Dana Rawding asked:
> 1) How do you account for a log periodic?
Easy...how many elements were you USING? Multi-band L-P's are typically viewed
as 3-element beams, right? The "most resonant element" + the "one behind and
one in front" is the rule of thumb.

Easy...the ARRL rules already address this. See "ARRL Rules for VHF Contests",
Rules 2.1.1.1 and 2.1.1.2.
> 3) How do yo account for dishes?
This will require a little thought (especially since it's also possible to use
feedhorns, etc). But this seems like a minor wrinkly. The base-concept is
sound.

Because it complicates things too much. Keep it simple and give people some
wiggle-room in how they choose to participate and compete.
2x 13-element beams and 160 watts puts me in the High Power class. Do I want to
piddle it away with RG-58/u or will I feed my antenna with LDF7-50?
