The work deals with the design and construction of a portable antenna for military operational vehicle. It involved the construction of the prototype of the designed dish, though the prototype was without a feed, as well as using mathematical models to obtain the parameters of the dish antenna by varying the diameter and depth of the dish as well as the frequency of operation of the antenna. It was observed from the result that as the frequency of the VSAT increases, the gain of the antenna also increases while the beam width, diameter and depth of the dish decrease. It was concluded that increase in frequency of operation of a dish antenna results in increase in gain and decrease in beam width, diameter and depth.
