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)
Pros
- 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
Cons
- 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
