GuestHi Gurjinder,
Rx-Div and Rx-Main are two receving signals coming from two different branches of the antenna system.
Those 2 signals are combined in the “combiner” in order to provide a “better” RX signal.This is a very typical solution to improve the sensitivity of a BTS.

GuestHi gents
I have a query regarding the FXC E1 and FXC E1/T1.
Our client has a tetra cassidian/ nokia base station. The card used is FXC E1/T1 120 ohm.
Can we use 75 ohm FXC E1 card in replacement of it.
What do we have to do in changing the cables. Will it work instead or we should be using 120ohm FXC E1T1 Only.
