Two antennas

[keithbias1]

Is it possible to somehow tie two antennas together into one scanner. So if I want to monitor two different frequencies I can use two different antennas on one scanner?

Do a google search on "diplexer" and select one that has the frequency split and connectors you need.

It mostly depends on the frequencies, if they are in the same band or in totally different bands.
You can use a low-pass filter and a high-pass filter from Mini-Circuits if the frequencies are
in different bands. https://www.minicircuits.com/WebStore/RF-Filters.html

just get a tri band scanner antenna and be done with it. Most scanner antennas are broad band and will work just fine. There is no need for multiple single banded antennas and trying to figure out how to connect them all together for a scanner.
