FYI, I use the X2 and a Wally in my fifth wheel and I keep high quality 25' and 75' RG-6 quad-shield coax on the rig for connecting the X2 to my Wally. I have actually had to use both with a coupler for a 100' total length without any issues. You milage may vary. I will say I have to connect directly to my Wally. Even though the coax system in my rig is supposed to support a satellite connection it will not work with my setup. Also, I find the Eastern Arc preferable and easier to attain in most circumstances. You also have one less satellite to have to wait on the unit to switch to. Also, the 129 satellite on the Western Arc gets pretty low in the sky here in the mid-west and more often than not ends up blocked by treetops. Good luck.
