Do you have an attic? Had a discone in my attic for years, worked great. attic was about 25' above ground level and was able to pick up Boston From Plymouth mass. That is about 30 miles away. If able to mount in attic I much perfer the Antennacraft ST2 Scanner Antenna. Good luck.
I have a cheap antenna from radio shack on my tower for my home patrol, what would be a good antenna that would work better. Most freq I use are in 155. And 453. Ranges but a universal range antenna would be what I'm needing.
