Marine AntennasMA 160-Ex

ATEX certified, End-fed ½ λ dipole marine and base station antenna for the International Maritime VHF band in Hazardous areas

Description

MA 160-Ex/... is a 0 dBd, vertically polarized, omnidirectional marine and base station antenna.
Models within 154 - 162.025 MHz.
Full-size, end-fed ½ λ, black-chromed stainless steel whip.
Before installing the antenna, read the ATEX Product Manual carefully.
The antenna is suitable for use in gas groups IIA, IIB and IIC in zone 2.
The antenna can be mounted on threaded 1" water pipe using the supplied 1" revolving nut. In this way, a nice, slim installation is obtained.
A wide variety of accessory mounting hardware (see below) gives ample choice regarding alternative ways of installation.
All metal parts in the antenna are DC-grounded. Consequently, the antenna shows a DC-short across the coaxial cable.
The antenna is a ½ λ design and this means that it needs neither loading coils, ground-plane, radials nor other auxiliary arrangements.
