Overview
The roof rack has been designed by Barrett Communications Pty. Ltd. as an integral part of the
antenna system. The ground plane is a heavy-duty aluminium mesh floor, welded to an enclosing
frame which maximises current in the radiating loop. The 2018 Barrett Mobile Magnetic Loop Antenna
shields and isolates vehicle ignition noise and interference from adjacent power lines providing greater
communication clarity.
The 2018 Barrett Mobile Magnetic Loop Antenna can be fitted to almost any surface. The roof rack
comes in a range of mounting bracket options. Solutions are available that will allow clamping to the
roofs of 4WD’s, sedans, buses, trucks and prime movers. It is designed to minimise head wind noise
with an angled deflector mounted on the front of the unit.
A simplified diagram of the parts that make up the 2018 Mobile magnetic loop HF antenna is shown
below.
