I always wondered why some EUs cant hear me when they are S9+ on 40m. I see there is an 8KW capable filter available. I dont wonder any more. Ken K6MR Jukka, Jim, and Steve, Thank you for taking the

OM Power 4K is available for sale in the USA thru Array Solutions. Amp aside, these filters and triplexers get pretty hot. Unless conservatively rated, they will rapidly age and degrade performance.
Can anyone explain, Say youre using a SB0220 amp. I have seen this many many times recently. Explain this. improper amp loading/tuning. Or better yet what is proper amp loading/tuning. Joe WB9SBD Sig

For me the important lesson learned from this discussion is that stubs are not as easy as snip-snip you got yourself stubs. Deploying them takes planning and careful testing. That is, takes a lot of

I would guess most guys don't go to this much effort. New stuff and optimized placement? Wow, that would be cool! I built the stubs up on an as-needed basis with whatever I had laying about; there's

How do you guys do that? That is, how do you end up with all that coax without buying it? Or the connectors? I have purchased about 500' of LMR600 and maybe another 500' in LMR400 Flex. The Big Bang

This is very helpful and practical. How many stubs do you actually have? I am very curious how they all fit in a metal can. Do you mind sending me a few pictures to get a better idea? Rudy N2WQ Sent
I agree, If I have 5 bucks invested in my stubs I'd be amazed! And as shown before for less than 5 bucks they seem to work awful well. https://youtu.be/wgn_L_LUXcI Joe WB9SBD Sig The Original Rolling
That coax was stuff that I wouldn't even use on 160 meters. Outside for decades with nothing on the ends. Strip it back and braid as well as center conductor BLACK! Scrape with a knife to make shiny
Yes. That is, takes a lot of time. I spent about 6 hours on each set of double stubs -- one set to go on the 40M antenna, another for the 80M antenna for our CQP trailer. I did a very quick back of t

A stub attenuates the pass band signal. Please check your stub attenuation. Measure the power without and with the stub; using a separate power meter. About 10% power loss is barely acceptable. 5% is
Jim, Been following this thread since it started (this time) several days ago. I have lots of interest in it as I have a multi multi station here in VA. I have built coaxial stubs in the past using m
