The AB-621(*)/G is a portable arrangement of equipment used for the
mounting of a variety of directional radio antennas. The mast, with the
antenna mounted, is erected section by section to an elevation of 50 feet
(100 feet when AB-621A/G is used with extension kit MK-2044/G) and then
supported and guyed in place. After the mast and associated antenna are
elevated and secured, they can be rotated to the required direction for
radio transmission.
