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
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.
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 b
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 st
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

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 Ma

All the TV splitters Ive taken apart are pure autotransformers with poor isolation. A VNA will show them deterioating and doing very little at 160M. It is simple enough to wind transformers for a spl
Yeah, that's why I cautioned Gary about using CATV splitters at 160m. Seems that he has enough reserve gain with his Beverage and K3, that he could certainly tolerate the loss of a 50 ohm resistive s
Typically the CATV splitters are marked 5-1000 MHz or similar. I've often wondered how much rolloff there was beyond the basic 3-4 dB down at topband. I have a Clifton that I built myself, but have n
People also have to be careful with systems. The "resistor on center tap" splits the signal, but runs the ports out-of-phase. This is OK when you need a 180 flip between port, or you don't care about
