TB7100 Base Stations/Repeaters

  1. TB7100 – Overview

    The TB7100 is a compact, cost-effective base station/repeater for use as a line-controlled base, talk through repeater, RF modem, data repeater or with TaitNet TN1100 MPT 1327 trunking system.

    TB7100 base station/repeater features include:

    • 100 channels with CTCSS and DCS sub-audible signaling
    • Covers seven key frequency bands from 66-530MHz
    • Two digit LCD display
    • Four programmable function keys
    • Continuous duty at 25W, 40W (UHF) and 50W (VHF) power output
    • Full duplex operation (when fitted with optional duplexer)
    • Tone on idle and CWID

    Uncompromising base station/repeater design:

    • Entire unit housed in a 1U high rack, including internal power supply
    • Capable of operation at ambient temperatures of up to 140°F (60°C) and lowest -22°F (-30°C)
    • Fans and heatsink designed to give 100 per cent transmit duty cycle
    • Programmable fan operation
    • Integral monitor speaker for audio testing
    • 9-way RS232 serial data port
    • 25-way system interface for connecting external equipment
    • Low standby power consumption (140mA in economy mode, 25W)
    • Rack or wall mounted

    Conveniently compact

    The TB7100 is the only base station/repeater on the market with optional internal power supply and internal duplexer in a slimline 1U format. This makes the TB7100 easy to transport and install; an ideal choice when space for your RF equipment is limited.

    Ideal for single site coverage

    A cost-effective repeater for single site applications such as industrial or campus sites, shopping malls, hotels, small taxi or bus fleets.

    Ease of integration

    Add a T1810 channel controller to create a low cost TN1100 trunked system, ideal for mine or industrial applications, ports and railway stations, building sites, security and maintenance services.

    Data support

    Supports both 12/19.2kbps Tait High Speed  Data (THSD) and 1200/2400 baud FFSK as standard. The TB7100 can be configured as a data repeater or RF modem an is fully compatible with the TM8000 range of mobile radio equipment.
