Your opinion on more than one antenna connected to a scanner?

The question was about using more than one scanner with the same antenna. Diplexer was coined. I have what is shown in the pic. Would that work?

That diplexer are used at the parabol dish to connect to one input and a TV antenna to the other input and at the other end of the coax another diplexer are used to take out the two signals, one 950-2000Mhz and one 25-800MHz. When using two scanners with one antenna you will instead need a 1-2 splitter that both port will handle 25-2000MHz with a 4dB attenuation and an isolation between ports of something like 20dB, 100 times.

If one scanner only receives UHF frequencies 250Mhz-1000Mhz and the other scanner only VHF below 250MHz then a diplexer designed for those frequencies will only have something like a 0.2dB attenuation.

I want to also connect two antennas to one scanner using a Diawa two position switching switch but it shows them only going up to 600mgz and I'm listening to 700-800, someone told me it won't pass the 700-800 signal ..?

There are two versions of the Daiwa switch. You want the CS-201GII.

TY, looks like I would have to purchase (3) male "N" connectors to match my pl259 to connect to scanner

PL-259 is not best at 800 MHz.
