Antenna Tuning Units (ATUs)
Antenna Tuning Units
Including Indoor and Outdoor Aluminum Cabinets, Pre-Fabricated Buildings, Mockups for existing buildings, and safety screens.
Kintronic Laboratories, inc. LTU-series of Line Terminating Units (Antenna Tuning Units) are configured for typical installation at the base of an AM/MF tower radiator. Each Line Terminating Unit (Antenna Tuning Unit) is custom designed to provide a wide band impedance match between the characteristic impedance of the transmission line and the drive impedance presented by the tower. Typical LTU/ATU utilizes a “T” network design. RF Components are conservatively rated for the required transmitter carrier power (1KW to 1MW+) plus 125% modulation resulting in long term reliable operation. Kintronic Line Terminating Units (Antenna Tuning Units) are configured as Open Panel/Shelf for wall mounting in tuning houses or in a weatherproof housing for outdoor installation. Higher Power Line Terminating Units (Antenna Tuning Units) can be supplied in complete mock up form for installation in a customer supplied building or shipped in a pre-fabricated building from Kintronic’s facility.
