Basically this is a typical drawing of connections between transceiver and antenna in case of use the LNA (Low Noise Amplifier).
The first one is the 144 MHz set-up. Use the transceiver and LNA without power amplifier.
We used:
-one coax cable
-2 coax relays
-an antenna
-a LNA
-a transceiver
On this picture you can see the 144 MHz set-up with power amplifier. This one is good for EME and MS operation.
We used:
-two coax cables
-2 coax relays
-an antenna
-a LNA
-a transceiver
You also can use this set-up for 432 MHz band. For 23 cm band I recommend use this set-up.

I need 2 of your pre amps, with out relays. 144mhz and 432MHZ
