I was the one who convinced AT&T to accept heat shrink in this region. 
Previously butyl and vinyl tape was the only accepted method, but it was 
a nightmare on panel antennas with closely spaced connectors.

However heat shrink is not fool proof either. Use a little too much heat 
at the edge of the shrink tube and you compromise the coax jacket. Use 
it up on the tower in high winds and it's difficult to apply *enough* 
heat. It takes some practice to get it right. So it's not a matter of 
simpler - it's a matter of choosing a method that works for your scenario.

I was really just commenting on your apparent belief that other methods 
are inherently not as good as heat shrink tube, which just isn't so.
