[TowerTalk] Sealing Coax Connections

[kq2m at kq2m.com]

I'm not familiar with White Scotch 88, but I can certainly vouch for 
Black Scotch 88 and Black Scotch 33+ which I use interchangeably on 
everything inside and outside.  In 31 years at my qth with a temperature 
range of -20F to 108 F, both tape has stood up very well to every kind 
of weather plus the UV rays.

Either tape is a bit tough to remove after several years as it gets hard 
in the Winter and a little "melty" at the peak of Summer with some 
condensation underneath the tape, but that's not a problem. The 
connectors are always shiny and bright and the connections unaffected.  
A good sharp exacto knife or boxcutter blade makes short work of getting 
the tape off the coax and connectors.

You can buy these Scott tapes in packs of 10 on Amazon for ~ $4.80 each 
- not cheap but a steal for how reliable it is over time.   Some of the 
tapes are made in Mexico so you might want to buy them as soon as 
possible before they raise the price to recover the cost of the 
imbecilic tariffs.
