AD-52

The antenna AD-52 is a wideband wire directional antenna intended for use with handheld or manpack radio units in VHF frequency range from 30 to 88 MHz. The radiating element is made of wire with special capacitive loadings along it, enable together with antenna matching transformer very low VSWR and on the other hand directional radiation pattern and therefore relatively high gain. The antenna is mainly intended for use in stay because of its simple construction and easy erecting . Except of the wire radiating element the antenna is composed of matching transformer unit, watertight enclosed in a fiberglass housing with all necessary connectors, the 15 m long coaxial feeder made of RG-58/U with coaxial connectors, lifting rope 25 m with weight, anchor and hammer. All together is packed in a handy linen bag, suitable for transport.
