Please, pretty please, change the subject line to grounding or something. ;)

Now I know what all of you are thinking. FCC FCC FCC >JK> fact is, that FCC guidelines say no more than 36 dbm coming out of your >JK> antenna at the cell site. That is why you use an omni 8 or an omni 10. >JK> With 10 ft of cable and a couple of connections you should be right on >JK> the FCC guidelines.
