Hi .. is there a trick for pulling in what is (probably) a low power T-band frequency? There's a frequency in the 470-512 range a business uses for mobiles that I can't pick up at home (probably 10 miles distance as the crow flies). I'm thinking they are using low power because I only pick them when I'm probably within 1-2 miles of the place. ... Would a T-band antenna (470-512 MHz) make any difference? ... I really don't have the option for an outdoor antenna. Thanks for any info/tips etc.
