Hi I have just purchased a base scanner (Commtel COM205) once I got it all set up I was given a Realistic Pro 2042 with aerial, I have also ordered an MRP-2000 MK2 pre-amp, I am a little bit akward as I would like to connect everything up as follows,

2x aerials into coupler then into the pre-amp, split out of the pre amp into the two scanners,

I dont know how fussy the scanners and pre-amp are with relation to impedance/ load so I would like to draw on everyones vast knowledge and seek advise.

Thanks

Steve

That lot should work fine as long as you use proper diplexer for the two
antennas(why two antennas though? are they for different bands??)

and just a normal antenna splitter from the amp to the radios

use 50ohm cable, splitter and diplexer and you'll be sweet

I was thinking about using two different antennas as They are different styles and I guess they will have different "sweet spots" thanks for your info I think I might just swap between the two antennas until I decide which one is better.

Thanks

The best option is to have an antenna for VHF and one for UHF close to
your favourite bands, this way you have max signal for your favourite
stations and they will still work fine for the rest
