Navtex receiver
Shortwave receiver
The Magnetic Transfer antenna is the first rod antenna in the world with wideband coverage (0.5 - 30 MHz) without an antenna tuner. The antenna is only 2 metres long, and 32 mm in diameter. No radials are required. Reception pattern is omni-directional and the polarisation is elliptical, which
reduces polarisation fading. The antenna is passive, so no intermodulation products are generated and overloading by nearby transmitters is impossible. The receiving element, a helical in the "normal" mode is grounded and the received signals are transferred only by a magnetic field. Thanks to this Magnetic Transfer technology, MT antennas are much less sensitive to man-made interference sources such as computers or fluorescent tubes, compared to normal rod or whip antennas. Coaxial lead-in cable to the receiver. Heavy-duty construction. The special version for the Global Marine Distress & Safety System (GMDSS-NAVTEX) delivers a twice as strong signal on long- and mediumwave as the standard MT version. In the shortwave bands the signal level is nearly equal, but above 25 MHz the GMDSS version delivers less output compared to the standard MT version.

The GMDSS - 2 is the smallest passive wide band antenna in the world. It is only 1,25 mtrs long and neither radials or an antenna tuner is required. Its construction is the same as from it's larger brother the standard GMDSS, but it has a different helical receiving element and associated matching network to compensate the shorter length. The GMDSS is designed for smaller boats, but is also a perfect passive antenna for those living in an apartment with just a small balcony as mounting place for an antenna.
