Good morning all, I hope you had a nice holiday. Part of prepping for the January contest included taking down the stack ofM2 6M7antennas and tuning them a bit higher to accommodate FT8/4 frequencies

Can't really offer you much help. But, about six months ago, I did what you are trying to do with my Five element M2. I did it without adjusting element lengths. (I agree, moving the shorting bars ou

Well, misery loves company. Thanks for the feedback.I plan on calling M2 on Monday but was hoping to finish this project this weekend. 2m tower still needs attention. Hope to work you in January. Btw
Hello Paul. I had the exact same problem last year when I was setting up to operate from home in the June and September contests. I also have a 6M7 and after a weekend of trying I was also unable to
When the FT8 bug infected everyone a few years back, I retuned 2 original 6M7's high enough to be 1.5:1 at 50.313 by moving the t-match shorting bars as far outboard as they would go. Yes, the origin
I think the problem is that the Q of the antenna is so high that the elements cannot supply a reasonable reactance at the FT-8 frequency for the matching section to work with. The solution is to try
Good morning all, It appears that I'm not alone with this issue. It's a great antenna until you try to push up the band for the digital modes, with potential for more to come. So far I've learned thi

If you've not already thought of it, hang the antenna pointing straight up -- with the reflector as far off the ground as practical. HNY, Jonesy -- Marvin L Jones | W3DHJ | W3DHJ | https://W3DHJ.net/

Hi Paul,No help here with the issue, but I wanted to thank you and the list for the topic. I currently have a CC 6 element on a small tower. I have a bigger tower I hope to put up soon, and I've bee
This brings up again the age old question: do I want to DX or contest? A high gain, narrow band antenna does not send a CQ in a wide azimuth. But today's rules allow you to call someone on your cellp
That is my thinking also. You can have a single really large antenna with a narrow beam width or stack two (or more) smaller antennas. 73 Jim, W4KXY Sent from my iPad ________________________________

Interesting thread. I face a similar band width problem but fortunately conquered it with a lot of help. I need to run SSB, FT8 at the low end (50.125-50.313) and FM (52.525) at the high end. With

Why was a frequency so far from 50.125 chosen for FT8? Mike That is my thinking also. You can have a single really large antenna with a narrow beam width or stack two (or more) smaller antennas. 73 J
I quit! 3 hours of messing with that antenna and I got nowhere. It's starting to snow. Maybe we'll get enough to bury them. The theory behind moving the shorting bars out to more the freq up the band
I'd be a little more interested in what was done to resonate the Cushcraft yagi. I have the newer 6 element version and using the "factory recommended " settings my resonate point with the best SWR i
Interesting discussion, I have Cushcraft 6 meter, 3 element, adjusted it many times, best I can get at 50.125 is 2.2:1, considering taking it down and trying something else. Emory WM3M On 1/3/2021 1

K3SK, My tune has BAD VSWR between the SSB and FM portions of the band, but I dont use it there. The point being its not totally flat. The fellow who helped me out with that tune put a lot of effort
