[Hi-zreceivingarraydiscussions] Grounding the feedline when Hi-Z is "on"

[Lee K7TJR]

At this time Ken that is not a good idea. What happens is the array picks up
your TX signal and then the 75ohm preamp tries to drive the dead short with
that large signal. It fries the preamp when powered up.

>From Ken Case K5KC
 
Finally, after 26 months, I turned on the Hi-Z 8-circle array (160M) this
evening.  My situation is a little different from most:
 
900 foot run from base to Hi-Z field.
Using Green Heron base and remote box to select direction of Hi-Z.
Running a single RG-6 coax from base to Hi-Z field; no control lines.
Using a deep cycle 12+ volt battery with solar charger at the center of the
Hi-Z field to power the Green Heron and the Hi-Z which are on all the time.
All seems to be working well.
 
Now, the question.  I also have two sets of Beverages.  I use an  antenna
switch to feed one or the other into the K3 as a receiving antenna, used  in
diversity mode.  I'd like to add the Hi-Z 8-Circle coax to the switch so  I 
can select the Hi-Z or either of the two Beverages to feed to the K3.   BUT,

the switch grounds every antenna not selected, so if I were to select, say,
Beverage 1, then both Beverage 2 and the Hi-Z 8-Circle feedline will be
shorted  to ground.  Is this OK or not? I know shorts in the Hi-Z lines to
the amps  are not allowed when the Hi-Z is on, but what about the feedline?
 
Looking forward to your answer.
 
73, Ken K5KC
