Dunno for sure, but think it's cuz it's time for refuting industry submissions. Simple reply time is over :o( 73, Dave, N3HE Yes, I have the same problem. What can we do?? 73, Dick WC1M SNIP
Hi, all concerned: What's the buzz on the ARRL antenna course? I registered immediately after it became available, but, due to time and other constraints, haven't taken it yet. If there're 'peer revi
Time permitting, I'll wind some coax on a 20-ft 2.5-in-dia stick of munimula this weekend, test it, and post results. I'll guess ahead of time that the L and distributed-C of the braid and to the boo
Hi, all concerned: I'm looking for 24 'tower legs': 1. Material: galv-after-fab. steel, or s/s 2. Length: 4-5ft 3. Dia.: 1in -to-1 1/4in. 4. 90-deg 3in-long bend one end, "std" thread for at least 8i
Thank you all for the snappy replies. It was asked, What am I looking for? Stuff out of which to make a support for a turntable, so I can rotate an 'amateur antenna support structure' from its base.
Hi, all concerned: I need a complete copy or original of a no-longer-available Heights catalog from the '80s or so which includes all the dimensions, weights, etc., of towers with 30-inch face width
Source of (600 or any other Z)-ohm owl? Why sure. Any generic 'hardware store' has all the #14 or #12 copper wire I've ever needed, and I buy those telescoping fiberglas poles and cut 'em up for spac
Do any of you TT'ers out there have a short (3 or fewer reasons) pro/con on whether the 'technical excellence' found in Antennex makes the subscription is worthwhile? Despite the well-known, widely-r

Hi, Todd: When you're up in the air, and want to use h-f, one easy-to-write/say solution is to engineer the station so that it has odd quarter-waves of conductors in two (preferably pi-radians apart)
Hi, all concerned: Givens: 1 CC X7 1 old rebuilt CC A3 1 80-ft strong-enough tower and mast 100 ft from houses, trees, other clutter 1 40M old rebuilt HyGain 2L shortie with coil loads at tower-top p
BIGSNIP Brilliant! Just trust Tom that dielectric in the coax doesn't contribute to losses. Some "evaluation" of Force 12 products. Yuri ADSNIP Hi, Yuri: I have difficulty following your posts, becau
.. did we hams overlook hi-tech levitation/anti-gravity as antenna supports? Were we too busy in the simple-electro-mechanical-solutions world? Should we go along with all these green-card tech-nerds
I think it goes this way: Circles and lambdas have 360 deg. each. One percent of 360, or 0.01 of a lambda, is 3.6, which translates to about 100 radials. A radial every 0.025 lambda, or 8 deg, would
Build a form around it and bury the post in a yard or 4 of concrete. Fill the post, as well. 73, Dave, K3BHJ List Sponsored by AN Wireless: AN Wireless handles Rohn tower systems, Trylon Titan towers
.. on behalf of an elderly ham friend in the greater-Baltimore area. If I were there, I would do this myself. 30-odd years ago, I put up a TRISTAO telescoping 50-ft rotating steel pole, HAMM-M, coax,
Hi, all concerned: I'd buy another reasonably-priced KW MatchBox today. Offers? Years ago, I made a Trash7 drive the bejeebers out of a Honky 2K (3dashfourhunnertzees), by putting a home-brew pi-type
