Universal HF VHF DX WideBand Preamplifier 1-200MHz T-R Relays 2000W-1500W

Enhance your reception with Universal HF VHF DX WideBand Preamplifier 1-200MHz T-R Relays with transmitting capability through the preamplifier up to 2000W.

Usability:

• As a super low noise, unconditionally stable preamplifier for low-gain antennas like Beverages
• Low noise preamplifier for HF Upper Bands in bad conditions on 15m or 10m with transmitting capability up to 2000W
• 6m Low Noise DX preamplifier for contesting, DXing, or EME up to 1500W
• 4m Low Noise DX preamplifier up to 1500W
• FM DX Low Noise preamplifier in the range 88-108MHz. To improve the reception of distant FM stations
• Airband preamplifier 108MHz to 137 MHz for SDR receivers
• 2m Low Noise EME and DX preamplifier up to 1500W
• SRD or AIS preamplifier 156 – 162 MHz range
• Universal SDR preamplifier 1 – 200 MHz range for HF-VHF
• Maximum power on HF 2000W
• Maximum power from 50MHz to 200MHz 1500W
• SO239 or “N” connectors by order
• Fail-Safe relay option (+12 EUR)
• Outdoor housing (+12 EUR)
• The best use is with the Advanced Sequencer

The nicest thing is the ability to turn off the preamp if needed. In that case, your transceiver will be connected directly to the antenna without any losses. So at any point in the reception, the universal preamp can be turned on or off to check effectiveness and improvements.
