Wow, got a care package from the MOP man today. This the biggest feedline switch I've ever seen. Now I gotta figure out what teh best usage of it would be. I could use it as a shunt feedlines to ground safety, or I could use it to switch 2 antennas to one tuna or the same antenna to 2 different tunas. if you had this, would would you use it for? Tnx Phred!  |

WOW want a nice switch, that's just what I need to
switch my G5RV into a Marconi for 160.
Maybe there's another one out there somewhere.

Hey Derb,
If that is a SA-13/U, I think it was used in B-29 aircraft to switch the antenna. It is a beast!

That'd be a damn shame to burn that bone with a static discharge to ground.
I'd use it to switch phase on your open wire feedline. "X" pattern. Sometimes a favorable lobe shows up one t'other.
Come storm season, ground that sucka outside and come back later.

I have used one of those switches for decades. Also have a couple that are SPDT but otherwise identical, that I picked up somewhere.

Yep. That's the puppy. Now I gotta figure how best to mount it up. Lotsa final outside construction going on right now. It's 68 degrees today. Gotta take advantage of that before we are back to 22 degrees.

That Thar switch was a nice one from Surplus Sales.
WHEN you can afford their stuff, it's worth it. Usually clean used or mostly NOS. They must have gotten a nice deal on the goodies from (was it??) Los Alamos??? A research lab, possibly from area 51 fame.

It's a ground system worthy of the best 1920's spark outfit, Ed. Which is good, because the ac mains grounds is quite iffy. There some funny business going on in the Square D box too.

You could fire up the Frankenstein monster with that buzzardly hunk.
