In high wind areas keep the mast pipe as close (low) to the last mast support as possible. Keeping the mast pipe to within a few feet of the top of the mount is best especially if a larger antenna is in use. If you will be installing a rotor keep the mast pipe between the rotor and the antenna as short as possible. This will reduce the stress on the pivoting portion of he rotor. If a rotor will not be used mount the antenna within 5 feet of the mount for larger directional antennas and up to 10 feet when installing smaller antennas such as the EZ - HD , MS 2000, miniMAX etc.
