Nissan 240Sx Radio Antennas

Nissan 240Sx Radio antennas

Starting at $43.95, AutoBuffy stocks 1 radio antennas from SKP to fit your Nissan 240Sx. The antenna receives AM/FM broadcast signals and routes them to your head unit — when it corrodes, breaks, or loses its connection, reception drops to static or goes silent entirely, leaving you with no usable radio.

Signs your Nissan 240Sx needs a new radio antenna

  • Constant static or white noise on AM and FM bands even in areas with strong signal coverage
  • Reception cuts in and out while driving, then returns when the vehicle is stationary
  • Only strong local stations come in clearly; distant or weaker stations are completely lost
  • Visible physical damage — bent, snapped, or missing mast, or a corroded antenna base
  • Power antenna motor runs (you can hear it) but the mast does not extend or retract fully
  • Radio works normally through auxiliary, Bluetooth, or USB inputs but FM/AM performance is consistently poor

Which radio antenna should you buy for your Nissan 240Sx?

The right antenna depends on whether your Nissan 240Sx uses a fixed mast, a power (motorized) antenna, or an amplified antenna embedded in the glass. Getting the correct mount style and connector type is more important than brand, since a mismatched base or plug will prevent installation entirely.

Fixed Mast Replacement
Best for
Vehicles with a simple threaded or snap-in mast and no motor
What you get
Affordable, no moving parts, easy DIY swap; basic AM/FM reception with no amplification
Power Antenna Assembly
Best for
Vehicles with a motorized antenna that extends when the radio is on
What you get
Complete motor, mast, and housing unit; restores automatic extend/retract operation and OEM-level reception
Amplified Antenna
Best for
Vehicles with a short stubby mast or poor reception in fringe areas
What you get
Built-in amplifier boosts weak signals; compensates for a shorter mast or shielded mounting location
Glass-Mount / Windshield Antenna
Best for
Vehicles that originally used or can accommodate a adhesive-film antenna
What you get
No exterior mast; eliminates breakage risk; requires a compatible amplifier module and wiring adapter

Replacing a radio antenna on a Nissan 240Sx

Easy15–45 minutesAntenna removal tool or large flat-blade screwdriverPliers or adjustable wrench (with tape to protect finish)Trim panel removal pry tool (for power antenna access)Flashlight or work light

A fixed mast replacement typically takes under 20 minutes — unscrew the old mast counterclockwise by hand or with a wrench, then thread the new one in until snug; no special torque is required. A power antenna assembly involves removing interior trim to access the motor housing, disconnecting the coaxial cable and power connector, and bolting the new unit in place before routing the mast through the fender. Test reception and the extend/retract cycle before reinstalling any trim panels.

Frequently asked questions

How much does it cost to replace radio antennas on a Nissan 240Sx?
Parts start at $43.95 on AutoBuffy. A basic fixed mast is at the lower end of that range, while a complete power antenna assembly costs more. DIY installation is free if you have basic tools; a shop may charge one to two hours of labor on top of the part cost.
Can I drive my Nissan 240Sx without a radio antenna?
Yes, the antenna is not required for vehicle operation. You can drive safely without one. However, AM and FM reception will be severely degraded or completely absent. Bluetooth, satellite radio, and streaming inputs through your head unit will continue to work normally without any antenna present.
Why does my Nissan 240Sx radio get static only on AM, not FM?
AM signals are more sensitive to antenna length, corrosion, and ground connection issues than FM. A loose or corroded antenna base is a common cause. If FM is clear but AM is static-heavy, inspect the antenna base ground and the coaxial cable connection at the back of the head unit first.
How do I know if my Nissan 240Sx has a power antenna or a fixed one?
Turn the radio on and watch the antenna mast on the exterior of the vehicle. If it rises automatically, you have a power antenna with a motor. If the mast stays in place regardless of radio state, it is a fixed mast. You can also check the fuse box for a dedicated antenna fuse.
Will any aftermarket antenna fit my Nissan 240Sx?
Not necessarily. Antennas vary by base thread size, mounting hole diameter, cable length, and connector plug type. Always match the mount style to your vehicle's existing setup. Using the 1992–1994 fitment filter on AutoBuffy's product pages ensures the antenna listed is confirmed compatible with your specific Nissan 240Sx.
How long should a radio antenna last on a Nissan 240Sx?
A fixed mast can last the life of the vehicle if left undamaged, but car washes, low-clearance garages, and vandalism frequently break them sooner. Power antenna motors generally last several years before the internal nylon drive cord or motor wears out. Coastal or high-humidity climates accelerate corrosion on the base and mast.
