Remote Antenna Disconnect

Hi Rick

Those work.   The relays in those boxes have a very small space, maybe 2mm and lightning can easily jump across.

Some of us are looking for a bit more distance between the contacts on a total lightning disconnect in case of a closer strike.  

For a remote operator, this is as close as you can come to tossing the coax back out the window!

That is correct. One of the only steps missing for making my shack better and safer and distance friendly.

The UHF connectors are a push-on type typically used for bench work.  

Many connector types have similar push-on versions available (pretty certain F, N, UHF, SMA and a few more).

I think with N-connectors the usual ****-together is not a true shield electrical connection.

You can put me in with one assembled (I´m no good in making stuff myself).

@Mark WS7M - what operating temperatures are your providing for?  (Without adding heat or cooling figuring -40c to +50c would capture my QTH's extremes.)

What distance are you thinking to displace things by?

I had a lightning strike this summer in the backyard. The only damaged was two gallium fuses in my lightning arrestors shorted to ground protecting my system. I don't turn the power off on any of my gear, that way the differential voltage remains stable.

The distance right now is like 4 inches but that dimension is not yet final.

The connectors are going to be "shock mounted" which is the ME's way of saying there will be some give to help with alignment.

But I am open to temperature range recommendations.  

For me personally it will always be in a dry place between 40F and 90F as it will be in an HVAC room which probably stays closer to 65 all the time.

I think to fit your -40C to +50C would be tough for almost any mechanical assembly with mating parts.  For something requiring that we might have to use more stable materials (added expense) and maybe thicker surfaces.  I'll ask the ME to be sure.

Please check this video. This is my implementation of the same concept.
