The UHF Wireless PA (Public Address) is a radio
receiver that allows you to use a base station intercom or mobile
2-way radio to deliver voice messages directly to an attached PA speaker
up to several miles away depending on the installation.
You'll use this solution where hardwired
installation is simply impossible, too expensive, or the installation is
only temporary. The UHF Wireless Public Address receiver and PA speaker are designed for quick setup and
usage to deliver your message to a large campus or property. You can use this device with our other UHF products since it uses the same unlicensed frequencies. When used with
UHF Commercial Intercom or the
UHF Two-Way Radio you can program coding that will restrict
access to the MURS Wireless PA to only those radios that have a proper
code programmed. This ensures that only authorized people have access to
the PA system.
You can use a dedicated communications channel
between the UHF Wireless PA and the radios or intercoms that are
contacting it, which enables you to use your radios or intercoms for
normal communications without broadcasting over the PA system.
To widen the coverage area, you can install up to
two loudspeakers on a single UHF Wireless PA receiver. A single speaker
will cover up to 100 feet. Each speaker comes with a 25 ft. cable.
Cables can be extended by using standard RCA phono cables and couplers.
When 2-way radios are used in the same area as the UHF Wireless Public Address speaker, feedback may result that can render the system
unusable. For those applications the receiver can be programmed to
record the incoming messages and play them back over the speaker when
the talk button is released on the 2-way radio. Recorded messages are
limited to a maximum of 20 seconds.
The UHF Wireless PA receiver requires 110VAC
power. It also comes equipped with an emergency backup battery that can
temporarily power the radio if primary power is interrupted. The
rechargeable battery backup is not intended to operate the radio for an
extended period of time. A heavy duty external +12 VDC battery can also
be used to power the receiver and the receiver can be configured for
powered operation to maximize battery life. A solar panel kit can be
used to power the UHF Wireless PA receiver without the need for a power
supply in locations where AC
power is not available.
An optional magnet-mount external antenna can be installed at a
higher elevation to increase receiving range.
The radio receiver box is not waterproof so it
should be located inside out of the elements. There is an available
weatherproof, fiberglass reinforced polyester enclosure designed to
house the UHF Wireless PA receiver and antenna that can be used for
In heavily populated areas where other UHF radios may be in use,
this unit has the "2-Tone Decode" capability that enables it to only
receive pages from other radios with the "2-Tone Encode" feature. The UHF Commercial Intercom and the UHF Two-Way Radio have this
Once installed, operating the UHF Wireless Public Address
radio receiver requires no human contact. The UHF Wireless PA reduces
installation costs that would otherwise be incurred by using a wired PA system.

UHF in the UHF Product Brochure (requires the free Adobe PDF Reader to view and print).
This Wireless PA system can be programmed to match your existing radios. We can do it for you but we need the frequency and tone codes of your current radios.
