Hi John I have used LMR-600uf outdoors for ~20 years. I have not seen any issues with degradations due to uV here is north Texas. At least when compared to LMR400 runs in parallel with it. I spoke wi
Hi Stan, In the past at Andrew's QTH (ZF1EJ) we had issues with the standard 8 wire terminal blocks deterioating quickly, some literally into dust in 1-2 years. That salt fog is a real PITA. I use 25
Greetings All, I was considering a similar approach, by taking the existing design and changing the linear loaded elements into center loaded dipoles. Start with coil placement at LL insulator and tu
One data point is worth a thousand opinions here. Try it, you may find the differences a non issue. And if they are, build an antenna for the other direction. 73' Mike K9MK Dude. Kindred souls - I wo
I used FSJ4 as the rotor loop for a VHF array. It lasted about a year when the coax shield cracked and eventually opened up. Good stuff when it worked, infinite SWR when it didn't. The replacement, a
Greetings to the group. I just finished burying and pulling a lot of LMR-600-DB and where that come to ground I pulled them through a chase to protect them from the almighty weed whacker and such. Th
Greetings, Without going to UST, I have been trying to locate a replacement pulley/sheave for my HDX-555 tower. This is sheave that the raising cable uses. There are two slots but there was only one
Greetings again, Thanks to all that responded. Several new leads had the same inventory as Grangier and Zoro and others... Seems this 3.5" aluminum bearing sheave is a one off and the closest I can f
Would a Hardie board work here. The "secret" to using wood outdoors is to soak it down good with Thompson's Water Seal (following label directions) before painting. Last's a VERY long time! Tempered
Ditto Mark, I had a Pro-67C3 up for almost 20 years without issues, including several ice storms with 1" ice. Very robust and it stood up to most 3-4 element yagi's in the area. Computer modeling of

Bob W5FKN does rebuilds on tailtwisters (and most of the hygain rotors). Has anyone sent theirs to MFJ for a refurbish? I got one off a tower up since the '70's. It works but I have no history on it
Greetings, I have a couple unused TIC 1022D (maybe they're 1032's Ring Rotors) that I was thinking about using on either a HDX-555-MDPL or HDX-589-MDPL tower. Looking at the web site these appear to
Alan, I had an original G2800 with a 4-bolt mast cup at my former QTH. It held a Mosley Pro-67C3 on it. Not a long boom antenna but a sprawling antenna that was heavy. And it really flexed around in
