For responders in hard-to-reach areas, we offer the 2AR3A booster and antenna as a low-cost solution. The Alerter is ideals for retained firefighters who are primarily based in RF unfriendly situations, such as metal warehouses or areas of high interference.
The Alerter works in the same way as a regular 2A, but its signal capturing abilities are enhanced by a fixed antenna. This antenna can be placed outside, as fully waterproof, with the Alerter kept inside (stationary) to receive a shout as normal.
