[Elecraft] [K3] Sub-receiver with one antenna jack

And I'd expect NO penalty for sharing the same antenna except, perhaps, on 6
meters. The K3's noise figure is already quite low. Indeed, watching the
e-mails posted here, it seems that a lot of K3 owners fail to turn on the
attenuator on the lower bands and some even run the pre-amp which degrades
the receiver performance even though it makes the bands sound "louder".

The subrec includes an aux antenna jack (BNC) so you will still have
possibility of two antennas.  There is also the REC antenna on the KX3Va
module (if installed).

I have a fairly bare-bones K3, ie no provision for a 2nd antenna and no ATU
installed.

If I install the sub-rx, what is the penalty in terms of MDS due to the fact
that both 
the main and sub rx will share the same antenna?

Thanks/73,
