100 watts is the most popular power level for broadcasters and regulators across the globe. With the right antenna you can cover up to 45km (30 miles). Since the late 90s we have have sold these everywhere for many functions, not just broadcasting. Some countries still use some frequencies on the broadcast band for signaling and things like that. What is common to all customers is that we ship these and never hear anything from them again, unless of course they want to buy another.
1 Watt Drive (can be more on request!)
All our amplifiers use a standard input of 1W. This means for 1W of drive power this amplifier will produce 100W of RF output 24/7 whilst maintaining international technical standards.
If you require a different input power level, no problem, we can do that easily. Just email or message us in the box below for more details.
Temperature Resilience
It doesn't even get hot, well, maybe a little, this is because it's got two strong fans on the rear of the unit which keep the internal temperature at very low levels, even when the ambient temperature is up at 40C. So basically these will work anywhere on the planet. The circuit design is over engineered using a 150W MRF151 device, this ensures extremely reliable safe operating levels for the amplifier. Careful design of the RF output stage matching provides very efficient DC to RF conversion allowing the amp to run very cool in hottest climates 24/7. The super silent version has much larger internal heatsinks with very slow and gentle fans than make less noise than a whisper. You can see the video demonstration of this below.
VSWR Resilience
Under severe load mismatch conditions (poor SWR, Return Loss) the unit automatically folds back the power to a safe level to protect itself, the antenna and cables from damage. When the load becomes again, full power restores automatically and instantly. The front panel has a forward and reflected power meter, so you can monitor the state of your antenna all the time.
Super Silent ADDED Option
What is SUPER SILENT? it means it's as quiet as a mouse and can use it in a live mic studio without background noise. The video demonstrates the 100 watt transmitter, but it is exactly the same for the 30 and 50 watt units.
If you want SUPER SILENT option, MAKE SURE YOU ADD IT AS AN OPTION in the price panel below.
SUPER SILENT means less 20dBA, this is comparable to a low level whisper in a studio, the chances are other equipment, air con or studio ventilation is higher in volume.
High Stability
Regardless of high temperature, high VSWR poor antenna and mismatch conditions or poor AC power, the power level of 100W will remain stable all the time and the RF signal will never pollute the spectrum with instabilities. The output amplifier in this unit is designed to work in hostile conditions and environments. The BBC, British Army and US Army Delta Company all purchased these units for use in Iraq and Afghanistan.
Global Voltage Compatibility
All AC version of this product is truly globally compatible, you can plug it into any AC outlet in the world from 90 to 260V at 50 or 60Hz
12V and 48V DC Option
The regular version of this unit is 90 to 260V AC. However we can also manufacture it for 12V or 48V DC. To the best of our knowledge, in the entire world, Only We Make 12V DC FM Broadcasting Transmitters and Amplifiers up to RF Power Outputs of 250W.
Applications include mobile setups where only a car or vehicle battery is available. We have a perfect Magnetic Mount FM Antenna for mobile setups. Also fixed installations with connection to solar battery systems of 12V and 48V DC
We default ship the AC version. If you want the 12 or 48V DC version, it's important you notify us by email when you make your order.
