This cable can be custom built with low-loss coaxial LMR-400 cable. Contact us for details.

The DataPro 1840 series cable is a reverse-polarity TNC extension cable that allows you to reposition your antenna or wireless hardware in an optimal location. This assembly features reverse-polarity TNC connectors and is made with shielded coaxial wire for strong connections and noise protection.

This cable is made with RG-58 coaxial wire, having a nominal impedance of 50 Ohms.

Please note that this cable is reverse polarity, meaning that the jack connector has an outer locking ring and the plug connector has the exterior threading. Reverse polarity is commonly found on consumer grade products, while commercial/industrial products may need to use Standard Polarity TNC extension cables.

All of DataPro's antenna cables are proudly built in the USA and are available custom-built in any length or configuration you desire, although we find the maximum effective length for this type of extension to be approximately 75 feet.

For more information on this and other wireless antenna connector types, please consult our RF Wireless Connector Guide.
