The new RetroAntenna™ HPA1 amplified hide-away antenna from RetroSound® allows you to get great AM/FM reception without having to use standard fender-mount or window antennas. The HPA1 installs in seconds, using a standard Motorola antenna plug and your radio’s power antenna wire, and can be installed almost anywhere in your vehicle thanks to the supplied 105-inch antenna cable and power lead. Never worry again about a stolen or damaged fender-mount or roof-mount antenna. This antenna uses active magnetic field circuitry for enhanced radio reception.
