Overall, this just wasn't worth fitting as a replacement for a whip aerial. The construction is good, fitting straight forward, The soft-plastic seal seems very effective and the amplifier PCB is well protected by additional seals. But the amplifier itself is ineffective. It is clearly operating, connecting the 12V line gives a clearly audible increase in the noise floor, but no additional boost to the signal. Raising both the noise and the signal gives little improvement for FM radio.
