AD-52 ANG NL.cdr - Trival Antene

AD-52The antenna AD-52 is a wideband wire directional antenna intended for use with handheld or manpack radiounits in VHF frequency range from 30 to 88 MHz. The radiating element is made of wire with specialcapacitive loadings along it, enable together with antenna matching transformer very low VSWR and on theother hand directional radiation pattern and therefore relatively high gain. The antenna is mainly intended foruse in stay because of its simple construction and easy erecting . Except of the wire radiating element theantenna is composed of matching transformer unit, watertight enclosed in a fiberglass housing with allnecessary connectors, the 15 m long coaxial feeder made of RG-58/U with coaxial connectors, lifting rope25 m with weight, anchor and hammer.All together is packed in a handy linen bag, suitable for transport.Frequency rangeImpedanceVSWRGain (vs. 1/4 l)3 dB beamwidth azim.3 dB beamwidth elev.Front to back ratioPolarizationMaximum powerConnector typeMass of antennaAntenna lengthMounting heightTemperature range30 - 90 Mhz50 ohm< 1.88 - 11.5 dB90 - 30 °35 - 10 °> 13 dBVER.50 W CWFME +N, TNC, BNC,3.8 kg17.8 m8 - 10 m-40....+70 °CTRIVAL ANTENE d.o.o., Gorenjska c. 25, 1234 MENGES,SLOVENIA; tel. +386-1-8314-396; fax. +386-1-8313-377email: info@trivalantene.si; www.trival-antennas-mast.com
