What is the drive from the HL2 without the onboard PA activated? I know it is a very low level output but I don't remember if it is adjustable. You may not need a t attenuator if the output is sufficient.
Hi Joshua
When the HL2 onboard PA is not enabled, there is NO RF output on the ANT output connector, the ANT connector becomes a RX input connector, and the RF1 connector is the only RF output, 17dBm, from the HL2. RF1 is OUTPUT only so I would still need relay(s) to switch the antenna between RF1 for transmit and ANT for receive, and I'm not sure that RF1 is variable RF level (or indeed low pass filtered).
Thank you Joshua for taking the time to try and help me, really appreciated.
