A Universal Mounting Clamp Kit is included with the antenna for ease of mounting to the tower leg. The Brackets supplied mount to legs ranging from 1.25 thru 5.00 inches in diameter. The kit generally eliminates the need for any additional brackets, however chain and “J” bolts can be ordered for larger pole installations.
