7.2.3 CM230, CM230XL adjustable angle mounting kits
The CM230 and CM230XL adjustable angle mounting kits (

allows the component being mounted to be aimed at a specific location. The CM230 is used
when mounting the component close to the mast or tower while the CM230XL extends the
component away from the mast or tower.
