The 3048 Tuned Dipole is a HF antenna solution designed for base station use in areas of limited space.

When compared to wire broadband antennas, the 3048 has a significantly reduced installed footprint, which is especially suitable for installations where space is restricted. With 125 W RF power handling capability the 3048 can be used for voice (including Frequency Hopping) and data operation over the full 2.5 to 30 MHz frequency band.

The 3048 antenna system comprises a main tuner unit and antenna element assembly mounted on top of a 6 m mast. A control cable and coaxial cable run down from the tuner unit to an interface box mounted at the base of the mast.

Key Features

  • 125 W 125 W RF power handling capability for voice (including Frequency Hopping) and data operation over the full 2.5 to 30 MHz frequency band

  • Small installed footprint with a guy radius of 4m and a self supporting antenna span of less than 10m

  • Fast tuning with 1 sec average due to an unlimited tune from memory capacity

  • Supports ALE and Frequency Hopping modes

  • Omni-directional radiation pattern with a combination of NVIS (Near Vertical Incidence Skywave) and medium distance propagation performance

  • MIL-STD-810G for dust ingress and waterproof to 1m with high strength, lightweight alloy construction capable of withstanding the severe environmental conditions

  • Single mast deployment to suit spaces with a limited size area for deployment
