Why settle for a weak signal which can produce image glitches or broadcast outages? The Alcad CA-340 amplifier solves this problem for you. It can handle connections of two UHF antennas, which can be pointed in different directions or have different polarizations. The level of amplification is adjustable for all inputs The amplifier is housed in a ZAMAC casing which boasts excellent shielding effects. It is also resistant to interference from LTE transmitters.
