I used to have similar antenna Comet CHA 250 , at urban crowded , tight space housing complex, vertical antenna's noise was so high, it was not suitable for receiving, but for any frequency higher than 14 MHz, it worked OK, I change to inverted L since I do mostly 10MHz and below. AG6JU
I have one too. It's in the shed because i don't have space anymore. Apartment. Used it in the past. But not in optimal setup. Wasn't that impressed at the time with TX. Made the antenne 1.5 meter longer and used a PVC coil to tune it up to 40 meters. Mono band. That didn't do bad! Also tried it with a 9:1 balun but not a good SWR on all bands. My conclusion: I can't use the antenna right now. If i ever move again, this thing goes on the roof or in the garden with radials. Its nice stealth. Original balun is be used for wideband SW RX coverage and its a good feeling that it can TX everywhere. I love the antenna. Would not recommend it for new users. It's expensive. There are better solutions and much cheaper.
Im about to purchase a vertical antenna and can't make my mind up between the Diamond BB7V and the Comet CHA 250 it will be permanently fixed to the rear of the house at a height of roughly 18 feet, im told the Diamond works better closer to the ground not sure if this is correct !! Im also in South Wales
Yes the diamond BB7V does perform better closer to the ground. Having it higher may give you slightly higher SWR readings, I’m not sure about the CHA 250. Hopefully catch you on the air on my next visit to South Wales 👍
Hi Jason very impressive antenna and the results you got on the main HF bands was just amazing and your antenna was only a couple of foot off the ground and it still worked brilliant so now that I've seen it in action I might buy one myself and test it out I've got a Yaesu FT-950 and I'll be able to get the SWR down with the automatic ATU built in to my radio no problem at all so I'm going to invest in getting one very soon. Thanks and best 73's for now cheers Stephen M3SNV 73's.
I've been toying with the idea of getting one of these antennas as I'm working from a narrowboat and so have limited options as far as antennas go. I've been messing around with some Ampro hamsticks with mixed results so looking at something else. I think this antenna might be just what I'm looking for. Cheers and 73s!
Hello, i'm just looking for this video ... today a fellow hamradio shared is setup at POTA Group Facebook and reported very nice signals with this antenna As I operate QRP also with my X6100 this video is very importan and useful SWR values are really very goods ... at 10 M swr was 2:3 ... the X6100 tuner managed to tune it? Many thanks for sharing / 73 CS7BDO
@@jason2e1hko59 hi Jason. Look forward to that one. I have about 100 feet of rg58 coax on this one. I might try rg213 and see if it makes any difference. I have had not had much luck with 40 MTRS on ours. Will keep playing. 👍
Just a glorified dummy load . Far too expensive when you can get better results for a fraction of the cost with a ten meter fishing pole and a 9.1 unun
