[TowerTalk] Introduction

[Steve Maki]

Gary-Joe,

I'd say 99.5% of the installed 50 ohm hardline base (by footage) is 
copper. Commscope tried their darndest to introduce their smoothwall 
hardline (both copper and aluminum) to the cellular industry, but it 
never caught on. One reason was that when you cut away the jacket to 
install a ground kit, smoothwall cable becomes very fragile - not so 
with corrugated.

Commscope eventually gave up on that and purchased Andrew.

Of course smoothwall 75 ohm was always the standard in the cable TV 
game, where they never needed to remove jacket except at the connectors.
