AA-7 HF/VHF/UHF Active Antenna


AA-7 HF/VHF/UHF Active Antenna

Construction KIT - $35.00 (Temporary out of stock--do NOT order!)




Features:
  • Simple 9V Alkaline battery operation.
  • Replaces a 60 feet long-wire antenna.
  • Amplifies signals from 3 to 3000 MegaHertz in the HF, VHF, and UHF.
  • Selector switch for VHF/UHF.
  • If you have a shortwave or high-frequency receiver or scanner that is struggling to capture signals with a short, whip antenna, and you'd like the kind of performance that a 60-foot 'longwire' antenna can provide but lack the space to put one up, consider building the AA-7 HF/VHF/UHF Active Antenna described in this article. The AA-7 is a relatively simple antenna that is designed to amplify signals from 3 to 3000 MegaHertz, including three recognized ranges: 3-30Mhz high-frequency (HF) signals; 3-300Mhz very-high frequency (VHF) signals; 300-3000MHz ultra-high (UHF) frequency signals. Those bands are typically occupied by shortwave, ham, government, and commercial radio signals.
