Antenna extension cable

This 4 ft extension cable connects a radio unit to an antenna on land vehicles or marine vessels. It includes impedance-matching capacitors to maintain signal quality over the added length. The Metra 44-EC48 is designed as a direct plug-in adapter for antenna wiring. It provides the extra reach needed when the factory cable falls short.

Installers needing extra antenna reach

Technicians who must route an antenna cable around obstacles or to a distant mount will find the four-foot length useful. Builders working on vehicles where the radio and antenna are already close together do not need this part. It is not a signal booster and will not improve reception on its own. Buyers who require a different connector type should look elsewhere.

Four-foot length with impedance-matching capacitors

The 4 ft cable and built-in capacitors are the specification that decides fit. The length determines whether the cable spans the required distance in the vehicle or vessel. The capacitors preserve the correct impedance so the radio sees a proper antenna load. Verify both the needed reach and the connector style before purchase.

Questions about this item

Does the 4 ft Metra 44-EC48 extension cable generate any heat or noise when the radio runs all day?

The 44-EC48 is a passive antenna extension cable with impedance-matching capacitors, so it produces no heat or noise during continuous operation.

What existing radio and antenna connectors must I already have for the 44-EC48 to work?

You need a radio and an antenna that both accept the standard connector type used by this 4 ft Metra extension cable.

Will the 44-EC48 cable work with an older factory antenna on a classic vehicle?

Yes, the 4 ft extension cable with impedance-matching capacitors is designed to connect a radio to an antenna on both land vehicles and marine vessels, including older setups.
