Receiver Guard RG5000HD Electronic RF Limiters are the best choice of inline devices to protect your receiver antenna inputs.

The Receiver Guard is a receive antenna input limiter specifically designed to protect a sensitive receiver front-end against high levels of RF and potential damage.

At the heart of each Receiver Guard is a highly effective electronic RF limiter covering 500 kHz to 150 MHz with an insertion loss under 0.15 dB up to 50 MHz and under 0.30 dB up to 150 MHz.

The multi-stage design includes a gas discharge tube for maximum pulse energy protection.

What happens if the receive antenna is extremely close to the transmit antenna, or there is an antenna support or other system failure that causes a high RF level to enter the receive antenna input? A Receiver Guard can save the day!

Features

• Keeps stray high levels of RF from damaging your receiver input
• Ideal for separate 160 and/or 80 meter receive systems with large pulse and RF energy capture area
