Hello Bill: Take a look at some helpful papers by Greg, W8WWV: http://www.seed-solutions.com/gregordy/Amateur%20Radio/Experimentation/HexAr ray/UsingScope.htm http://www.seed-solutions.com/gregordy/A
Hello Dan! The original HyTower was designed for the "high end" of 80 meters (above 3.9 MHz). To use it below 3.9 required the addition of the base inductor. When I decided to build my 80 meter 4 squ
Hi Allen (and others)! Here is what I built: Length then Diameter Or Length then Face width for the 3 tower sections 96" 15.5" face 92.5" 13" face 92.5" 11" face 51" 2" OD 24" 2.5" OD 110.5" 2" OD 62
Hi Rob: It's not questionable - it's calculated. It's all about proper engineering. Engineer it right and you don't have a HyTower wet noodle - you have a really good 80 meter vertical. 20 years - wi
Hello Bob, As Len, W3GRF always said when asked about straight elements, "The DX will never know the difference"! Install it and get on the air. It will work fine. 73, Tim K3LR I am reading a thread
Another idea is a handy S-meter program written by Greg, W8WWV. This is what I use to test the patterns of all of my antennas. It works with many rigs. Once it is calibrated with your rig - it is ver
Hello Dick, We have used the DX Eng NCC-1 at K3LR for several years on 160 meters. It works great. It is hard to say which antennas work best with it because it varies. The low dipole (15 ft high) re
Hi Jim: I always wanted to test the 1/4 wave "insertion" theory, but never got around to it. I would love to hear what the difference is - if you can experiment. 73, Tim K3LR I'm building stubs for a
HI Blake, I am very interested in the 1032. Do you have photos you can email to me? 73, Tim With digital/rs232 control box, all documentation and software. Excellent condition, it's been in my garage
Sorry, no videos, however the PowerPoint presentations for the Antenna Forum since 2004 are available on the left side buttons at http://www.k3lr.com The 2010 Antenna forum papers will be posted shor
Hello Fred! I have used the Amphenol 83-1SP PL-259 UHF connector for years. It has a TFE insulator and a silver body. They are very easy to solder to. I have hundreds of these connectors in service w
The four excellent papers that were presented last week during Hamvention are now online (Thanks to K5TR). The 2010 Dayton Antenna forum had standing room only attendance during many of the talks. Th
Hi Pete, They were Russian made clones. They worked very well - the exact same as the real C3 antenna I had up for Field Day when we tested our entire setup (200 lbs of gear) before leaving to go to
Hello Scott, You can easily match 26 ohms (with no reactance) to 50 ohms with a one quarter wavelength piece of RG-83 coax (35 ohms) in series. Simply attach the proper length of RG-83 (246/F x VF =
Here is a super 2 element 40 meter Yagi. All of the hard design work has been completed. The feed system is even easier - via 50 ohm coax (suitable choke). I have two of these in the air and they wor
HI Kevin, I built two W6NL Moxon's. I have had them in the air for several years. They work perfectly. Nothing changes when the wind blows. The W6NL Moxon antenna has superior performance characteris
Hi Kevin, The W6NL Moxon is pretty simple (no matching components) and it is a 50 ohm feed. Check out: http://www.k3lr.com/engineering/moxon/W6NL_Moxon104.pdf The VSWR never gets over 1.4:1 from 7 to
Hello Mark, I have had good success with a 502 insulator - to make the Phillystran to EHS transition. I think the 502 is a safer route than shackles and thimbles that might cause either preform (Phil
Hi Jerry, Here are two mechanical designs for the 40 meter W6NL Moxon. Standard and heavy duty. The performance of the W6NL Moxon is very good. Good gain, good F/B and low VSWR across the entire band
