hopefully someone can help me. Here it goes. i have a discone base antenna and also a nmo moile to base antenna mounted mounted on the roof. I own a taxi company in nj along the shore so reception shouldn't be a problem right?? wrong!! the discone when hooked up to my bc780 receives fine. the problem i'm having is the "commercial" nmo mobile to base antenna hooked up to my cdm1550 at my dispatch desk. the "commercial" antenna is about 35 feet high and picks up very faintly. and the repeater i use is 8 miles away. mind you that the antenna mast is grounded.. I also get a little shock on the connectors of the coax. There is a computer and cable modem in the area of both radios. does anyone have a clue whats going on?? i tried to elaborate as best as i can. any help would be appreciated!!
