The Diamond WD-330 is a complete antenna built to professional standards. It is a Wideband folded dipole ( the same type used by the Military for frequency hopping) and is designed to operate from 1.8 MHz to 30 MHz continuously with SWR below 2:1 For transmitting the antenna can be matched on any frequency down to 1:1 SWR with an external ATU - but on the Amateur bands this should not be needed. This antenna is power rated at 150 watts PEP and can be installed in horizontal form (flat-top), in "V" inverted or inclined with the lower end fixed to within 02m from the ground. The Diamond D-330 is constructed from vinyl-coated #14 copper wire and has an intermediate insulator cover protected with epoxy resin.

The antenna consists of an S0-239 type connector, 2 x Insulators, and 30 m of top-quality co-axial feeder cable (5D-2V) with fitted PL259 plugs are all included in the kit.

NOTE: WD-330J is the same antenna but without coax supplied.
