• Low Distortion Analogue Linear modulator Amplifier.
• SO259 Aerial Socket on rear of unit
• average 25W RF output (100W peak) into 50 Ohm load
• 1024 to 1638KHz selectable from rear panel (max 1740KHz)*

25 Watt AM Transmitter for Short Aerial
£260
A High-Power version of AM Transmitter, operating between 540KHz and 1700KHz in the Medium Waveband (AM Band) and feed a short Aerial simply by adjusting the output Tuning control. No need for any external Aerial Tuning Unit (ATU)
Broadly they can deliver up to 30 watts of power into a short length aerial. This equates to 100 watts peak power cleanly driven up to 100% modulation.
20 Watt High Band AM (Discontinued)
£
A High-Power version of AM Transmitter, operating between 1024KHz and 1630KHz (1740max) in the Medium Waveband (AM Band) and are designed to be reliable and stable units.
They can deliver up to 20 watts of RMS power into an aerial of 15 to 25 metres. This equates to 80 watts peak power cleanly driven up to 100% modulation.
This transmitter has been designed to operate into a fairly short ‘long-wire’ aerial, minimum length approximately 12 metres and up to 25 metres. No additional ATU is required.
