Two-Pack DIN to ISO Antenna Adapter

This pair of adapters converts a DIN male antenna plug to an ISO female socket, letting you connect a factory coaxial lead to an aftermarket head unit. The 50 Ohm to 150 Ohm impedance translation suits standard vehicle radio installations. Installers and DIY owners can fit both units without tools in minutes.

50 Ohm ISO Female to 150 Ohm DIN Male

The critical specification is the connector pairing: an ISO female jack rated at 50 Ohm on one side and a DIN male plug rated at 150 Ohm on the other. This exact impedance match determines whether the adapter will work with your specific coaxial cable and receiver combination.

Plug-and-Play Installation Preserves Wiring

Each adapter slides between the existing coax lead and the new stereo, so no cutting or splicing of the original harness is required. The tool-free design keeps the vehicle manufacturer’s warranty intact while providing two spare connectors for multiple vehicles or future swaps.

Questions about this item

What does the 50 Ohm to 150 Ohm conversion do for my car radio reception?

The adapter matches a 50 Ohm ISO antenna lead to a 150 Ohm DIN tuner input so the signal transfers without the loss that a straight plug would cause.

Will the ISO female to DIN male connection work with the coaxial cable already in my car?

Yes, the ISO female end accepts the standard coaxial aerial plug found in most vehicles while the DIN male end fits the radio's antenna socket.

How much space does the adapter need behind the head unit?

Each adapter measures about 4 cm long and 1 cm wide so it fits in the tight cavity behind a standard single-DIN or double-DIN stereo.
