HIGH GAIN 50W/250W AMPLIFIER, DESIGNED FOR DIGITAL TV

Designed for very low power digital exciters, this UHF amplifier offers very high gain in a compact, well ventilated, RF isolated and practical aluminum enclosure with integrated mains power supply and control circuitry. All this at a reasonable price. Finally a solution for digital TV that will not break your bank. This UHF amplifier uses super-linear NXP fets for distortion-free digital signal. This module is also ideal for bringing the exciter power high enough to drive stronger digital TV UHF amplifiers. 

Technical specifications: 
- Mains power: 110-240V (50/60Hz) universal input, mains cable not included (same as used for PC)
- Frequency band: 470-850 MHz
- 66dB gain max. Automatically adapts to exciter level.
- BLF881 50volt LDMOS Technology.
- Input/Output 50 ohms, N female connectors
- Pout: 50W max / 250W max
- Weight: 10Kg

Advantages: 
- Accepts signal from exciter and adapts gain automatically to prevent overdrive
- Excellent performance at low cost
- Stable well shielded design, required for such high gain
- Compete plug-in solution with integrated mains power supply
- Simple to use, just ON/OFF button
- LCD display, adjustable output power

Limitations: 
- it is recommended that you also specify frequency so that we can set power meter to show correctly at the chosen frequency.
- band pass filter/cavity filter not included (recommended)

IMPORTANT:
- Due to the high gain of this amplifier some shielding between exciter and antenna is required. WPlease ensure your antenna is well away from the amplifier and the exciter. This means at least 5 meters, preferably on the roof many meters above your work area.
- Excessive drive level can damage this amplifier; it was designed to work with low level exciters
