[Towertalk] Re: weatherproof tape for antennas? (more)

Hi,

Scotch 70 also works quite well.  It's a self-fusing, high temperature, 
silicone rubber electrical tape composed of self- fusing, inorganic 
silicone rubber that provides a waterproof seal.  I also cover it with a 
standard electrical tape like Scotch 33 or 88 or whatever - just to keep 
the dirt and grime off it.  73.
