Does anyone have contact information for the Ham who is building jpole antenna's.  He was at the DRM event in Blaine this past summer and then the APRS gathering in September.  I believe he lives in or near Everett.

It’s K9JEB. You can see his antennas at: http://k9jeb.com/

He runs ads on Craigslist go to the electronics section and search for ham radio

His J-Pole and Anderson distribution boxes are always on there.

I would like to see a comparison between his J-pole and the $50 Tram from Home Depot

The Tram has it beat by a mile! I think his come in around 3db. Don't get me wrong they are great and I own two of them but the tram will perform really well at a great price point! My 10 cents.

Andy,  I still don't have much of a clue about antennas and don't know what you mean by "his come in about 3db".  Remington and I have been running some SWR tests on the jpole I got from K9JEB and the readings across both the vhf and uhf bands were something like 1:1 and 1:1.6 for almost the entire width of the ban if memory serves me.  I bought a diamond 50x  which looks similar to the TRAM offered by Home Depot and while the vhf swr was between below 1:2 the uhf was up about 1:5 or useless.  Lots to learn about all of this.

Yes. The gentlemen who makes those is incredible good at what he does and he has a very proven design! His SWR match is dialed in. DB is referring to something different though. I Don't have the written definition so forgive me. Look at SWR as balance and DB as reach. You can have great balance with a light reach and that's ok. Or you can have a Large reach with great balance. But without balance reach means nothing. That's my compressed way of looking at it. In regards to your Diamond 50x there are many things that can contribute to a SWR that may be off a smidge. that said 1.2 to 1 vhf and 1.5 to 1 uhf is a very usable match. Ok I'm going to stop with my ramble. Either way keep up the good work!
