Hi Gary,
The most efficient way to share a Beverage among two (or as many as four)
bands to use W3LPL bandpass filters. Loss of each filter is in the order
of 1.5 dB vs. about 3.5 dB for a typical Magic-T combiner/splitter.

Just connect the inputs
You might find this of interest, the magic-t combiner/splitter:

I use a couple of old CATV splitters for general purposes around here
and can't measure any excess (more than 3 - 4 dB) loss from common to
either port.
If you want a known good design to build some of your own, try:

One word of caution, Gary, if the CATV splitter is a transformer type,
rather than resistive it may of have enough low-frequency response for 160
m! Check around with RS and your local electronics stores for 50 ohm 2-way
splitters. Those are generally resistive and have frequency response from DC
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
split
I've used a video selector box (for 75 ohm RF, with F connectors) that
Radio Shack used to sell. It was a 4-in 2-out matrix, and allowed either
of two radios to have any of the 4 available antennas. It also allowed
two radios to share an antenna simultaneously. I doubt R/S still sells
it, but t
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" sp
