1. Assemble mast bolts with hex flange nut loose enough
to allow movement in curved slot without damaging
the painted surface (on each side) (see Fig A). Once
proper alignment is determined, tighten flange nuts.
2. With the provided lag bolts, secure the DBS mount
so that the antenna can be pointed towards the TV
transmitters with clearance from obstructions to allow
for adjusting. Secure at least 2 lag bolts into a stud.
3. Mount the antenna per the 4220HD and 4221HD
instructions on page 7.
4. Tighten all loose hardware.
