Jones); Date: Wed, 18 Dec 1996 09:22:14 -0600; Gents: I saw an elegant solution to how to get a 20-24 foot piece of chrome moly inside a tower. I do it a different way, and have had no problems up to this point in my strategy. I mention it as a p; /archives//html/Towertalk/1996-12/msg00310.html (11,597 bytes)

I modified a Rohn ASx5 rotor plate on my installation to carry a hardwood block for an intermediate plate. The key to homebrewing is your "carefully centered" phrase.

5. Erecting Long Masts (score: 1): Author: ac6ef@pipeline.com (Terry Dunlap); Date: Wed, 18 Dec 1996 19:18:51 -0700; I am curious as to the need to have so much mast buried in the tower. Wouldn't the rotator be just as isolated from side forces with say half as much embedded mast as long as the intermediate support; /archives//html/Towertalk/1996-12/msg00328.html (7,715 bytes)

Isolating the rotator from sideload is important but only a part of the reason. The main reason I like the rotator down 7 or 8 feet from the tower top is a practical one-- yo; /archives//html/Towertalk/1996-12/msg00331.html (8,841 bytes)
