Diamond WD-330J

The Diamond WD-330J is a complete antenna built to professional standards. It is a Wide band 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-330J is constructed from vinyl coated  #14 copper wire and has an intermediate insulator cover protected with epoxy resin..

Antenna consists of :
S0-239 type connector, 2 x Insulators.

NOTE: WD-330 is the same antenna but with coaxial supplied.
