A low dipole - 15 feet average, uneven ground - Receive Only - accounted for something like 40% of the
contacts with NA from XZ0A. During the first 2 hours at Sunset, the low dipole heard signals that the
admittedly not all that good beverages could not hear at all.
Great to see so much activity for the Spring Stew. Was sorry to miss it
myself.
The preliminary results are now online:

When I decided on the new challenge of working DXCC on 160 for my ninth band, I
added some extensions on my 80-meter inverted-vee , (apex at 45') and tied them
off on some handy saguaro cacti about head high. You don't climb these :-) I
worked my first 80 or so countries with it. And this is
For those who are antenna challenged, don't sell a 160m inverted-vee at low
height too short.
My 160m antenna at the moment is an inverted-vee at an apex of 45 feet.
Additionally, the last third of each end is at 90 degrees to the main
portion and horizontal at only 7 feet or so off the ground.
Inverted vee dipoles do produce some vertically polarized radiation off the
ends. However, that vertical component has maximum gain at zenith, i.e.
straight overhead. It does not contribute to any significant low-angle
radiation. You can see this by doing an antenna model.

Hi Ed,
I've studied this extensively for horizontally polarized antennas, but
only for flat ones; I thin that inverted Vees have some vertical
components.
For horizontally polarized antennas, maximum gain at high angles occurs
at a mounting height of about 75 electrical degrees, and falls
I was reminded of my interest in re-installing a low 160M antenna to
supplement by 2 el vertical phased array. And since there was no where to
go this weekend and no College Hoops to watch, I thought, hey, I could get
something up and play around with it in the Spring Stew. And that what I
did.
A couple of issues I see. It depends which direction(s) the noise and
desired signal are coming from. You may null the noise and signal.
Also, the loop is bi-directional.
I've been playing with a DX Engineering RF-PRO-1B at ET3AA and it
works. Thanks to Tim and the gang for their support. But
