It is hard to find on which sat the newest and those to come HD channels will be located but I assume (tech also thinks) that 101, 103, & 108 (if memory serves me on that last one) will be where most of the HD channels (mpeg4) I desire will be placed. Q: Rather than use a 5 lnb(too large for my install - see below), couldn't a 3 lnb setup be used to get the HD I want (HD locals LA & NY, 'standard' 'cable type' HD channels (tnt, sifi, disc, etc)) ? Prob: I am trying to use a roof mounted setup on top of my motorhome, so the less the equipment/size the better. I think a 3 lnb/dish setup can be mounted on my winegard roof top but I am most interested in HD and hope (some evidence indicates that the sats around 101 will be used the most) that a 5 lnb does not have to used. Anyone out there with specific info/plans on where and how a 3 lnb/HD-DVR receiver would be able to accomplish this? PS: I now use a dual lnb and can receive 2 sats (dish) with a small 18" oval, so I assume a 3 lnb head and 'wide' dish could/would accomplish the needed 3 sats, assuming the receiver can be persuaded to work with me ) !! Thanks!
