I use this same antenna and it works great. I pick up everything in my area with ease.Got to say that I just bought a Radio Shack Outdoor VHF-Hi/UHF Scanner Antenna
20-176 Catalog #: 20-176
Outdoor VHF-Hi/UHF Scanner Antenna - RadioShack.com
I am about 50 miles from DFW airport, using a Uniden BCT15x. With the included back of the set antenna I got almost nothing out here in the country-- but with this little antenna I pick up DFW and many other long range frequencies. AND the antenna is setting on top of a tripod inside and not yet mounted outside! (as a test) I have no idea what I will pick up once it is properly mounted outside.
Very good antenna for $30. I would buy a proper outside antenna like this one -- and not use that CB antenna.
