Joby, (or anybody else in the know) I understand what you’re saying about the 4 times faster update not being able to process through the Interlink and I understand the wiring diagram, but if you used a splitter (y-cable) from a single antenna into two extension cables and plugged the extension cables into a Y cable (with the other end of the “Y” coming from the Interlink) and then plug into their respective units, could you not have both the front and the back units work “4 times faster” and still only use one antenna? The reason I ask is I would think accuracy would be better with one antenna and I want to upgrade to the new 50 channel antenna and I’d rather only buy one.
