Technical Specifications

Frequently Asked Questions

Q: Which Uniden mobile radios is this extension cable compatible with?

A: The EC660 is compatible with Uniden mobile UHF radios featuring RJ45 microphone connectors including UH7700NB, UH7740NB, UH7750NB, UH7760NB, UH5060, UH8060, UH8070, and UH8080 models. It will NOT work with handheld radios using 2-pin connectors (like UH755, UH620, XTRAK 50) or other mobile radios using different microphone connector types. The RJ45 connector is a larger modular connector used on mobile radio microphones, different from the smaller 2-pin audio jack used on handheld radio accessories. If you're unsure about your radio's microphone connector type, check your radio's user manual or contact us with your radio model number for compatibility verification.

Q: Can I connect multiple EC660 extension cables together for even longer reach?

A: While physically possible to connect multiple EC660 cables in series for additional length, we do not recommend this practice as it may cause signal degradation, audio quality reduction, reduced microphone sensitivity, or PTT transmission issues. Each connection point introduces potential signal loss and impedance changes. The 2-metre EC660 cable is designed as a single extension providing optimal signal quality. If you require microphone positioning beyond 2 metres from your radio, consider relocating the radio unit itself closer to your desired microphone position, or contact us to discuss professional installation solutions for long cable runs which may require signal amplification or different cable specifications.

Q: Will using this extension cable affect my microphone audio quality or radio performance?

A: The EC660 is designed with proper shielding and impedance matching to maintain audio quality and PTT signal integrity when used as a single 2-metre extension. You should experience no noticeable difference in microphone audio quality, transmission clarity, or radio performance compared to connecting the microphone directly to the radio. The cable's shielding prevents interference from vehicle electrical systems, and strain relief protects connection integrity during vehicle vibration. However, ensure connectors are kept clean and dry, the dust cover is used when disconnected, and the cable is routed away from high-voltage ignition wires or other interference sources for optimal performance in your vehicle installation.

Q: What is the dust cover for, and do I need to use it?

A: The integrated dust cover on the female RJ45 connector protects the connector's internal pins and contacts from dirt, dust, moisture, corrosion, and debris when the cable is disconnected from the microphone. You should ALWAYS secure the dust cover over the female connector whenever the microphone is disconnected during storage, maintenance, equipment reconfiguration, or when the cable is not in use. Dirt or moisture in RJ45 connectors can cause intermittent connections, static, signal loss, or complete connection failure. The dust cover is especially important for vehicles operating in dusty environments like construction sites, mining, rural properties, or off-road conditions where exposure to dirt and moisture is common.

Q: How do I install this extension cable in my vehicle?

A: Installation is simple plug-and-play requiring no tools or modifications. First, disconnect your existing microphone from the radio's RJ45 microphone jack. Connect the EC660's male connector (the one without the dust cover) to your radio's microphone jack, ensuring the locking tab clicks into place. Then connect your microphone to the EC660's female connector (the one with the dust cover), again ensuring the locking tab engages. Route the extension cable neatly through your vehicle cabin using cable ties or clips to prevent tangling, avoid sharp edges that could damage the cable jacket, and keep the cable away from high-voltage ignition wires, hot engine components, or moving parts. Position your microphone at your desired location using a microphone clip or holder for convenient access while driving.
