Flex 8400M Transmit / Receive Path Separation

Question: transmit on your main antenna and simultaneously use RX-A. Does the 8400M provide adequate safeguards that protect the RX-A from being overrun or damaged? Use case: use a Loop for RX-A and main TX ANT 1 (BTV6 vertical). Approx 30 ft apart. Any preamp settings to consider. Thank you. 73's

Here is a link to a worksheet that will allow you to assess the danger quantitatively.

I have a loop on ground antenna directly under my end-fed long(ish) wire and beam at 50 ft. I have the LOG on RXA and the other antennas on ANT1. I run 500 W without ever having seen the ADC overload message, so I am guessing that you will be OK with your set up.
