Yep...center pin migration due to extreme temps happens with these connectors. But, the biggest issue I've seen with mil-spec type N's are their incorrect installation (both in the government and civ

I found a link for what seem to be decent crimped N type connectors with captivated pins. They're made for most of the Times LMR series, as well as the RG-8 variety. You would need the proper crimp t

All: Someone mentioned weatherproofing RF connectors, despite their inherent characteristics (N type vs. UHF). This sounds like good advice to me. Personally, I like to use Scotch 70, a self fusing,
Hi Michael, You could cut off a couple of feet from each end and still be ok, I believe. You could also check the cable with a megger, a piece of test equipment that measures feed line insulation res
All: If I'm not mistaken, the megger won't generate more than 500 to 1000 volts with VERY little current. If the coax can't handle this basic leakage test, it's trash. If memory serves me right, the

N2EA is right. Lightning protection shouldn't just rely on the tower base's UFER ground according to NFPA and UL industrial comm. site requirements. In new construction, the rebar cage in the tower's
Hi Dan, You may consider a penetration and pvc that size, but I would include a single point grounding plate mounted in a weatherproof fiberglass Hoffman box. In turn, this box would be mounted over
Check out the Max Gain Systems "Antenna Mart" webpage: http://www.mgs4u.com/catalog/ Specifically, the tower insulator kits for Rohn 25 & 45G sections. http://www.mgs4u.com/catalog/page11.htm They lo
I thought there were safety issues concerning the use of stainless bolts on towers due to their lowered tensile strength and the possibility of them shearing? Is this true, or a wife's tale? Can an e
Yep, the B&W antenna in question (a terminated folded dipole) is essentially a dummy load with wires attached. 73. Steven Gehring, KZ9G Bothell, WA E-mail: kz9g@arrl.net So it is broadband over dummy
Gee, I was generous... I said in a personal email that the efficiency of the B&W terminated folded dipole was typically between 25 and 50%! It seems to be a bit worse than that. They really are "dumm
All, Can someone please point me to a distributor of quality 4:1 "current" baluns? I'm not looking for the voltage type, but a superior 4 to 1 model that employs two uncoupled cores. I hope such an a
Hi Pat, The only LPA for amateurs that comes close to covering what you're looking for is the 7-10-30LP8 'SKIP LOG' LPA by M2. Here are it's specs: Model 7-10-30LP8 'SKIP LOG' Frequency range 10 to 3
Mega dittos on the DCI filter. My DCI-146-4H is a true, cavity type, band pass filter with GREAT rejection above and below the two meter band. I have the full band model and just love it. Besides the
Towertalkians, I am soon moving to Wasilla, Alaska, which is about 45 miles outside of Anchorage. The home we're buying is on a one acre lot that is approximately 160 by 300 feet. Given the poor cond
Despite the opinions expressed here, are Rohn-like products going to live on? Will they be manufactured again? I've missed that on the reflector... 73. Steve, KZ9G Email: kz9g@arrl.net --Original Mes
Hi Bill, Look at it this way...as a group, we're all getting older and rather crotchety. Sometimes, we all spill comments (from the heart) that would not be spoken out loud. As for Rohn goes, I since
I know someone else mentioned it, but I thought it was worth mentioning again - with a bit more info. AN Wireless is gearing up to make G series sections -- 25G, 45G, 55G, and 65G. See their webpage
