[amsat-bb] RX-only Antenna "tee" connector?

Hi everyone.

I suppose that any deviation from the ideal setup of a near-perfectly matched antenna & receiver will have SOME negative effect, but for a receive-only antenna, how badly am I hurting myself to split the antenna between two receivers?

Since frequency is probably important to answer this, I’m referring to 70cm.

Also, if it matters, I have a very good preamp (SP-70 from SSB) at the antenna feeding 25 meters of LMR-400.  Both receivers are SDR devices (receive-only).

When I tested against a 70cm beacon, there was some small reduction in signal strength but it wasn’t much.  With voice, you might not notice but my interest is telemetry data.

Thanks for any recommendations or experiences with a similar arrangement!
