If you analyze your listening habits, you’ll find that you may spend the majority of your time listening to either the 136-174 MHz VHF high band or the 430 – 470 MHz UHF low band. But this compromise delivers mediocrity: meaning it can receive everything, but does a lousy job doing it. An antenna that can receive anything sounds like a great idea who wouldn’t want just one antenna to pick up every signal under the sun. They are designed for portability and to receive the widest range of radio signals. The stock antennas that come with your handheld and base scanners are considered compromise antennas. Here are three tips that will help you continue to receive a top quality signal for your radio scanner. Since the radio signal takes up less spectrum, it also becomes weaker and harder to receive. Narrow band signals already sound quiet on older wide-band scanners, so compounding things with a weaker signal to start really doesn’t make for a good scanner listening experience. Narrowband channel spacing allows the FCC to put more radio signals into a given range of frequencies. By this year, just about every public safety radio system has made the transition over to the 7.5 Khz narrowband channel spacing.
