Harmony Audio HA-44PW22 Replacement Power Antenna Mast - Supra 87-88

In this review the Harmony Audio HA-44PW22 package is evaluated for owners restoring or maintaining a Toyota Supra from 1987-1988. The bottom line: this kit is aimed at shoppers who need a direct-fit, factory-style powered antenna replacement and a short extension cable so the radio antenna system works exactly like the original. The reviewer found the unit to be straightforward to install for anyone comfortable with basic vehicle wiring and trim work, and the inclusion of multiple mounting bases makes it flexible for restoring correct geometry and appearance.

Key Features

• Direct fit for Toyota Supra 1987-1988: Designed to replace the factory powered antenna mast and connect to the original radio for an OEM-style installation.
• Fully automatic 12V operation: The motorized mast raises and lowers automatically when the radio is powered, matching the behavior of the original unit.
• Six mounting base options: Multiple base angles and a flush option allow the mast to be mounted to match the vehicle body angle and maintain correct antenna tilt.
• Stainless steel 31 in mast: A five-section stainless mast provides corrosion resistance and a length equivalent to factory specifications for good reception.
• Includes 12 in extension cable: The HA-ANTEXT12 extension gives additional reach where the factory coax or connector needs extension or replacement.
• Factory grade materials: The overall finish and components are intended to match OEM quality for a period-correct restoration.

Who It's For

This package is best for Toyota Supra 1987-1988 owners performing a radio or antenna restoration who want a powered mast that behaves like the original. It is also useful for technicians replacing a failed original power antenna motor where the original connector and mounting footprint remain usable.

Those who should look elsewhere include owners of other vehicle models or years, or anyone who needs a decorative, non-powered, or custom-length antenna mast; this kit is purpose-built for the Supra and expects a 12V powered antenna circuit and typical under-fender clearance.
