Topband: [Bulk] Re: Outdoor rope suggestions

[Carl]

As I stated when I started this thread about 2 weeks ago Ive had STI line in 
use since 1983 for all sorts of outdoor projects including boom supports. I 
was looking for alternatives and went with Davis Dacron because they carried 
1000' spools; being in the same state cut down on shipping and gave next day 
service. The two brands look identical.

The longest runs these days is to support seperate 160, 80, and 75M inverted 
v's with a common coax feed at 180' with the ends out to 300' or so from the 
tower base. Several pieces are knotted together and takes all that Mother 
Nature can toss at if from ice storms to hurricanes, microbursts, 
N'oreasters, etc.
