that cable runs up to 350 ft.<br />
in length have little effect on the<br />
over -all performance of the camera.<br />
Provision for Microwave<br />
To facilitate the setup and use of<br />
microwave, a 6 by 15 -ft. area of the<br />
roof has been reinforced with steel<br />
plating. Provision has also been<br />
made for storage of parabolic reflectors.<br />
A 3 -in. pipe has been installed<br />
on the curb or passenger's<br />

side of the truck. This pipe extends<br />
from the floor to about 3 in. above<br />
the roof. There is a smaller pipe<br />
which fits inside the 3 -in. pipe<br />
which can be extended to a maximum<br />
of 5 ft. above the roof. In<br />
locations where it is necessary to<br />
run the camera and power cables<br />
overhead, this pipe can be used as<br />
a convenient anchorage. It may<br />
also be used as a gin pole for lifting<br />
equipment to the roof of the truck.<br />

ation of unequal radiator heights, a<br />

element array efficiency evolves<br />
through a ass combination of the individual<br />
element field strengths.<br />
Hence, theoretically, tower height<br />
(from height versus efficiency<br />
curve) and base impedance may be<br />
assigned and assumed to comprise<br />
an array of equivalent radiators. An<br />
