The HD 2 A is an active crossed dipole receiving antenna providing a large bandwidth and dynamic range for the medium- and short-wave bands.
It covers the frequency range from 1.5 MHz – 30 MHz.
The small dimensions and associated low weight make this antenna ideal for both stationary - where space is at a premium - and transportable applications.
The system can be extended to a receiving antenna system for vertical and horizontal polarization, if necessary also subsequently, by combination with an active monopole (e.g. STA .. A/. /. /0.01-30).
The antenna amplifier for the horizontal dipole is installed in a watertight and seawater resistant cast aluminium alloy housing, the antenna head. The antenna rods are made of glass fibre reinforced plastic fitted with stainless steel screw connections.
The cable connector is 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.
Regarding the robust construction and the use of weatherproof materials our active antennas can be used under extreme environmental conditions.
The nominal operating voltage for the antenna is 39 Vdc. The AAN power supply series or an aas.tech Antenna Distribution System is used to feed the operating voltage to the active element via the coaxial cable.
Customer requirements can be considered on request.
