Has anyone tried this method?:

Neighbor W6GJB and I, who have worked together on antennas for 10-15 years, have tried a lot of methods. I've used heat shrink selectively to solve specific problems, but not to cover connections completely.

One of the issues with any connection is that we often need to open them up to change something, or to troubleshoot an issue. The method we settled on some years ago is to first wrap the connection with a self-fusing silicone product like Rescue Tape, then cover it with an overlapped wrap of Scotch 88 to protect it both physically and from UV. If we need to open up the connection, we can simply unwrap the 88, then slice the silicone with a knife or razor blade.

This method has worked quite well for us. We do a lot of portable operation in Glen's contesting trailer

and both of us live in the Santa Cruz Mountains, with a lot of antennas rigged high in redwoods that experience storm damage, every winter. And also receiving antennas -- I have two 550 ft long reversible Beverages and a pair of phased VE3DO loops. We've figured out rigging pretty well -- after losing a couple of 120 ft high dipoles in 2006-7, the only ones I've lost since were three that were supported on one end by a 200 ft Douglas Fir whose root ball was pulled out of the ground! The other end of all three dipoles were intact. We rig with weights on pulleys, and rigging is pretty robust.
