Two lengths of RG-6..one about 25 ft, the other one about 75 ft. One barrel connector to join them, if necessary. Had to do that once or twice only. I also use the RG-6 for hookup to regular cable TV at those parks which have it.
There is a little right angle "slip on" connector available at Radio Shack for a few $ for a set of two. They screw on into each end connector of the RG-6 cable, and allow you to just slip the connector onto the female connector on the RV connection panel. I really hated screwing and unscrewing the connectors every time we had to install or take down the dish antenna. I also added a short (3 ft) "stub" of RG-6 with a barrel connector to the antenna dish. That is permanently attached. The satellite finder attaches easily between the antenna RG-6 "stub" and the RG-6 from the RV, when I need to use the finder.
As for the tripod, I bought 3 six foot sections of dowel that fit exactly into the square tubing that forms the legs of the "standard" short (2-3 ft) tripod that came with my Direct TV dish. I cut the dowels to the length needed to make the tripod a comfortable height for me to use the satellite finder and adjust the azimuth, etc. A little gray spray paint on the dowels, and you can't tell it from original.
Lastly, I found a neat "leveler" which is a replacement for the vertical tubular part the dish antenna attaches to on top of the tripod. This 8 inch long replacement mount has a large ball joint near the bottom of it, where it mounts on to the tripod, and a level bubble in the top. All you have to do is unscrew the ball joint slightly to allow movement, get the top of the mounting level using the bubble, tighten down the ball joint, and you have a level mount for the antenna. Takes maybe 10 seconds, and you don't have to worry about uneven ground, shims and that sort of thing. I saw a similar setup in the August Trailer Life; Accu-dish leveling device, page 94.
