Hello All, I've got some questions about outdoor antennas. I monitor a
motorola type II trunked system in Colorado Sprigns, CO.

I've got a 20-043 discone from RS, a uniden bcd396t, and 70 feet of
RG-6 quad-shield of cable inbetween. The antenna is on a mast 12 feet
in the air above the house.

Much of the radio communication is choppy; is that a artifact of how I
set up the system? Is this a good setup of cable/antenna/radio? I've
read some information about tuning antennas, but is that something I
still need to do in this case?

Thanks!
