[TowerTalk] 6m QRO 2 Position Manual Antenna/Coax Switch

[WW3S]

The switches fail short as well, but easy to change them out in the shack.....plus, the alpha delta have mil-spec numbers.....several in use here with nary a problem, and yes DXE good price, great service and shipping are a plus....

I HAVE looked inside, since I had one that was bad. It wasn't broken, it was MADE that way, with a part missing so that there was no way that position #4 was going to work. So much for final test. Electrically they're fine. The 1x2's are made the same way.

When it fries (shorted) on a lightning discharge or too much TX power, the antenna must be lowered to correct the problem. That can be a real PITA, depending on how the dipole is rigged. And, IMO, it's the wrong place for a GDT to protect the radio. This was one of a half-dozen dipole insulators I bought to figure out which were suitable for my needs.
