This antenna is huge and probably way overkill for signals less than 20 miles away. Is it possible this antenna is too large and maybe i should consider a directional antenna? Could it be a multipath issue? Any help would be greatly appreciated.
KOFY has joined another three stations on RF 28 on Mt. San Bruno. The CM4228HD has a wide acceptance angle but KCNZ being a low power station may be a problem. I myself have serious problems receiving RF 28 as do some others.
KRON VC 4 RF 38 is a bit of puzzle, it is a full power station so multipath might be present.
As your antenna likely cannot be moved up / down / left / right / forward / back, the usual suggestion of moving your antenna to eliminate multipath cannot be given. I would guess that your tuners are not being overloaded unless other stations you wish to receive are problems.
As the repack is less than a year away, changing antennas now I do not suggest as the needs after repack may be different.
KGO VC 7 RF 7 moves to VC 7 RF 12.
KRON VC 4 RF 38 moves to VC 4 RF 7.
KCNZ VC 28 RF 29 moves to RF 21 along with KOFY VC 20 RF 28 and the other two stations.
