Actually the dangling pull down cable is attached to the bottom of the top section and comes down inside the tower. I lower the tower in 15-20 ft steps and then pull the cable outside the tower at th

A couple of additional comments on tower sections sticking when lowering. 1. My TX472 had fairly tight fitting angle guides on the top section and that was the one which would sometimes stick. I incr

I think your intuition is right Gary. If you think of the tower weight of 400 # being concentrated at the 1/2 height level of 10 ft, there is a leverage situation working against your truck tailgate

Dennis: You will find different opinions here on many subjects however I believe there is almost uniform opinion on guying crankup towers. Don't do it. That puts additional stress on the lifting cabl

Tommy: I am not familiar with your crank up but if it is similar to my TX472 UST you don't have to block each section. I raise and lower mine with a tractor pulling on the single lift cable thru a fl

Bill: I think the pros and cons depend upon the height of tower you are talking about. For towers over a hundred feet or so the guyed tower wins due to much lower cost. The shorter the tower the bett

I am looking for a number of type 31 ferrite cores, particularly the 2.4 OD x 1.4 ID jobs and the large clampons with 1.22 ID opening. I am also interested in any other size type 31 cores. I understa

After looking at the BAMA info on this antenna I cannot tell what type of feed system this antenna uses. It appears that the driven element is split. Does it use some sort of balun or does it just co

Tnx for the FB info on R40G. Passed it along to W6FR who is getting ready to have the crane take down his R40G tower and beam. Too bad no hams are interested in taking down this free tower and 20m be
