The design drawings call for a rectangular hole with a rectangular rebar cage. An 87 dia hole will be a LOT larger and greatly increase your volume of expensive concrete. I just finished my tower fou

One slight mod on Patrick's feedback... Instead of a rope or stout cable, I would use polyester mule tape (maybe about 1/2" to 3/4" wide) attached to the end of your old cables, so when your old cabl

I have just completed a tower build which took me a good part of a year to do. Last October a rare tornado came through the area and devastated a lot of homes, trees and property. I started wondering

Hi John Yes, one could look at it that way; especially since it didn't cost me anywhere near that number. However, imagine waking up one morning to find the crumpled remains of your tower; one that t

Thanks Gary Since I have another building on the property that could max out the additional structures money available (10% of policy limit), the insurance agent told me to insure that structure sepa

Hi Don I can't provide specific info on adding a 30 foot crank up to your existing base and a section of the old tower. All I can say is that my 72' steel US Tower required 6@ 1" diameter steel bolts
Hello Rich I just finished a crank up 72 US Tower install this Spring. I have had no interference at my shack which is about 25-30 from the tower. I learned quite a few lessons from this install. Som

Hello Bob I've got a 73' crank up tower and have thought about that, too. I guess it depends on what failed. If the motor just died, you could, of course, clamp the coupling shaft and then replace th
Chuck I was worried about the same thing when I put up my crank up tower, but the rock was crumbly enough I was able to get down 8.5. (The following thought is not based on any engineering calculatio
Chuck - I dont know if the explosives comment was tongue-in-cheek, but I think I would stay away from explosives. The last thing you want to do is loosen the soil surrounding the hole. Besides the we
Yes, that is correct. If you have enough cable, Id feel more comfortable, though, with 3 wraps. Make very sure that the end is secure and clamped down. Also, pay close attention to the location on th
One more item I should mention... it is always preferable to use commercially swaged aluminum crimps on wire ropes than rely on hardware store U bolts. I once had a business that manufactured dumping
Just a comment about Up The Tower by Steve- I am so glad I bought that book before my tower installation. Besides all the advice he gave, he also gave the pros and cons about getting a permit from th

Paul Since I only have a single 73' tower, maybe I don't understand the need to run out into a storm or the night to look at your antennae? Can't you just tell by your SWR meter and pumping out a few
