Many times when I see Comet/Diamond/Maldol antennas, the band split shown is 144/430. Why not 144/440, since these are sold here where UHF repeaters are in the 440-450 split. So are these antennas cut for 440-450, or 430-440? Do the ones that come to the USA just use the same packaging as the foreign ones? Any feedback on this?
