To inject a comment, with all respect for Field Day activities, these
represent operation over a few hours as compared to those of us that use the
same antenna or group of antennas day in and day out over a year or two. I
really don't believe that operation in a "foreign" location with a "new"
antenna is solid basis for antenna performance evaluation.
This is contradictory to the reference that Pete provides regarding the
Hattiesburg ARS results. To that end I give more credit to the skill of the
operators with regard to FD scores.

> Stuart, we have also used low horizontal loops for FD - and I think we
could have gotten an award for WAA. Worked All Alabama - or Arkansas - or
Louisana, Georgia, west Tennesse, and the Missouri bootheel. And not a lot
else on the wires. And it's really hard to share a tribander between CW and
SSB stations.

impermiable clay, where conductivity is officially 2ms and usually measures
less than 1. That surely accounts for some of the difference.

Vee's or "half rhombics." Of course they are directional but not so
directional you can't cover North America with three antennas. The first
year we put a pair of Vees and a dipole up for FD at my farm we placed fifth
or sixth in 2A, which isn't bad considering the shortage of operators.

operators we had, we always placed quite well. Whether the ionosphere
cooperated or not.
