FM radio amplifier?

[ToddD]

Trying to boost the fm signal going to my Furrion head unit. Has a typical car radio antenna input, and I have both 12v and 110v power available nearby.

Suggestions?

Sorry, should have been clearer. Already an antenna hooked up to it, mounted on side of rig. Just looking to boost some favorite stations at places we frequent.

So there's a hookup on the radio with nothing on it ? :h

Should have the standard antenna on the roof. If so, there's not much to be approved on. The tuner in the radio itself could be the issue.
