Topband: Passive Receive Antenna Splitter

[Charlie Cunningham]

That should work fine, Gary!  You would have around 3 dB loss in a two-way
splitter + a SMALL amount of mismatch-loss for the 50-75 ohm mismatch. I
would expect that if your radio will work with the beverage signal, you
won't likely need the preamp to make up for tha very modest loss from the
splitter and the 75-50 ohm mismatch!  Should work fine!

Can anyone point me to a design for a splitter for sharing a Beverage
antenna between two receivers?  This is for Field Day so these are not
optimized Beverages by any means.

Just want to allow the 80/40M stations to share antennas.  Nothing fancy.

My thoughts are to just use a CATV "2-Way" splitter at the output of the
Beverage matching transformer and run separate feed-lines to each radio. 
I'm pretty sure these things work down to 1 MHz but have not measured them.
I can use the pre-amp in the radio (K3) to compensate for the loss.

Thoughts?
