Active / Passive Receiving Antenna 1.5 - 30 MHz

Horizontally Polarized Dipole and Monopol


This antenna is applicable for the reception of the short wave range (1,5 – 30 MHz) on board of naval ships. It consists of a horizontal polarized dipole and a horizontal polarized monopol. Both antennas can be either operated in active mode (optimal sensitivity) and passive mode (optimal immunity).

The small dimensions and associated low weight makes this antenna ideal for both stationary - where space is at a premium - and transportable applications.

Active / Passive Receiving Antenna HD 1 A/P - HA 1 A/P


The antenna amplifiers are installed in a watertight and seawater resistant cast aluminum alloy housing, the antenna head. The antenna rods are made of glass fibre reinforced plastic fitted with stainless steel screw connections.

The cable connectors are fitted to the bottom side of the antenna head's bottom flange. It is protected against the environment by means of a trumpet shaped mounting support (the funnel) which is mounted to the bottom flange of the antenna head. The opposite end of the funnel fits the size of 2" supporting pipes.

The output impedance of the antenna is 50 ohms, so that even long cable lengths between the antenna and receiver can be used

With regard to the robust construction and the use of weatherproof materials our active antennas can be used under extreme environmental conditions.

The operating voltage is supplied to the active element through the inner conductor of the coaxial cable from the power supply and control unit AAN 300. On failure of power supply the receiving antenna is automatically switched to passive mode, so that the receiving operation further maintained.
