Congrats Ron! You will really like this antenna! We used a stack of these antennas during the past 4 DX contests for our 40 meter second station and they worked great! For those wanting the conversio
HI Ron! Yes, I understand the two camps! DX propagation conditions were very challenging on 40 meters for the last 4 DX contests. The K3LR 40 meter operators did lots of comparisons during the past s
Hi Gregg! I have been using the W0IYH bead choke for years on all of my antennas. They work super and run cold at 1500 watts. No problems. You can build one (100 beads and 40 inches of RG-142 coax) f
Hello Jeff! I have used the Top Ten switch to switch between transceivers. These switches have at least 80 dB of isolation and work very well. Here is the link: http://www.qth.com/topten/abss.htm 73!

Bill: I have had great success with TIC rings over the past 20 years. The pots that are being used now seem to hold up better than the old ones. You will not need a "mast plate" when you mount your a
Hi Denny! I assembled almost every one of the TIC rings I have up. I've spent lots of time figuring out how they work (strengths and weaknesses) and what can be done to make them more reliable. I als
Hello James! I have soldered lots of PL259s on LMR400 direct bury coax using this method: http://www.k3lr.com/engineering/pl259/ Check it out. It should work well for you too. 73! Tim K3LR http://www
Hi Rex! There is nothing "special" about the coax I use for this method! Regular ol' coax works great - soldering it on the back of the PL-259 as I show in the pictures. With this procedure there is

Hi Tony! See if you can borrow a different balanced feed antenna tuner as a test. Maybe there is a problem with your ATR-30. Your antenna should work great, so don't give up! 73! Tim K3LR Can somone

Hello Dick: I use the W0IYH design choke on all of my antennas and at the amplifier output. They use RG-412 coax cable. You can order them from Comtek Systems. http://comteksystems.com/ 73! Tim K3LR

Hello John! Dave, W6NL is very busy and can be out of touch because of his work. I have built, installed and used two of these antennas. They are visible in this picture: http://www.k3lr.com/2007/pho
Hello Tony! Back in the 70s and 80s I used two 203Bas. They worked great. Simple and straight forward. No problems. 73! Tim K3LR Hello to all, I cannot seem to find much feedback on the 203ba. It see
Gregg/Jim, What Frank said below is right on target. As another example: The K3LR 80 meter verticals use the basic HyGain HyTower as their building block. The original HyTower was 51 ft in total leng
