Description Shipping information

The Uniden ATM301 is a 1.8-meter VHF Marine Antenna designed specifically for boating applications. Since you are working on a 1982 Mariner, this would be a suitable choice if you are looking to upgrade or replace your boat's communication gear.

Product Overview: Uniden ATM301

  • Price: ~$99.95 AUD

  • Type: VHF Marine Antenna (1.8m / ~6ft)

  • Design: Ground-independent (does not require a large metal surface to act as a ground plane, making it ideal for fiberglass or aluminum boats).

Key Features

  • Fold-Down Base: It comes with a heavy-duty, fold-down whip mount. This is essential for 1980s-era powerboats (like your Mariner 40hp setup) because it allows you to lower the antenna when trailering, passing under low bridges, or storing the boat in a garage.

  • Construction: Made from UV-stabilized materials to prevent the fiberglass from "blooming" or cracking in harsh sun and saltwater environments.

  • Easy Installation: * Includes 5 meters of low-loss cable.

    • Features an FME plug (which is small enough to thread through narrow holes or grommets in your dash/hull).

    • Includes a PL259 adapter, which is the standard "screw-on" connector used by almost all VHF marine radios (like the Uniden UM355VHF).

Technical Specifications

  • Length: 1.8 Meters (provides a good balance between range and physical clearance).

  • Compatibility: Works with any standard VHF Marine radio.

  • Mounting: Includes the base; typically requires four screws/bolts to secure to the gunwale or deck of the boat.

Why it fits your boat:

If your 1982 Mariner is on a classic runabout or a small fishing boat, a 1.8m antenna is the "standard" height. It provides enough gain for reliable offshore communication while remaining manageable. The fact that it is ground independent means you can mount it anywhere on the boat without worrying about the radio signal being weak due to the hull material.

Note: If you are installing this alongside your motor repairs, ensure the antenna cable is routed away from the engine's ignition wires to prevent "electrical noise" or static on your radio transmissions.
