TB8100 Base Stations/Repeaters

  1. TB8100 – Overview

    The TB8100 is a high performance base station/repeater designed to cope with the harshest of operational environments. Ideal for any application from a simple conventional repeater to advanced TaitNet Quasi Sync and MPT 1327 trunked systems. Featuring remote monitoring and configuration as well as a powerful local control application it is available in 5, 50 and 100W configurations in a range of popular frequency bands.

    The Toughest Portables in the Industry

    The TP9300 is built for rugged conditions. Your people need a radio that won't fail them, no matter what the environment. Every Tait Portable is proven to meet Military Standards 810C, D, E, F, and G. It is IP67 water proof and can survive countless drops onto concrete.

    We've also run over our radio with a tank, dropped it 100 meters, washed it on heavy duty in a dishwasher, and more. The radio survived, and you can see these tests for yourself at our Tait Tough website.

    TB8100 Base Station/Repeater features include:

    • 255 channels with up to 16 CTCSS and DCS sub-audible tones per channel, making it suitable for use as a community repeater without requiring additional equipment*
    • Covers key frequency bands from 136MHz to 941MHz
    • Tone on idle and CWID
    • Several system interface options including Isolated Audio, Isolated Audio E&M, TaitNet MPT Trunked, TaitNet RS232 and TaitNet Ethernet
    • An Ethernet system interface option enables IP management of user's communications system
    • High specification base station/repeater design
    • Fast key-up time of 2ms
    • Monitor 43 alarm parameters remotely
    • Computer Controlled Interface (CCI) protocol allows external computer equipment to remotely monitor and control a TB8100 base station/repeater
    • Power save option ideal for solar sites with receive power as low as 60mA
    • A built-in spectrum analyzer measures received signal levels across the selected band

    * Advanced Profiles option required

    Complete remote operation

    With many remote monitoring options, the TB8100 is ideal for isolated sites. Users can manage more than 150 parameters remotely with TB8100 Service Kit software.

    Advanced diagnostics

    Monitor your entire network from a central location with the TB8100 alarm reporting option. This means you do not need to manually connect to each base station/repeater to check it, minimizing maintenance time and costs.

    Tough design

    Specified to operate continuously at full power, at up to 15,000ft (4,572m) and as high as 140°F (60°C) in temperature. Large heatsinks mean that no spacing is required between base stations/repeaters.

    Excellent RF specifications

    Outstanding specifications for selectivity, sensitivity and adjacent channel interference make the TB8100 ideal for use in high-noise environments.

    Flexible software

    The advanced profiles option gives you precise control over your channel configuration and access to the most advanced base station/repeater features.

    Transportable option

    Utilizing the same reliable software-based platform that has made the TB9100 industry leaders, the lightweight analog and digital transportable repeaters are packaged in ruggedized cases. The transportable repeater includes a lightning arrester and the pelican case is available in multiple colors to suit the application.
