Barrett Supplies HF Equipment for Surveillance Boats in Chile
Monday, March 19, 2018 | Comments

Barrett Communications supplied high-frequency (HF) radio communications equipment for surveillance boats that operate in the remote and environmentally challenging Aysen región in the south of Chile.

The Aysen región in Chile is not only remote but also has lake systems, islands, mountains, rivers and extreme climate conditions. The Barrett authorized dealer in this region, Skytel Telecommunicaciones, is involved in many organizations that are critical to the community. These organizations include health care services, the aerodromes, the agricultural and livestock service, the national emergencies bureau and the uniformed police.

The HF stations are used in offices, service vehicles, ambulances, and surveillance and border patrol boats.

“We have designed and installed a complete HF mobile station on the surveillance boats, and the crew can maintain communications over the HF network throughout Chile,” said José San Martín from Skytel Telecommunicaciones. “Everything was installed without interfering with the factory-installed equipment, and the project was previously approved by the boat's manufacturer to keep the factory warranty.”

The mobile installation kit for the HF transceiver was installed inside the port console, and the unit’s detachable front panel along with the external speaker and push to talk (PTT) were installed onto the port console, as requested by the client. From the transceiver, a control cable was installed and channeled below the cabin's deck to a crew member seat, where a tuner was installed in available space under the seat. From there a cable went through one of the cabin walls to reach the HF antenna installed on the port side of the boat using a specially designed mast and a fixing plate.

The HF mobile station was tested under real-life conditions and was able to establish good-quality communications to the nearest port, the closest town, other stations within the same region, and the main station 1,700-kilometers away.
