While Bird does not make a "Sitemaster" (their device is called a Site Analyzer), Jim is correct on what it can see. My Anritsu SItemaster (S331A) can see the stainless steel clamps used to hang Heli
Jim: Assume you are interested in the weak signal portion of the band below 51 MHz. I have a Cushcraft 5 el 6 meter beam that is over 45 years old and still working fine. Mine has one piece elements
Jim: I have a bunch of L5PDF connectors. N Female premium connectors. They sold. for $131. The non-preimum connectors were about $35. $10 each, plus shipping, Less if you want a bunch. Also have some
Dave: The AM station may have been using a folded unipole antenna which looks a lot like detuning wires. --Mike, WV2ZOW _______________________________________________ _______________________________
While all the gap type suppressors will protect the amp just fine, the input of the rcvr is going to have over 1000V across it before the gap fires. while a 1/4 wave coaxial stub is a bit long to be
Yes. I ordered an antenna over the winter (InnovAntennas product). I told them I would not be putting it up until spring, to take their time. It arrived about a month ago. --Mike, WV2ZOW ____________
I can't seem to find any 20G pricing (which makes sense, as it isn't current production). I'm curious -- how much cheaper was 20G vs 25G? --Mike, WV2ZOW ______________________________________________
Another perspective: Years ago, my company built a tower in Ohio. Land owner asked that we put a beacon on it. Our regulatory compliance group (lawyers) advised us to NOT light the tower, since FAA/F
First, try FCC program TOWAIR. Its free. http://wireless2.fcc.gov/UlsApp/AsrSearch/towairSearch.jsp This tells you if you must register your antenna structure with the FCC, which means you need to no
Bill: I felt the same as you for the longest time -- I resisted Powerpoles. Ring terminals work just fine. That's until a friend was using them exclusively, and I would bring some of my stuff to his
I expect generics to show up soon. TYCO has a compatible connector line, and these guys make Powerpole mating connectors: Zhangjiagang Uchen Technology & Engine Co., Ltd. <http://uchen.en.alibaba.com
Eric: Hexacon is still around. Love their irons. The S series is their assembly line industrial grade. These are not temp controlled, but the 60 watt one that takes 1/4" tips will do a fine job on PL
Jim (VE7RF): You are probably correct that latency won't matter, but Jim (K9YC) pointed it out in case it could be an issue. In recent years, FM stations have been simulcasting, and to do that requir
Tom and Grant: I do not believe the AVA style comes in 1/2". LDF4-50A is still available. LDF5 and above has been discontinued. 73, --Mike, WV2ZOW _______________________________________________ ____
Julio: 400MAX and Bury Flex are pretty similar cables. Both polyethylene outer insulation. 400MAX has a larger center conductor (10GA) vs Bury Flex 9.5 GA. 400MAX has a slightly less dense foam. One
Bill: How about Anodizing? If not a choice, it should at least make the list. --Mike, WV2ZOW _______________________________________________ _______________________________________________ TowerTalk
Perfectly clear. However, would the same math apply if the pair of cables were treated as a shielded balanced line? I could see some applications for that. --Mike, WV2ZOW ____________________________
David's method of using a topo map and sighting an object is the best way. A GPS requires it to move in order to get a bearing, and magnetic compasses have issues. Besides the difference between magn
If the gain is at the expense of the UP or DOWN direction, it is generally a benefit. --Mike, WV2ZOW _______________________________________________ _______________________________________________ To
John: The LDF cables are great performers. The AVAs are also good, but use less copper and are a bit more fragile. RFS has comparable products as well. There is an overlooked manufacturer -- Trilogy
