Honda antenna

Anyone know what the thread dims are on the antenna mast for a 97 odyssey? I measured the thread dia and it is close to 0.192". I assume it is metric. Think it is 5mm?



Sounds right. 10-24 is same dia. 0.190 approx. think Honda mast is inch thread or metric? Gotta dig up a thd gauge at store maybe

Honda only uses metric hardware.
