[TowerTalk] Springs for erecting loops nd dipoles

[John King]

Has anyone found an appropriate spring for protecting dipoles when the supports such as trees sway? Maybe a name hardware supplier has such a spring?

I am going to use Dacron with a strength of about 750 lbs, to suspend the wire antennas, and would like to be able to pull the vertical loop and dipoles strung between trees taunt and at the same time protect the antennas from breakage. I am sure the rope is much stronger than the copper wire that will be used.

The spring must be strong enough to hold the antenna taunt YET give enough to protect the antenna.

I am going to use old water hose on the Dacron where it goes over the limbs to prevent scuff damage to the Dacron. Also, I like the idea of using a weight on the tail of the Dacron near the earth to allow movement of the trees without breaking the Dacron. The weight can be judiciously selected to keep the antenna taunt and still provide give for the line.

Your suggestions will be appreciated. 73, John, K5PGW
