[PVRCNC] 15 meter SS propagation

[Jim Jordan, K4QPL]

If you're HP, and only using 2-el wires, I don't think I'd bother with a 
second one. Actually, a "lousy" beam aimed WNW is best for SS. The multi 
element stacked arrays, etc. are great for DX, but a liability in a domestic 
contest since you've got a very broad azimuth of say 240 degrees here in NC 
for potential callers. You don't need a perfect signal to a narrow beamwidth 
unless you're trying to break the pileup on a VY1. Generally what you want 
is a "good" signal everywhere in the US when you're running. Ty, K3MM, 
actually uses a low dipole on 20M as an alternate.

I've found the VE7CA 2-el wire beam just skews the circle somewhat to the 
west and redirects just some of the RF that otherwise would be departing 
towards Howie and across the Atlantic. This weekend I was switching between 
my TH7 at 70' and the portable tribander strung up about 40'. To everywhere 
but the far west, Pac, AK, the 2 el was often better and did fine to NE 
without having to turn a rotator. The take off angle is probably higher.

I'm not a guru and haven't run modelling patterns, but this little creature 
cooks! It's hung to aim WNW and really works into everything from TX to MN 
but is "bad" enough that it's more like a dipole in other directions. With 
QRP I worked the Pr and Vi stations off the back that would have been 
difficult from the TH7 without turning it.

I also found on 40M I picked up a couple db by switching between two dipoles 
at about 60' hung about 90 degrees apart favoring N-S and E-W.

Hope that helps.

73,

Jim
