Thinking about buying a crankup. Got a few questions. Does anyone use a satellite finder with a crankup? Is it easy to find the Sky satellite without one? Don't particularly want to bend down in a cupboard connecting/disconnecting the sat finder due to bad back. Is it possible to get a signal about 60 miles South of Barcelona? What about water leaks? Got a ridged panel roof and have to park on my steeply sloping drive. Told its OK to fix a crankup on a ridged roof but I'm afraid the water will get underneath the fixing plate and leak through the 32mm crankhandle hole. I'm looking for reassurance here as I've been plagued by water leaks in my home and in many of the vehicles I've owned. Thanks.
