Of course, one could argue that amateur radio towers is a first amendment and separation of powers issue. The federal government has authorized us to operate an amateur radio station and no other go
Not necessarily so. I know of several people who had absolutely no idea the property they were purchasing had CC&Rs until they were presented the documentation at closing. In most cases, the CC&Rs a
There is a very large and powerful National Association of Home Builders ... the housing industry trade association ... and any move to weaken CC&Rs would certainly run up against them. ____________
Yuri, You made an assumption about the configuration under discussion (as did Tom). The original poster did not specify if the unused 1/4 wave wires were grounded or floating (the switch boxes Tom de
Dick, Certainly the common failure mode of commercial towers (other than intentional sabotage) is failure of one member (either vertical or horizontal) which will result in a crumpling or crushing fa
Lest anyone doubt the weight of TV antennas, here is a fragment of e-mail from my former Assistant Chief Engineer in Huntington WV. He was updating me on the digital tower project that started some f
FCC and FAA regulations tend to limit commercial towers to 2000' The FAA will, almost as a matter of course, find any tower greater than 1000' a "hazard to air navigation" and the FCC's ERP vs. heigh
Tom, Since I'm planning an antenna installation I did some modeling of a Cushcraft D-40 (half a 402CD) at 60 feet over poor ground (Diel Const = 10, Cond = 2 ... sandy Florida soil) vs a four square
Since the original question concerned a move from 50 to 100 feet, in my experience a single 10 Meter antenna at 100 feet is almost always too high to do much good. With a single (multi-band) antenna
Guy, You missed a key piece of information ... The FCC standard is 120 *HALF WAVE* radials for AM broadcast. 1) it maintains the .02 wavelength separation at the ends ("dense" radial field) 2) it pr
Don't take "leaving the amateur market" too literally. I spent some time talking with my contacts at Will-Burt on Monday (my business is a large user of their pneumatic mast product). WillBurt are si
I can vouch for the problem with Netscape 4.7. I keep a copy on my systems for two reasons ... to access the FCC ULS and to check HTML (web source code) before releasing it on some of the sites I hel
Nathaniel, Many years ago when I was in Columbus my studies indicated one wanted to be around 50 to 55 feet for reasonable minimum performance on 20 meters (I don't believe one gets enough bang for t

Check the "NAB Store" www.nab.org and the Society of Broadcast Engineers www.sbe.org. Both have generally had similar signs for use around broadcast facilities. The signs are not exactly inexpensive,
How true ... I vividly remember a phone conversation with a tower vendor (and regular advertiser on TowerTalk) in which I asked for 100 MPH specs on his towers (both extended and retracted). He comp
When major portions of the country is in other than 70 MPH wind zones, it would make sense to do at least sample calculations for 80 and 100 MPH (or 110 MPH) wind zones. Manufacturers of guyed and f
I have dealt with Will-Burt Manufacturing for nearly 20 years in the broadcast business. They build nearly all of the pneumatic (microwave) masts used in live broadcast vehicles, emergency light "to
Knowing the people, process and product at Will-Burt, I know they will produce a quality product as long as there is a market and it is profitable for them to do so. The real question is whether Fir
