Blast7,
Several options exist, but I propose (in no particular order):
1) FODZ 1881 3A manual assembly
2) F3AZ 18A886 A antenna mast w/toothed belt
3) F3AZ 18A886 A antenna mast w/toothed belt, adding toggle switch control
for raising/lowering (override head unit "on")
If you go with OE, I'd highly recommend motor disassembly to remove the
broken pieces of toothed belt. Otherwise, you may end up like me: quick
install of new mast lasted two months, and yielded one unhappy pappy.
My Ford Master Mechanic brother-in-law is more forgiving of these parts than I, but
they appear to be a cheap, shoddy excuse of a power antenna (Hondas are no
different). How many SHO's have you seen with a nonfunctional antenna?
