OlFlex cable from Lapp (http://www.lappusa.com) would be a great choice. I use a 22 conductor to the tower and then a 8 conductor up to the top myself for a small rotator. They offer many different c
That knot was mentioned in a QST not too long ago... Another option is if you see a utility truck somewhere, stop and nicely ask if you could have a couple of grips off the back of the truck... The l
Yes. It's just wire. "Magnet" wire is just intended to be used to wrap stators and rotors in electric motors, or something of the sort. It's usually lacquer coated. 73! -Adam WJ4X ___________________
If it's still working, just take it apart and regrease the ring bearing. I used synthetic wheel bearing grease. Don't loose the balls, and it's pretty straight forward. ______________________________
I buy used Hoffman boxes off "Auction sites" and work around the knockouts that are in there. Just keep looking! I never pay more than $50 for the huge ones. 73! -Adam _______________________________
The Hubbell ones that cover the .400 size are perfect.... If it's really worth being liquid tight, they are the only way to go. $7 each retail is pretty cheap for them actually, I've paid twice that

My 40 HDBX has closer to 6 yards under it. It's a block 6.5 square, 6 ft deep. The old Rohn drawings specified a 4' deep hole. I also have a yard of gravel in the bottom of the hole to prevent ice le

You've never heard of scour either have you? That's basically what it is, except instead of a river eating away at your tower base, you have groundwater doing the same thing... 73! -Adam ____________
This works. http://www.eham.net/articles/23198 I soldered male adapters onto my pipe, and used a hose bib adapter. 73! -Adam _______________________________________________ __________________________
I called and ordered trap caps from Cushcraft and had not a problem. I'd check DX Engineering though... order something better than he started out with. 73! -Adam ____________________________________

Strangely enough, plain old galvanized grey is pretty invisible against a treeline. (Or at least it is from the road at my QTH) A fellow ham here painted his black, and it's somewhat hidden, but the
I utilize a Ufer grounding system here, I have a very heavy clay soil around my place. Some places are heavy red clay. Works great so far :) 73! -Adam WJ4X ___________________________________________
I use these on my tower legs: http://www.amazon.com/Thomas-Betts-Z500-Superstrut/dp/B000GAQEEA Then I use stainless hose clamps to attach the ground conductor to the grounding rods. 73! -Adam WJ4X __
You need to lift up, not pull back. a bobcat doesn't go high enough to create enough angle to lift the tower. Come up with some sort of method to get the hoist cable off the ground. 73! -Adam WJ4X __
