Antenna loop Connections

I have a very fine Clifton Labs Broadcast Band reject filter I'd like to use with my 6500.

I'm assuming that I can just install it in the Antenna in/out loop, and make the appropriate configuration choices.  But never having used such a setup, I'd like to be certain that I can transmit normally using the antenna with the loop enabled without causing damage to either the radio or the filter.  The block diagram seems to say OK, but I thought I'd ask.

Also...are the RXA in/out ports 50 ohms?

Jim:  I use a BCB filter on my 6700 - Yes insert it between Ant x OUT and IN, where x is the antenna port of your transmit antenna.  For a RX only loop, I use a Pixel, inline the filter with the RX loop and connect to Ant x IN.

With the first example, "Loop X" may be selected to insert/not insert the BCB filter.
FYI - Ant 1 OUT is the RX only presentation of Ant 1 antenna

Thanks!  As I indicated, this is a new area for me, and I didn't want to let the smoke out!

Thanks, Tim.  Good information...as you know, the in/out impedance can be important for these passive filters.
