Aftermarket head unit - signal booster query

Post by steviemac »

Afternoon chaps,

I've replaced my Gamma unit with a double din Android but the radio reception wasn't the best. Given that the original Gamma fed 12v up the centre coax to boost the antenna, I've fitted a Halfrauds signal booster and taken the feed from the correct wire from the rear of the unit, but with no real improvement. I've pulled the unit and established with my meter that I'm getting 12v to the booster, and have then pulled the VW antenna cable out and inserted the meter terminal into the centre coax on the booster - nothing. I'd have thought I should be seeing 12v here?

See pic below of generic booster similar to mine, red arrow is where I've inserted the terminal

Any thoughts???
