I'd pick something UV resistant (some polycarbonate is, some isn't) - but I like the general idea - that lets the choke be in the open air, for better cooling. Zip ties if UV resistant are ok, but wi

Grant, after seeing several neat coil form designs in the style of Air Dux, I've been wondering if a precisely shaped groove might hold the wire reliably without glue. I imagine it snapping into plac

From a regulatory standpoint the latter isn't really workable. The adjacent property owner could build a new structure (barring setbacks, etc.) that's closer to the boundary, after the tower is up. _
I'm not trying to promote choke overkill, but look at it this way. If it is a truly high impedance CMC at the antenna, the shield of the remaining coax run to the shack is essentially a receiving ant
Although my 7 K0XG R65 rings have worked great minus one motor failure, I would do side mounts for future (unlikely) towers. The advantages of side mounts are lower cost & weight, using standard rota

I've been experimenting with an amplified receiving loop for 160/80 and trying to come up with a loop size that gives the best s/n ratio. I found that smaller loops in the 1.5 to 2 foot diameter rang

I should have clarified that I was speaking of the Rig Expert line. I'm wondering whether the ability to store multiple cal's on other units would overcome the ease of use of the AA devices - great U

Yeah, it's that "laches" thing - the problem is, it's non trivial to contest it, regardless if it has any chance of success. That is you've got to find an attorney who will do the motion to dismiss,
