COMSYSTEMS Antennas AD-2/WB-7 represent the family of transceiving self- supporting HF wideband
monopoles. The antennas are composed of three sections, connected together by screwjoints, protected against unscrewing with cross screw protecting unit. The first part of the antenna is support with antenna matching unit underneath. Inside the base is the matching circuitry and (optional) GPS antenna.
The N-type connector is mounted on the side of the antenna base. The support flange is convenient for mounting directly on deck.The antenna sections are made of epoxy-glass composite material and the screw joints
are made of stainless steel. The antennas are very lightweight but on the other side they are highly resistant against all weather conditions. The flange on the support type is made of special polyamide and aluminum with excellent mechanical characteristics. COMSYSTEMS Antennas AD-2/WB-7 are intended primarily for use on all kind of ships, oil rigs etc. They could be also used on ground objects for stationary use. In that case a special wire ground-plane must
be ordered. NO ATU needed. This antenna will work without using ATU. It is meant to be connected directly to an HF radio .
