Aramid does not stretch. I have never noticed fiberglass to stretch either, except perhaps when I am cornering at the limit in my Corvette. :) 73, Keith NM5G --Original Message-- From: towertalk-boun
Fiberglass may be sensitive to UV, but I doubt it affects strength significantly in tower guying applications. However, I also prefer the light weight and easy storage of Philly and would not conside
Do you know of anyone who experienced a failure after the rod was installed? If not, there is really no issue here as it has been stated before that the manufacturer replaced failed coiled product. 7
One could think of an object here on Earth as an antenna receiving energy from the sun. Since the sun is transmitting about 4 × 10**26 watts, it is not difficult to understand why that Al plate
According to http://www.tennadyne.com/ the company is for sale. I remember hearing a couple of years ago the original owner wanted to retire. A friend here in the Houston area purchased a T-10 about
I have many F12 beams and have never found any insect nests inside the boom. 73, Keith NM5G Hi, I just put together the Force12 WARC 7. There is no end caps for the boom ends nor for the ends of any

I need some help with phasing two antennas in a stack. The antennas are Force12 C-3 and C-4XL. The C-4XL is essentially a C-3 with 2-el added for 40M. Since element spacing and feed method (current b
Thanks Bill. This is the kind of info I have been looking for. 73, Keith NM5G NM5G: phase angle in degrees, then add the appropriate amount of coax to offset the difference. Stacking patterns are not
All, I think I have found a workable solution. My initial plan to add a delay line to the C-4XL will likely eliminate the phase difference. The delay line will be 70 inches (about 6 feet), which is 8
Who cares? If you want a modern, good performing tribander, you should not be interested in this antenna. Seller thinks it is worth a small fortune, and it may be to a collector or diehard KLM fan. I
gain is pointed. And for that phase errors do make a difference. Whether it's important is another story. You bet it's important for DX contacts. 73, Keith NM5G ______________________________________
I would expect problems with the SteppIR at only 5 feet separation. My experience is that 10 feet is usually required to reduce mutual impedance to a tolerable level. 73, Keith NM5G I am getting read
Two sides to that coin. If you send goods before receiving payment, don't moan if you don't get timely payment. If you wait for payment before shipping goods, consider the other party is taking the f
Galvanized u-bolts are nice, but hard to find. Would they work for this application? 73, Keith NM5G --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-bounces@contesting.co
I carried a Pyropen on the flight(s) from Houston to Falkland Islands and back in checked luggage last November. Was told not to charge it with butane but did anyway without consequence. 73, Keith NM
Got all mine from Texas Towers. 73, Keith NM5G I am looking for Big Grips (Part Number BG2144) for 1/4" EHS. Any good sources or alternatives? Fred Mott, AB8AH _______________________________________
I have obtained a roll of 3 inch copper strap (Polyphaser) and want to use it to build a new SPG and tower ground system. I will be using 8 foot copper clad ground rods. Where does one get Cadweld ma
Sounds bogus to me. I had a tower mounted next to the house slab and bracketed to the eave. That tower was struck multiple times without any adverse effects. 73, Keith NM5G My attention has just been
Think of your roof as an extension of the ground. Keep your antenna about 1/2 wavelength above the roof to keep ground losses and elevated pattern to a minimum. 73, Keith NM5G Hi Guys, One question I
