffolding pole, i got it from someone at my local club they are 3 section of poles that slide inside each other then bolted together making the mast approximately 8m high

Sorry to hear your having problems. My only input would be to lay the wire on the ground rather than raised and attached to the fence. Admittedly your installation is not that high off the ground, but I understand that as the loop is raised in height the polarisation becomes horizontal rather than vertical. If anyone reading this is considering buying a LOG kit, I would suggest buying from Radio-Stuff. Their kit including 20m of wire is £19.49 delivered.
I feel your pain. Its a struggle trying to set up a decent functional station in what looks like a typical small urban site. My first observation was you are trying lots of different things simultaneously so multiple wires and poles and feeders in situ. All these things interact with each other, even if not being used, even if not intentionally part of a antenna system. This interaction draws the noise or unwanted signals all over the site. Ground loops require a "clear" area of ground to work correctly. "clear" including in the context in radio current conducting things. So things like the QRM killer wire might be getting in the way just being there. Or its just proximity, your main end fed is inducing the noise its picking up into the ground loop. I know when I tried comparing two antennas simultaneously and switching back and forth I often saw little difference and it took years til it dawned on me the two antennas coupled together and ended up with pretty match the same signals! A personal opinion, end fed antennas. I dont get it, I dont rate them. I think they are a fad. Lots of chatter on RU-vid resulting in people trying them and finding the basic issue that unbalanced antennas are a PITA to actually use! Do you have all the balun/common mode choke malarkey in place? Is it working? Are you fooling yourself by hiding a basically nonfunctional antenna behind a tuner? 73 de G0AFV
Ive just moved my end fed up a mast so the transformer is 30ish feet in the air, it slopes down a bit to 5m after about 15/20m then comes down to my front garden, hoping this brings it away from the loop on the ground. Not going to give up got lots of testing to do
Thanks, ive been really enjoying it, i was talking to my local club and was asking do no one do RTTY anymore.....they said most people do ft4/8 now days. Ive done a livestream today and still doing another video. 73 M0KNM
hi its steven austin outdoors m7byf who was on your livestream the other night, anyway nice antenna the husler got a few friends who have them but i didn,t know you had a cobweb i have just got mine last week and its amazing 1.0 on every band its the 7 band one from poland but what i wanted to ask you is wot is that like fan dipole antenna you got comin from the cobweb looks ok and good luck with the husler 73 m7byf
Hi Steven yes i remember you, its my homemade " Cobra" dipole i wanted an antenna for 80m but that would fit my 8m garden, i have a RU-vid video about it
yes ill check it out because i bought the uk antennas 80m endfed for 80 and its good on every band except 80 wot i wanted it for lol how long is each leg because if its any good i might try one because our gardens about 10 11m 35ft both sides so it should fit ill have a look and see thanx mate @@M0KNM-Amateur-Radio
If i remember right there was over 123ft on each side, because there was only 50mm between each fold back i had to use more wire than a normal 80m dipole. I think its a case of experimenting to see what works for you, but defo start with more than 123ft.
@@M0KNM-Amateur-Radio Hope so Martin, noise is the bane of just about everyone these days, have problems from time to time with it myself. Cheers and all the best till the next time 👍
hello mate i have just put a cobweb up the 7 band one from poland and i have had australia 3 times this week brazil but its only 20ft at the moment waiting for better weather to put it 45ft up on a 20ft alloy scaffy pole on the roof but getting good reports on it now but i imagine it will be better up high and not sure thou how strong they are from m7byf
They are quite strong im sure as long as your mast can take it they will handle 100mph winds. Mines about 20/30ft in air and does well. The polish one is really good
i live on the side of ashhurst beacon im 500ft asl and at the top of the beacon its 750 asl and we get some strong winds but my 10m 3 elerment yagi was ok in 4 yrs up there but ill hold you to that and put it up in the summer but great antenna @@M0KNM-Amateur-Radio
Theres no problem at all using the ACC2 port with a computer interface, as long as its wired up to key the transceiver with pin 9. I use a Rig Expert TI-3000 with my TS-2000 and it works perfectly for FT8 on HF or packet over the GreenCube IO-117 UHF satellite.
