Proception 1 Way Power Unit Features

  • Used in conjuction with a Masthead Amplifier to add gain to a VHF Aerial and/or a UHF aerial
  • Used in Poor reception areas where the aerials need to be amplified in order to achieve a clear picture due to:Long distance from the transmitter
  • Interference caused by an obstruction e.g. (hill)


  • Depending on the Masthead Amplifier it is used it can help achieve a 25dB gain which can transform a hazy picture into a clear picture
  • Universal the same power unit can be used with a range of Masthead Amplifiers and Aerials
  • Can be used with power passing splitters to feed a number of rooms
  • Reliable robust unit with high quality low loss f-type connections
  • Less expensive than a 2 output power unit
  • More effective than a using a Distribution system


  • A resaonably high level of experience is required to know how and more importantly when to use a power unit and a Masthead amplifer
  • If used incorrectly or if there is a large amount of background interference a power unit and a Masthead amplifer can actually make matters worse - particularly in a strong reception area
  • Can be a victim of new broadcasts e.g. the new garda radio system can cause chaos with amplified aerials
