ANTENNA MOUNTING
For optimum results it is necessary to mount the fixed site antenna as high as possible above
the average terrain. It is also required that the antenna be mounted at the top of any metallic
structure (tower or mast) so that there is no metal in the antenna pattern. Do not mount the
antenna near any transmitting antenna. Serious damage can occur if large rf fields are
applied to the antenna. If you are using a radio modem, maintain maximum separation of
the radio modem antenna from the direction finding antenna. Horizontal and vertical
separation is best if possible. See
