i have not had a problem yet. only 4 out of about 40 installs i have used 2.25. no callbacks on them though. atually i came across a job the other day...worst hopper install i have ever seen. one extremely old 1800mhz and one 3 ghz which had been completely cut in half by a lawnmower or something. both cables running from a dish mounted on a wobbly fencepost bare aboiveground across the yard about 100 feet to the node. running hopper and 3 joeys and was working fine. as i said, one of the cables wasnt even connected. the call was to move a joey. of course i reinstalled the whole damn thing, but still, it had been working fine since june.
