A wireless van with whip aerials and some trucks stood parked at the side of the road.

The big whip aerials of the patrol craft shimmered and melted!

When on the move, or during the course of a battle, the low-power radios could still be used from batteries, with vertical whip aerials.

Whip aerials for the VHF set(s) were installed on the front wings of these vehicles, together with their base-mounted Aerial Tuning Units to obtain maximum separation from any HF antenna.

It looked more like a miniature warship with its sharp upthrust bow, rakish black hull and the white-painted bridge structure rising abruptly to the spear-like thrust of the whip aerials either side of the mast, lights, radar, a tangle of high-tech equipment that gave her a very purposeful appearance.
