    ...by the Federal Communications Commission (FCC) and use ultra high frequency (UHF) and very high frequency (VHF) bands. UHF radios use line-of-sight communications and repeaters. They provide better reception than CB radios, which can use either HF 27 MHz or UHF...
  • Frequency Meters-Image
    Frequency Meters - (113 companies)
    Frequencies in the middle of the range equalize the currents in the two coils and allow the needle or pointer to indicate the midpoint of the scale. Changes in frequency create an imbalance between these currents, causing the coils and the needle...
  • Frequency Counters-Image
    Frequency Counters - (137 companies)
    Frequency counters are designed to work on a wide range of radio frequencies. If the frequencies are very high, the frequency counter uses a high speed prescaler that reduces its frequency to operate digital circuitry. Specifications of a Frequency Counter...
