The T24-AR is an active repeater designed to increase or extend range and overall coverage of T24 Wireless Telemetry Acquisition Modules. The repeater allows T24 modules to transmit around obstacles such as building or walls, etc.
The repeater acts as transparent link between the Acquisition modules and the Consumer, e.g Base Station or Handheld Display. The Repeater is powered by either a pair of alkaline ‘D’ Cells or an external power supply (5-18 Volts).
The T24-AR will allow messages to be repeated once which can effectively double the radio range. T24 has a range of up to 200m (650ft) without the use of a repeater. Adding multiple repeaters will not increase the range but can increase overall coverage.

- Q: How many T24 Acquisition Modules (Strain, Current, Voltage) can the T24-AR Active Repeater support?
A: Many devices can operate on the same radio channel depending on the sample rate of the acquisition modules present in the system. Therefore each Active Repeater is capable of supporting up to 200 data packets per second, ie. 10 devices at 20 Hz or 20 devices at 10Hz.
- Q: Can I wall mount the T24-AR?
A: Yes, there are 4 mounting holes on the back of the ABS case.
- Q: Will the T24-AR work with existing units in the field?
A: The T24-AR is compatible with all units in the field except for T24-HS Handheld Displays manufactured prior to June 2011. The T24-AR will not wake and sleep unless the T24-HS has the 2.1 radio version which is now installed into all T24 equipment. Existing radio modules can be upgraded if required. Please contact Sales for more information.
- Q: Would the Active Repeater assist with range if I am using an T24-ANTB or ANTC Whip Antenna?
A: Yes it would provided all your sensors were in the same horizontal plane. If your sensor and receiver are not in the same horizontal plane this can sometimes lead to alignment issues which can often be resolved by using the T24-ANTA as it can radiate in more directions. However the ANT-A does not have as great a range as the ANT-B or C antennas.
- Do I need to align the T24-AR in a particular way to get the signal around corners?
If the T24-ANTA PCB antenna is fitted to the receiver and transmitter then no special directions are needed except that the T24-AR needs to be in direct line of site of both the transmitting T24 module and the receiving T24 module.
