This amazing piece of robust engineering is at the heart of all our huge and powerful EIRP systems. We stack the 1kW amplifiers up like Lego bricks and they operate day in, day out 24/7 without batting an eyelid. Strong and robust is an understatement to the physical construction and RF performance of these amplifiers. 1kW is a typical power level for signal penetration of buildings in densely constructed cities
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 1000W 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
The power output of this model is 1kW continuous day and night non stop 24/7. It has reflected power protection and it has over temperature protection. In the event of any of these protections being activated, the power will reduce to a safe level to prevent any damage. When the fault that triggered the protections clears, the power restores automatically back to full.
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.
High Stability
Regardless of high temperature, high VSWR poor antenna and mismatch conditions or poor AC power, the power level of 1000W 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
This product's AC version is truly versatile and can be used with any AC outlet globally, accommodating a voltage range between 90 to 260V and at 50 or 60Hz.
Antennas
The model will work with our 50 ohm antennas listed below:
Vertical 5/8 Wave
4 Way Stacked Dipole
8 Way Stacked Dipole
Circular Dipole
Folded Dipole
