[Elecraft] K3 KRX3 ANT

[Don Wilhelm]

Evert,

Yes, I believe using the AUX RF BNC is the preferred solution for your case.
If the main receiver will be on a lower frequency than the sub, the low 
pass filters will be set for the main RX/TX and would severely attenuate 
the higher frequency input to the Sub RX.

It may make your external antenna connections or switching scheme a bit 
more complex, but it is one of the compromises that one must make when 
tuning different bands with one transceiver.
