Hi...
Can I simply build myself a switch box? Put each antenna onto a common bus
and use switches to assign to the various outputs that are connected to

the
various receivers?
Mark.


That's what I did. I used a 6-position rotary wafer switch that gives me 6
antenna positions. The output of the rotary switch feeds into a
single-pole-double-throw toggle switch. I also added a switched home built
attenuator between the wafer and toggle switch which gives me 0 to 35dB
attenuation selectable in 5dB steps.Now I can feed any of six antennas to
either of two receivers with just the flip of 2 switches. From a purity
point of view this is not the best setup as there is some crosstalk between
the antennas. But for a receive only situation, it works great and you would
have a hard time proving the crosstalk is of any real concern. Easy, fun,
and low cost too!
