And here I just bought a 500 foot roll of antenna wire which cost a small fortune and was only #14. Roger Halstead (K8RI, EN73 & ARRL Life Member) N833R, World's Oldest Debonair (S# CD-2) www.rogerh

The problem with Lowes and HD are the prices. There are pretty close to 10 times what I pay for graded bolts at the local industrial supplier. I just discovered our local industrial supplier is on li
My preference would be one of the Kevlar based cables which is what I use for guy lines. Although much easier to handle and store, lighter weight, and though they are much easier to damage then EHS.
Yes, it would be nice to use Phillystran or other Kevlar products. But there are two real big negatives that will keep most from doing it: 1. Expense - 1/4 EHS equivalent is 6700, $1.29 per foot, plu
I rented a small back hoe with an operator for a day. He dug three guy anchor holes and carried concrete. Total cost $350 for the day. We did have to reseed part of the back and north yards. I think
The spec. for the foundation for the tower I intend to put up (AN Wireless 60' Light Duty) at this location (80mph winds) calls for close to 10 cu. yds. of 4000lb concrete. The mix itself will weight
For a bit of input: I've installed a few towers and put up a few of my own. A good rule of thumb is the cost goes up exponentially with tower height and load. I've had 40 and 50 foot towers that had

Roger et al: Your photos bring back fond memories (?) of my driving the ground rods into my back yard! Ouch. Thanks. Thanks<:-)) The sand is a great idea. In addition to plugging up the openings in t

Another possibility is to build a small "hutch" to enclose the equipment. Older equipment used to have small heaters that were nothing more than say a 15 or 25 watt resistor under the chassis some wh
If you have the room at the tower you can try what I did. I took mine right up the side of the tower, rotating the antenna at each of the three sets of guys. There are two photos about half way down

It depends on where you live, the climate, the soil, and maybe local regulations. I am installing a 40 foot tower. It will not be self supporting. It will be bracketed to the roof/wall, and I will us
