problem is that I plan on employing it on the same mast with the
transmitting antenna. Is that bad practice? The reason is that I am
not allowed an outdoor antenna, and I live in a small flat.
ER... um... maybe. Even Wellbrook says one should
locate it away from strong transmit antennas to
avoid overloading the receiver input.
I think the correct answer is that it all depends
on how well you isolate the receiver input from
the transmit antenna and whether or not you use
a separate receiver from the transmit radio, and
similar considerations. SO2R installations have
similar issues - sometimes guys use a "front end
protector" as is reviewed in QST this month, and
other guys use a "time sequencer" to kill the \
antenna when transmitting, tied to the PTT line
and still others use a separate receive-only
antenna input on the rig, as is available on the
Omni VII, but not the Eagle.
Yep... This COULD be a serious concern if not
fully thought out.
BUT YOU COULD TRY IT AND SEE HOW YOU LIKE IT
AS A RECEIVE ONLY ANTENNA AND DEAL WITH THE
TRANSMIT LOGISTICS LATER...
Then, I'll think about the antenna. I've already started to look for a
frame for the loop - I'm thinking 3/4" pvc; and flexible copper tubing
for the main loop.
I know SWLs often use hula hoops ...
