A mast is round and solid.
A tower may be round and solid, or latticed.
An antenna support structure is BOTH, which is why many bylaws and state
laws use the expression "antenna support structure." 47 CFR Section
97.15(b), the codification of PRB-1, calls them "Station antenna
structures." Quote:
. . . a station antenna structure may be erected at heights and
dimensions sufficient to accommodate amateur service communications.
(State and local regulation of a station antenna structure must not
preclude amateur service communications. . . .
DA 99-2569 and DA 00-2468 refer to "antennas and support structures," as
well as "amateur radio antenna structure[s]."
I suggest that it is not a "big red mark" to call these things antenna
support structures. Instead, it might raise a red flag if they were
called masts.
