INTRODUCTION
Description
The Base Tech II Base Repeaters represents a technological advancement over previous models. The
Base Tech II Base Repeater is comprised of separate modules all housed within one 2RU equipment
cabinet. The receiver, transmitter, and PA unit are each enclosed within their own die-cast housing. Each
one is then mounted directly on the large upper heatsink. A microprocessor-controlled interface module
controls the channel selection, LCD Display, timers, interfaces, and signaling features.
The RF power output is 25 — 110 watts, depending on the model, and rated for continuous duty. The
CTCSS module supports all EIA tones. All tones and different encode and decode tones can be set on a
per channel basis during radio programming.
Attention
The antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent
structures with a separation distance of at least 6 meters from all persons during normal
operation. The peak conducted output power at each antenna terminal must not exceed
250 Watts and the peak radiated output power must not exceed 1000 Watts EIPR. Users
and installers must ensure that FCC requirements for satisfying RF exposure compliance
are met. (See FCC Rules Part 1, Sections 1307 and 1310)
