            ANTENNA PRODUCTS CORPORATION LPH-9/30/24

            GENERAL DESCRIPTION


            ROTATABLE, HORIZONTAL POLARIZATION, LOG PERIODIC - LPH-9/30/24

            photo Antenna Products Corporation LPH-9/30/24 Applications

            The LPH-9, LPH-30, and LPH-24 rotatable log periodic antennas provide excellent reliability in medium to long rang HF communications circuits.

            Features

            The rotatable LP has high gain, azimuth selection, high power capability and allows communications between a fixed station and mobile stations such as ships, aircraft, or tactical deployments.

            Characteristics

            The antennas consist of tubular step-tapered aluminium elements and a horizontal aluminium boom supported atop a galvanized steel rotating mast. The twin-guyed galvanized steel towers restrain the mast laterally. A base-mounted rotator supports and rotates the mast and array. A rotary joint allows continuous rotation.

            Equipment Supplied

            Array, mast, twin towers and guys, rotator remote control, rotary joint, anchors, and erection kit without winch.

            Optional Equipment

            Obstruction lights, ladder climbing devices and winch. Coaxial cable, connector adapters and mating adapters. Computer controller with RS-232 interface.