Did you not understand it? Or was it not for you? If you did not understand anything please let me know what it is and i will try and answer, if it wasn't for you then its not for you....its all good you win some you loose some but i wish you all the luck. 73 M0KNM
If your happy with the transmit of your Cobra antenna, you might want to consider a Loop On The Ground receive antenna to go along with it. LoG's seem to be gaining popularity in noisy environments. Several people have Videos here, and there are several websites about them. 20 years ago when I was on 160m I used a K9FD Receiving Loop (Magnetic rx loop) consisting of 20 feet of RG6 coax and a trimmer capacitor on a + frame of PVC pipe. (10 foot coax loop would be needed for 80/75m) A bit later the K9AY recieve loop gained popularity, but its a bit more of a space hog. Sometimes (and on 80/75 and 160m) you just need to use separate TX and RX antennas to get the job done. 73 mike N4ONL
Great video, yes I have one and it is (was) the best omnidirectional antenna. Where there is a lot of light there is also shadow. 1. Very narrow band. 2. extremely sensitive to moisture and 3. very sensitive to a lot of snow. Mine was totally destroyed this year and the elements were completely pushed down. And now I'm thinking about whether I should buy or build one again.
I found mine widebanded, but i do find it sensitive to moisture too, im going to learn more about it and want to make new elements for it maybe in the summer 73 M0KNM
Have you checked that all wires are intact and not broken inside the PVC? Short-circuit the wires at the balun and measure between the end pieces for each antenna to see if they are short-circuited. If they are shorted, the wire is fine, if they are not shorted, replace the wire.
Hi, yes i did check if there was a short at the balun....there was, though i think maybe in the summer i might need to change wire it was ok but starting to look like it was going bad. Nice project for the summer i think. 73 de M0KNM
Fair play to you, great to see people out experimenting and building their own antenna to fit within the constraints of your local conditions. Keep it up. You should try building a horizontal loop , as long as you can fit in, shape not important. Great antennas, very quiet on RX. Use a 4:1 balun at the feed point. Useful multiband antenna, resonant or not. I have one 1000 ft long. Works extremely well. But a much shorter one will work well too on the higher frequencies. . GI0UTE
Yeah i wanted to make my own as i wanted to get onto 80m as i do alot of contests for myself and my local club. I needed it to fit into my 8m garden so was doing alot of hunting on tinterweb and found this. Its not ideal but im thinking about doing a 2.0 version of it maybe with bigger gaps between the passthrough's, it might make it resonant with less wire (there is more than 1/4 on each leg)
With all those traps and coils, it looks like a vertical dummy load to me, especially on the lower frequencies. Why not use a DX commander? Its a no compromise vertical. Just my opinion. GI0UTE
I did think about a DX Commander it was just someone at my local club said they got this and would i like it, ive not heard anything really bad about them
I bought a 5btv before doing much research on them, after reading comments like yours I was really disheartened and almost just sold it on (expecting to find it’s a dummy load), thankfully I didn’t because after from 10m and 80m it’s a fantastic antenna, I’ve worked all continents on it. Broke through pile ups and just this week worked the J38R DXpedition on 40m CW running 100w and a tiny system of radials
I have this exact antenna but under a different name, Harvest HFC-6S. If i can get the length correct on the coils, it will work well. I believe the recorded measurements in the instructions are wrong. I am looking forward to part 2.
Have been trying to do part 2 but by the looks of things 2 elements are not working, 7mhz element i get no reading as well as the 21mhz element. Looks like ill have to stop for a bit to do an RMA return
Great video, thanks. I'm toying with the idea of building one; any opinions are welcome at this stage. Did you get it any higher? I used to chat with scaffolders; for a couple of 6-packs of beer they would allow a 24ft+ pole to drop off their truck near me... Heavy, but great for antenna mounts!
Thank you, i they are a good antenna for 20m to 10m, not tried it on 6m and 2m but it does have a drop in VSWR on them bands. It was hard to tune at first but got there in the end, i got it to about 8/9m above ground in the end, i just need to make a ratchet system to help me lower it more easy.
why are you on 40mtrs the cobwebb is not designed / tuned for 40mtrs the original tpw cobwebb its 20 to 10mtrs. bit of a pointless video really is it not..?
Not a pointless video really no, it tuned up on 40m because of where it was ( a temp place ) . Because of its surroundings and close to the ground, if you see another video it explains that it does not tune up on 40m and if it did it would not be Suitable for that band
@@M0KNM-Amateur-Radio Just because a tuner can tune it on 40, does not mean it's going to work well. Your tuner might tune up a bed spring but a bed spring will make a lousy antenna. Should have done the test on 20 - 10 meter bands, where the Cobwebb is resonant. Because you can speak to Klaus in Berlin on 40 meters also means nothing.
I do not calculate the multipliers, i just contact who i can, i just enjoy the contest i dont chase the end points.....if i get the multipliers its a bonus, if i dont....i dont
