A couple of things to consider:
– The RSP1A is a wideband receiver
– The maximum continuous input level is 0 dBm (10 dBm intermittent)
– The maximum power input is at any frequency (not what RSP1A is tuned to)
You are probably running a linear and you will have a lot of gain on the DB36.
The continuous power input to the RSP1a will depend on the Tx power level, mode (USB, AM, RTTY, FT8 etc), the path loss over 100 feet and the off band response of the OB16-3.
It would take a lot of testing with different bands and modulation modes to determine if less than 0 dBm was present on the antenna output going to the RSP1A.
So you need to consider one of the following…
One is to get a MFJ-1708B SDR switch which isolates the RSP1a whenever you transmit.
The second is to use a Rx protector box to protect the RSP1a. You can build one or buy one of the commercial units from Array Solutions, DX Engineering or other vendors on the Internet.
