I have a TE Systems repeater amplifier, and receive is attenuated when the amplifier is in line versus when it's not in line.

Is this normal since the amplifier has no relays to take it out of line or should it not be attenuating the received signal strength?

Yes, This is exactly what will happen
The amplifier is designed to go to the
output of a transmitter only. What you
would have in a repeater, separate units,
NOT a transceiver.

You need to either use a different amp or 2 TR switches.  Think of an amp as a pump with a check valve.  When it's off, the RF won't go back the other way, so you need 2 TR switches to bypass the amplifier when receiving.
