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:

Can anyone point me to a design for a splitter for sharing a Beverage

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?
