[Elecraft] Isolation between Ant 1 and 2??

[DOUGLAS ZWIEBEL]

Do not assume that this entirely due to "poor isolation."  Much of it
probably is, but not all.

I remember about 40+ years ago, hearing a friend on 15m on a "dead"
band.  He was only around 2 miles from, but he was really weak.  I
called him.

Turns out, he was testing on his DUMMY LOAD.  No second antenna port
(his was a Galaxy V Mk II).  Obviously, the dummy load was not "total
isolation."  Or if it was, then the coax going to it was not.  He was
using a Heath Cantenna.

How many others have had a QSO using their "dummy load" or were able
to hear other stations while using their "dummy load?"  How many have
tried?

An easy test would be to keep the DL connected and disconnect the
other coax from the rig.  Then calculate the difference.  My K3s only
have Ant 1, so not possible to try here.
