I have set up my own dish with motor and it works great. Now am trying to set up a stationary dish for my mother in law but can't seem to get 97W dialed in. I have the dish mounted to two pieces of plywood, anchored down with the cross beams the mounting system came with and the plywood weighed down with eight concrete blocks. The mounting post came with a leveling bead to ensure it was straight up. My idea (question) is about skew or circular rotation of the dish. On my motorized system, the motor's post dealt with getting the correct skew. However, on this stationary dish, there is no facility to adjust the skew. The LBN can be twisted from - 20 to + 20 (markings on the housing for the LBN) which I am guessing could accomplish the skew setting. Is this correct ? For Tucson, Arizona the skew value is - 20.5 I believe. Any input would be appreciated and other things I should check. Thank you.
