Do not leave the RV3 permanently connected inline between your dish and receiver. Continuous exposure to outdoor elements will degrade the internal circuits and attenuate your everyday viewing signal.
The RV3 is designed for temporary outdoor setup use during dish calibration. It is not waterproof. Do not leave the meter permanently installed inline outdoors, as rain moisture will destroy the digital circuitry. deutsche technologies rv3 digital satellite finder manual
