You and I had the same idea. Here are photos of both ends: http://www.dutson.net/Ham/P6160004.jpg http://www.dutson.net/Ham/P6060006.jpg Keith I have a couple of underground 2" sechedule 40 electrica
There has been a lot of talk about lightning protection. Seems each person is satisfied with their setup for protection, or the lack of same. And there are many testimonials to back up the claims. We
Regarding unhooking the coax connectors, take a look at the following excerpt from the Polyphaser engineering notes at http://www.polyphaser.com/ppc_PEN1016.asp: -- Just a word to those who tell us t
before that, before the storm arrives. I don't get it. Exactly what is bleeding off before the storm arrives? Keith --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-boun
Thanks for the detail. That makes sense. I made a similar observation on my tower but not with a meter. The hair on my head stood up! :) I believe charge transfers such as this have been well documen
I would make the earth connection when not using the switch. The Ameritron 5 pole switch that I use has an option to ground each pole when not energized. All you do is solder a jumper for each relay.
I agree with this assessment. My club has a 2 meter repeater located on a tall building in Houston. The antenna sits on top of the building, mounted to a metal facia running around the perimeter of t
Indeed, you may have stumbled upon the loophole for those living in a home controlled by HOA/CCR. "But sir, it is to protect the bomb in my house from lightning." <grin> Keith WD5CXL Considering the
What is the best method to tension the guys? There is 6700 pound Phillystran at 150-113-76-38 feet on Rohn 45. TIA Keith WD5DXL _______________________________________________ See: http://www.mscompu
Thanks Steve. The Phillystran is terminated with big grip/thimble and shackled to 1/4 EHS. The short EHS (10 foot) has grip/thimble on each end with turnbuckle attached to elevated anchor post. So, i
I have one of those in the PVC pipe. It will get first use this weekend as a test before taking on DXpedition. We are going to hang a dipole from the top. The sections are friction fit, so will need
Half wavelength is standard for optimum coupling, or about 10 feet for 6 meters ((6*39.4)/(12/2)). Keith What would be a starting point for stacking 2 6M7JHV 6 meter yagi's? Thanks...Rich ___________
May be, but I have always heard 1/2. Anybody out there with experience? How does spacing affect take-off angle? Keith Isn't maximum gain somewhere in the 5/8 - 3/4 wavelength range? 73, Pete N4ZR The

If you think about it, losing a bolt from a tower leg is not really a big deal. The weight above is more than sufficient to keep the section in place except perhaps during a tornado, and then it woul

Jim, Being able to discern a target signal from a group is quite subjective. The top contesters can complete a contact that others could only dream about. They often put one in the log that was cover

I saw that on the news this morning and figured it must be a joke. Or, maybe the political news is getting so stale that they dreamed up another sensational story. :) AFAIK it takes about one million
