Whether you need a temporary means of transmitting announcements or a low cost, rapidly deployable package for disaster relief teams, the AmpliVox All-Weather Hailer does it all. The entire system contains a communication case and a set of speakers that can be easily transported and set up by one person. All electronics are housed in a rugged, sealed, fully weatherproof carrying case. Use your own 2-way radios (2 are needed) or the AmpliVox MURS radios for the communication devices. One 2-way radio acts as the receiver and is located inside of the weatherproof case connected to the external antenna and speakers. Using the other 2-way radio as a microphone, you can transmit messages up to 2 miles away. The rest of the system consists of a flex antenna, rechargeable battery, integral charger, a 110VAC power supply, and a separate PA horn / speaker assembly that attaches to an aluminum contractor grade, wide frame, extension leg type tripod. Multiple stations can be setup throughout an area and activated simultaneously as a group.
