200 Watts with a high performance well installed antenna is a typical set up for a local radio station for a big town or small city. In rural areas up to 40 miles range is posssible.

The internal 200 watt amplifier blocks will operate with ease at full power 24 hours a day non stop in any country and with any AC voltage in the world. The front panel of this tarsnmitter has a neat little meter panel lit up with intense blue LED's to indicate forward and reflected power. The RF output power of the amplifier automatically folds back to a safe level when there is fault condition of poor SWR and return loss of any level for any duration of time. When the fault clears the amplifier restores to full power.
The 200W power amplifier was designed to be stacked in our 3200W ERP system, but customers emailed, telephoned and asked if it could be purchased alone without the system, the answer is now an absolute yes. The amplifier will deliver a minimum of 200 watts of robust stable power from only 1 watt of drive with low harmonic and spurious levels below -75dBc. To the best of our knowledge this satisfies the legal requirements for all countries in the world. This incredible RF gain provides amplification of 23dB (200 times!!!!) without a single instability.
Unlike other power amps on the market, this unit is complete, tested and ready to use on delivery. The internal power supply accepts 90 to 260V AC making it suitable for use in all countries of the world. Just hook up the power amp to your antenna, transmitter drive and mains power supply. Never take off the lid, no tuning needed, no test equipment required. This unit is truly plug and play. It is suitable for use with all our 1W drivers and possibly other manufacturers 1W transmitter drivers, you would need to check this with us.
Under severe load mismatch conditions (poor SWR, Return Loss) the amplifier will automatically foldback the power to a safe level to protect itself, the antenna and cables from damage. When the load becomes good, full power automatically restores.
The circuit design is over engineered using a 150W MRF151 device, this ensures extremely reliable safe operating levels for the power amp. Careful design of the RF output stage matching provides very efficient DC to RF conversion allowing the amp to run very cool in the worlds hottest climates 24 hours a day, every day, every year.
We are primarily engineers with a passion for radio, not sales people. If you have any technical questions please feel free to email us.
On delivery the equipment is ready to plug in and use with any suitable 50 ohm antenna system such as our Vertical 5/8 Wave, Single Dipole, 2 Way Stacked Dipole, 4 Way Stacked Dipole, 8 Way Stacked Dipole or Circular/Mixed antennas.
Our 500W ERP, 800W ERP and 1400W ERP packages include this amplifier complete with antennas and cables ready to go. All are full systems that comply with the regulations of the European Union and most other countries in the world.
This FM amplifier system along with all our other products comes with a limited 2 year warranty (see warranty conditions)
All our models comply with European standards ETS 300384 for R&TTE, EN 301 489-11 for EMC and (LVD) 2006/95/EC for safety, the relevant FCC sections of US 47 CFR Part 73 for verification and ITU-R BS.450-3 (11/01) FM Broadcasting at VHF.
We are absolutely passionate about the products we build and we try and think of everything we can do with our designs to make it easier and reliable for the customer. We are not the best sales people, but we are great engineers, so if you have any technical questions please feel free to email us.
