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.
