[TowerTalk] OT. FS Tower & Coax Grounding-Sealing Kits

[Steve Maki]

2-1/4" Heliax. We installed a bunch of it on cell sites, but the 
customers finally figured out that it was overkill. Bump the TX power up 
a bit if you like, and install TMA's (tower mounted pre-amps) near the 
antenna for Rx noise figure purposes, and save tower lease cost by 
reducing feedline weight and windload.

Of course there exists much larger coax mostly found on high power FM 
stations and VHF/low UHF TV stations. Higher channels will be waveguide.
