The Amateur Radio Crossword Puzzler

Almanac
It's late spring in North
America and that means it's time to start worrying about whether all those
antenna projects you envisioned last winter are actually going to get done.
Well, here's a puzzle full of antenna words you can work on while you
procrastinate. Better yet, take it up to the top of the tower, where you get a
little peace and quiet!
When not stretching EZNEC to its computational limits,
Ward Silver, N0AX, authors--among numerous other things--the Amateur Radio
Crossword Puzzler, which appears twice a month on the ARRL Web site. He can be
reached by e-mail at n0ax@arrl.net
or by surface mail at Aetherworks Publishing, 22916 107th Ave NW, Vashon, WA,
