i have several, Gwalk900 The1000 is the only one they ever wanted back , the installers always just left the others modems wires and all dishes included , radios and the whole systems , LOL !! you need one to play with , thought about it a few times !!! but food for thought if one uses two coaxes and another uses one coax, i know one is up and the other one for the down-link how is it possible for that same coax dual, cut back to one , function or intergrated into one for up and down-links !!!!
