OK; just checked your LNB specs - its a linear polarity LNB so no problem there; the L.O. frequency for that puppy is 10,750 MHz - so make sure to set your receiver accordingly. As for LNB rotation; it MUST be possible. The LNB and clamp are designed that way. Just loosen the clamp and rotate the LNB.
now - the trees.... :shock:
if the trees are to the
left of where your DirecTV dish is pointing then they will cause a problem, as T5 is left (east) of
DTV 101. Perhaps you could find a different mounting location for the 30" dish.
