The fixed mast barbless antenna mast is designed to withstand most car washes without damage. The mast cannot be adjusted up or down. Straighten the mast by hand if the mast becomes slightly bent. Replace the antenna if the antenna becomes severely bent. Keep the antenna clean for good performance.

The radio receiver mounts in the instrument panel using snap-fit retainers.

The radio receiver and the amplifier are an integral design.

A remote amplifier is used for ULO, UNO and UPO.
