george Posted September 14, 2008 Posted September 14, 2008 And .... the CCU-680 can take an external antenna (e.g. connect to a high gain yaki antenna), which may be useful if the signal is weak somewhere. Not sure if the CCU-550 also acts as a USB flash drive: the CCU-680 gives me 70Mb of free space available for my files. It seems for the ad that the CCU-550 takes a standard SIMM card, whereas the CCU-680 doesn't - so must be pre-configured by CAT with the unique user ID. Flapman, did you managed to test the CCU-680 with an external Yagi antenna?
