The Radiodetection Tx-5 Multifunction Transmitter has a higher power and induction capability than the Tx-1 model. It also features Fault-Find to detect and pinpoint insulation faults.


The Tx family of signal transmitters has been designed to perfectly complement Radiodetection’s advanced high-precision cable and pipe locators including the RD8100, RD7100, and Marker Locator ranges.

The Tx range is designed to meet the demands of tracing utilities through today’s complex underground infrastructure. 


The transmitter range features locate frequencies compatible with locators across the Radiodetection Precision Locator ranges, and can be easily customized to match your chosen locator using the ‘model’ feature. 


All transmitters feature constant current across their entire bandwidth in all modes (direct connect, clamp or inductive mode), and deliver convenience on-site with an IP65 ingress protection rating, removable accessory tray and a large, high-contrast, backlit LCD screen.

Radiodetection Tx-5 Multifunction Transmitter

  • iLOC Remote Control

    iLOC is an advanced Bluetooth® link between the RD8100 locator and transmitter, which allows you to control the locate signal’s power and frequency from up to 1400’ / 450m away.  Less time walking and more time locating. Only available as an optional extra on Tx-5 and Tx-10 models.


    Fault Find

    Apply a Fault-Find signal with the Tx-5 and Tx-10 transmitter and use an accessory A-frame to detect and pinpoint insulation faults.


    Automatic Impedance Matching

    Transmit your locate signal as far as possible by automatically matching the transmitter impedance to that of your target cable.


    Built for on-site use – IP65

    Shock resistant, ingress protected casing protects against knocks, drops, water and dust.


    Multimeter Function

    Measure output voltage, line voltage, current, impedance and power, and characterize faults on the target line before beginning a survey

    Accessories to optimize the system to your needs.


    90V Maximum Output

    High voltage output makes sure that you can get locatable signal onto even high impedance lines like telephone pairs.



    The transmitter can be used to recommend a general-purpose locate frequency for the intended locate task by measuring the impedance of the target cable or pipe. SideStepAuto helps to improve locate accuracy and extends battery life.


    Lithium Ion Battery Pack Option

    Deliver extended run-time, lighter weight and superior cold-weather performance by comparison to standard alkaline batteries. No need for operators to replace, manage and recycle alkaline battery cells, reducing the associated costs, workload and environmental burden.


    ECO Mode

    Extend alkaline battery life by enabling ECO mode. When a low battery condition is detected the transmitter gradually reduces the power output and provides audio and visual warnings.
