As long as the tape goes far enough beyond the end of the Saran Wrap, or Handi-Wrap (TM) to prevent the moisture from getting in I'd say this is probably one of the most durable you will find... as

Why not run the mast through a sleeve a couple of feet long mounted between the tower top plate and a rotator plate below? Actually the sleeve could be much longer depending on what would be conveni

The best stuff I ever used was a self vulcanizing Silicone rubber tape. It came in various widths, but all we had were 1", 1 1/2", and 2". It was tapered being fairly thick in the middle and then ta

Here in the Midland (MI) area it varies by township. In Homer township where I live a building permit is required only if the tower will be taller than 80 feet. They will accept the engineering spec

You sure could. OTOH it's a bit confusing when compared to the FAA charts. There are two very large towers just a bit over a mile from me so they are easy to spot. They are listed at roughly 74 and 7

They may differ slightly from model to model and some may be heavier than others, but when inside I've noted very little difference from the old Ham-M to the Tail twister. Jake has some good advise.

Another alternative is to contain the cable in heavy wall PVC conduit for 20 to 30 feet prior to the capstan. Properly used the capstan is a great device. Imporperly, or carelessly used it likes to
