3/4 front view of GMC truck MT3233 with a Direction Finding cab on the back, on the airfield at RNZAF Station Ohakea.
Associated document describes: "The VHF D/F station at Ohakea located adjacent to the beam approach unit at the eastern end of Ohakea's main runway, photographed from various angles. The beam approach unit can be seen in No. 66 [1986-016.119] near the right hand upper edge of the photograph. The trailer seen in No.s 63, 64 & 65 [1986-016.116, 1986-016.114 & 1986-016.115] contained our AC generator. Although the equipment in the van was battery operated, an auxiliary source of mains power was required to keep the batteries charged. Mains power was laid on from Ohakea station for this installation and the trailer regarded as an emergency source.
The D/F antenna system comprised a pair of vertical phased dipoles backed by another pair of dipoles which could be switched to distort the normal figure-of-eight polar pattern for sense determination. The whole antenna system was rotated from inside the van. The installation was installed primarily for use by fighter aircraft with VHF facilities whose pilots required bearings for homing (QDM's). However, multi-engined aircraft also sometimes utilised the VHF D/F facility with requests for QTEs. The equipment provided a high degree of accuracy, and operators were able to obtain extremely well defined bearings.
So far as is known, the RNZAF had two of these units in operation - one at Ohakea, the other at Ardmore."

Interior view of instruments in the Direction Finding truck, MT3233, at RNZAF Station Ohakea.
Associated document describes: "Interior view of the VHF D/F van looking towards the rear. The cone from the ceiling supports the bottom of the antenna system shaft rotated by the handwheel. Downward pressure on the disc immediately above the handwheel operated the switches at the centre of the "back' dipoles for sense determination. The dual scales with cursor next above the sense disc provided bearing information. The top scale provided direct read out of QTEs, and the bottom scale direct read out of QDMs. The meter above the scales is a signal strength meter which was particularly useful for sense determination. No correction charts were used.
The dual receivers and other auxiliary equipment are seen in racks above the operator's desk on the right. The batteries are contained in the area provided by the raised section of the floor visible to the left of the operator's desk. Immediately above the battery box against the rear wall is the battery switching panel, and above that, the battery charger. A high capacity kerosene heater and blower for the operator's comfort is located in the corner of the van to the left and just out of the photograph."

Interior view of instruments in the Direction Finding truck, MT3233, at RNZAF Station Ohakea.
Associated document describes: " The rack panels above the operator's desk seen in No. 67 [1986-016.120]. To the left of the microphone are the dual turnable VHF receivers, above which are the dual power supply units, and above them a crystal calibrator by which receiver tuning could be checked. The panels on the right were intended for remote transmitter control and line communications with outside units. One of the telephones was a direct line to Ohakea's control tower, the other a line to the Ohakea exchange. The omnidirectional listening watch was actually maintained via a crystal controlled receiver at Ohakea's receiving station, the output of which was piped along lines to the D/F van. Similarly, output from the D/F van's microphone speech amplifier was piped to Ohakea's transmitter station to operate a transmitter there. Standby battery operated transceiver equipment for emergency communications was included in the van, for which the control box can be seen to the lower extreme right of photograph No. 67 [1986-016.120]."
