Vehicle FM/AM signal booster

This antenna amplifier strengthens FM and AM radio reception for cars, RVs, Harley motorcycles, boats and golf carts. It connects directly to a 12V supply and uses a copper signal line to resist interference. The plug-and-play design requires no specialised tools or wiring changes. Drivers who want clearer audio from distant stations will benefit from the added gain.

12V operation and noise filtering

The unit draws 180mA from the vehicle's 12V system and provides 25-30dB of peak signal gain. Built-in noise filtering reduces background static so music and speech come through more clearly. Because it installs inline with the existing antenna, there is no extra load on the vehicle's electrical system beyond the stated current draw.

Inline fit with adhesive mount

The amplifier sits between the antenna and the radio, so it needs a 12V feed and the factory antenna cable. A 3M adhesive pad is included for securing the module to a flat surface inside the vehicle. It does not replace the antenna itself and will not improve reception if the antenna or cabling is damaged.

Questions about this item

How do I wire the 12 V power lead and where do people usually make a mistake?

Connect the red wire to a switched 12 V source and the black wire to ground; the common error is tapping constant battery power so the amplifier stays on and drains the battery.

What part of the antenna amplifier will need attention or replacement over time?

The adhesive pad that secures the module can lose grip from heat cycles; replace it with fresh 3M tape if the unit starts to shift.

At what point does the 25-30 dB gain stop improving reception during a long drive?

Once the incoming signal is already strong the extra gain adds noise instead of clarity, so the limiter is the amplifier’s own noise floor rather than distance.
