Step-by-step guide to remove a damaged AM/FM radio antenna mast and install a replacement on your 2018-2023 Jeep Wrangler JL or Gladiator JT.

Quick Answer

You can replace a broken antenna mast on your 2018-2023 Jeep Wrangler JL or Gladiator JT in about 15 minutes using basic hand tools and a compatible replacement antenna.

Why the factory antenna breaks

The stock whip antenna on the JL Wrangler and Gladiator JT is long and flexible, but it can snap from repeated contact with tree branches, car washes, or garage door frames. A broken mast usually leaves you with no AM/FM reception at all, so replacing it quickly restores radio function.

Choosing a replacement antenna

You can buy a direct OEM-style replacement or a shorter stubby antenna that reduces the risk of future breakage. The replacement we recommend is made from iron and stainless steel, fits both AM and FM bands, and installs without drilling. It is designed specifically for 2018-2023 Wrangler JL and Gladiator JT models.

Step-by-Step Antenna Replacement

  1. Step 1: Remove the old antenna mast: Unscrew the broken mast by turning it counterclockwise at the base. If the mast is snapped flush, use pliers to grip the remaining threaded base. Be careful not to damage the paint on the fender. If the base is seized, apply penetrating oil and wait 5 minutes before using pliers.
  2. Step 2: Clean the antenna base threads: Wipe the exposed threads on the vehicle's antenna base with a clean cloth to remove dirt or debris. This ensures a clean connection for the new antenna.
  3. Step 3: Install the new antenna mast: Screw the new antenna onto the base by hand until it is snug. Do not over-tighten—tighten only until you feel resistance. Over-tightening can strip the threads or damage the new mast. Test the antenna by turning on your radio before tightening fully. If reception is weak, adjust the mast angle slightly.
