A long range wireless PA system is used where a wired system would simply be too expensive. The PA system consists of wireless receiver that is attached to a horn PA speaker. A transmitter in the form of a portable 2-way radio, mobile radio or base station intercom is used to send live voice messages directly to the PA speaker from up to 2 miles away. An external antenna can be added to increase range.
The wireless PA does need a 110volt power source, however there is a rechargeable battery pack that will power the unit for up to 10 hours. There is also a solar power package to operate the unit on solar power.
One wireless PA system can support up to 2 horn speakers. These units are available in both UHF and VHF frequencies and can be programmed to work with your existing radios.
This long range wireless PA system has applications for schools, hotels, factories, office buildings, hospitals, airports, marinas, country clubs, warehouses, lumber yards, salvage yards, boat yards, rental yards, parking lots, construction sites, amusement parks, golf courses, special events, sporting events, and lots of other uses.
