A single stand for testing different horn-type RF antennas is described. Height positioning, as well as 90Œ rotational positioning for vertical/horizontal polarity, is accommodated. Test stand 10 (Fig.1) consists of base plate 11 on which are securely mounted two hollow vertical supports (masts) 12. Each mast 12 contains a movable chain 13 attached to sprockets 14 at the lower and upper ends of masts 12. Both chains are uniformly driven by common shaft 15 attached to gear box 16 mounted on plate 11. Crank 17 provides rotatory motion to gear box 16. Cradle 18 is attached to chains 13 through slots 19. Cradle 18 is provided with a semicircular arc 20 of a fixed diameter. Adapter plate 21 (Fig. 2) serves as a mount for various horn configurations.
