HF Active Antenna
Active HF antenna for HF3/W and HF3/P SSB receiver. Supplied with 7 metres of cable.
Note – if your HF3 receiver has a red couloured label on the rear chassis the power supply for the antenna is already built in. It is activated by the slide switch on the rear.
If your HF3 has a black coloured label you will need the optional antenna power supply here:

Coaxial cables are vital to the performance of your antenna and radio system. Selecting the best coaxial cable has become more and more complicated as more suppliers are offering a broader range of products. The cable selected will affect the system’s cost, coverage and reliability. That’s why for our antennas we only use one type of coaxial cable, the TOP PERFORMANCE RG 58 CU MIL, designed to guarantee the best signal transmission.
H Vector Navtex Antenna
Conventional navtex antennas respond to the electrical component associated with the navtex radio signal. They usually perform well at sea where electrical interference is low but can sometimes be overwhelmed with interference especially when in harbour and connected to shore power.
In most small craft the electrical system acts as an effective ground for the antenna but it can also be a source of interference conducted from other electrical equipment on board. Electrical interference can result in poor reception especially in a marina where the ambient level is high or at sea when poorly suppressed electrical equipment is in use.
The omnidirectional H-Vector antenna is not sensitive to electric fields but to the magnetic component of the navtex signal. As a result it is less sensitive to locally generated interference and, as it does not need a ground, it is not affected by conducted ground interference whether in harbour or at sea.
The net result is that, under adverse conditions, the H-Vector antenna can deliver a significant improvement to navtex reception. The mushroom shaped antenna is compatible with the Clipper navtex, series 2 Target navtex and with the navtex engine. It can be mounted on a cabin roof or rail mounted using an appropriate threaded antenna base.
