[TenTec] antenna switches

[Phil Sussman]

TO MODERATOR: Sorry for the previous sending goofs - my fat fingers at work.
I appologize .. Phil


Paul,

I've used bunches of A/D switches, both the 2 and 4 position. The only
times that I've seen failures were.

1. Hot switching - turning the switch with a lot of RF power applied.

2. Bad Pellet - check the breakdown voltage of the pellet. Chances are
the pellet is open (out of gas) and not protecting the contacts. I have
not had an A/D break except for physical (the knob was sheered off).

3. Arc over - a direct lightning strike when the contacts were fused
together and the coaxial cable (on the antenna side) melted. Note the
connected radio was NOT damaged.
