Here is the WA2SRQ data from my personal archive ... -- Having access to a Hewlett-Packard 4193A vector impedance meter at work, I have made measurements on a number of baluns, coaxial and otherwise.

Two or three of the TV broadcast towers in Miami came down during Andrew. I know the WTVJ (then WCIX) tower came down on top of the transmitter building trapping a couple of engineers for a couple d
On the other hand, the AN tower has sufficient capacity to be useful in high windload areas (like Florida, coastal Carolinas, etc.). Even the heaviest Trylon towers are not spec'd for a big tribande
I have to step in here as Force 12 is getting a bum rap. The C31XR appears to work properly "out of the box" if one is installing it in the single feedline mode (as it was designed). Bob 5B4AGN has i
Carl, I can echo Hasan's comments ... Look into a log periodic as an option. I won't deal with a specific choice of brand but I have run models for a couple of the 18 foot, eight or nine element LPs.

Even 1996 is recent in the attendance slide at Dayton. Having been there every year from 1970 through the mid-1990's (before the move south), the decline really started in the early to mid-1980's. I
Just about anyone in the television industry will have problems with the May dates ... they're right in the middle of the "Sweeps" and most stations will not allow time off for news and/or engineerin
The handling of side mounted loads depends on the nature of the TOWER SYSTEM. If one is dealing with a free standing tower, the failure modes are either due to side loads (wind) or crushing (total w
Fred, Doesn't "annoyance" give some overly zealous architectural review committee an opportunity to declare a tower "offensive" or a "nuisance?" Wouldn't a simple prohibition of commercial structures
AO tells me that the capacity hats on the D-40 (or 40-2CD) shorten the element tips by about 26 inches. Ran my D-40 (40-2CD) driven element model with and without the capacity rods ... and the tip ha
Paul, You're only partially correct (if I may argue with a lawyer on a legal issue). If the laws concerning Homeowner Associations (or private contracts) permit actions which are unconstitutional ..
Paul, That's exactly the point ... when the HOA steps into areas that are traditionally the province of government (e.g.. freedom of speech, due process, regulation of interstate commerce, land use,
Mick, Please send a copy of that document, if you still have it, to the ARRL. It would be a perfect exhibit for the effort to have congress enact invalidate anti-tower, anti-ham CC&Rs. Lest anyone h
Perhaps a more appropriate action is to go back to those same state legislatures that have adopted PRB-1 type "reasonable accommodation" language and ask them to extend those statures to apply to pr
You are correct, Steve. The old Hy-Gain design used the standard driven element insulators in the clamshells of the 402BA but placed the linear loading between the feedpoint and the elements rather

Back off the attack level just a bit. Although some homeowner associations are serious about enforcing their CC&Rs, "homeowner association nazis" is unnecessary ... and I'm offended by it. In case a
