3048 Tuned Dipole Antenna • Codan Communications

The 3048 Tuned Dipole is a HF antenna solution designed for base station use.

Codan's 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. The interface box provides connection points for the transceiver antenna control, RF cables and ground connection.

The 3048 has a significantly reduced installed footprint when compared to wire broadband antennas, which is especially suitable for installations where space is restricted.

Key Features

High Performance

125 W RF power capability that can be used for voice (including frequency hopping) and data operation over the full 2.5 to 30 MHz frequency band. The 3048’s radiation pattern is essentially omni-directional with a combination of NVIS (Near Vertical Incidence Skywave) and medium distance propagation performance.

Robust Design

The high strength, lightweight alloy construction is designed to meet MIL-STD-810G for dust ingress, and are waterproof to 1 m as per IP67 standard.

Installation

Codan offers a dedicated 2 section, 6 m aluminum mast, complete with two guy sets, and installation hardware and instructions.

Fast tuning

The tuner has an unlimited tune from memory capacity, and using a state-of-the-art tuning algorithm, new frequencies are tuned in typically less than one second.
