The Alcad FR-619 filter blocks interference from LTE800, GSM and TETRA mobile signals while allowing channels 21 to 60 to pass through. In terrestrial TV installations, it eliminates interfering signals before the TV signals are amplified by the headend unit, providing up to 60 dB rejection in the LTE800 band. The DC pass-through allows a preamplifier to be powered.

The shielded zamak housing is protected by a weather-resistant plastic cover. The filter opens and closes easily, and the frame can be tilted for easier handling. It can be mounted on a mast using a polyamide clamp or on a wall, and is resistant to sunlight and water.
