[TenTec] Antenna Switch

[Ron Morell]

This is a word of caution.  I've used switching combinations between several
transceivers and antennas for a time now and it is convenient, but make
certain that you have a high degree of isolation in your switch or you might
find the front end of your connected receivers damaged by the transmissions.
60db of isolation would be good idea.  A switch that grounds unused inputs
is excellent choice for this duty, especially if you are running any power
out.  I've enjoyed replacing diodes in a couple of ten tec receivers now,
because of poor isolation in the switches used.  HI

Rick,

I recently had 2 antennas and 2 rigs wired through 2
switches.

The first switch is a B&W 6 position antenna switch
with 1 common(rig) outlet that was connected to the
common (rig) input to a TT Model 228 tuner.

The DL (dummy load) connection went to the #1 rig and
the Bypass connection went to the #2 rig.

My #1 antenna is a G5RV with an RT-11 remote tuner
attached outside and the #2 antenna is my 180 ft
horizontal loop rain gutter with an AT-100 Pro tuner
attached in the shack.

I could switch the 2 antennas between the rigs or
switch the rigs on 1 antenna. The latter is very handy
for comparing the receiver performance of 2 rigs.

Regards,

Don NN8B

Hi,
 
Anybody out there using an antenna switch to match two
antennas to two  
rigs? 
 Or using two switches to match two antennas to two
rigs?
