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 50W 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
The final output section of this model uses a MRF151 rated at 150W. This MOSFET RF power transistor is designed for the toughest engineering environments and has stood the test of time and can survive severe load mismatches, short, open or any phase angle of VSWR. This model runs the MRF151 at only 50W which means it run forever without any failure. The amplifier can be set at lower power levels, right down to 10W if required.
High Stability
All our transmitters and amplifiers remain stable in power and spectrum purity regardless of VSWR mismatch, over temperature, incorrect supply voltages etc. They will work in hostile climates and still remain within the International Telecommunications Union (ITU) standards at all times.
Global Voltage Compatibility
The AC version of this product is genuinely universal and can be used with any AC outlet worldwide, supporting a voltage range of 90 to 260V at a frequency of either 50 or 60Hz.
Antennas
The model will work with our 50 ohm antennas listed below:
Vertical 5/8 Wave
Single Tuned Dipole
2 Way Stacked Dipole
4 Way Stacked Dipole
8 Way Stacked Dipole
Circular Dipole
Folded Dipole
