Receiver Front-End Protection
Picture: R.L. DRAKE company
The RP-500 Receiver Protector offers receiver protection necessary to allow operation in close proximity to high-power transmitters. The solid state circuitry furnishes protection to all RF signals, even those in the microwave band.
With the RP-500 the receiver is protected at all times, even when in the off position or tuned to other frequencies. The protector is inserted in the transmission line between the antenna and the receiver and limits the signal level applied to the receiver while providing very low insertion loss under lower signal conditions.
