Void for vagueness

Dennis Niles

As a matter of contract law, will poor wording bar enforcement of a restrictive covenant?   Recorded in 1994, the restriction referenced in my deed reads:

"5.  No exterior antennas, except normal TV antennas will be allowed. Particularly excluded are satellite dishes &
Ham radio and CB radio antennas."

Clearly, the phrases "normal" and "Ham radio" are ambiguous.  Assuming the underlying concern is aesthetic impact, is it not arbitrary to bar antennas no larger than whatever was understood to be "normal" in 1994 based solely on how the antenna is used?  If so, does this invalidate the restriction and obligate the HOA to reasonably accommodate my communication needs?
