The GEOSATpro 4 degree dual LNBF rotating clamp is a unique and exclusive design developed by Satellite AV to be specifically matched with 2 - GEOSATpro SL1 Bullet LNBFs and the GEOSATpro 90cm Satellite Dish or equivilent OEM dish manufactured by Azure Shine. This special bracket allows for precise placement of two LNBFs to optimize reception from two satellites. Perfect for receiving international or religious channels from both satellites AMC 4 and Galaxy 25 with one dish!

Satellites orbit the earth 23,000 miles above the equator. From your install location, this arc of satellites follows a curve starting on the Eastern  horizon following to the highest point directly South and then slopes to the Western horizon. If you are aiming at two satellites directly south of your install location, the two satellites will be at a similar elevation as one another. If the two satellites are located to the East or West of your install location, the two satellites will be at different elevations.  Precise aiming is critical! Even a fraction of a degree movement will result in Signal Quality loss.

The GEOSATpro 4 degree dual LNBF rotating clamp simply aligns the two LNBFs at the correct elevation exactly in the factory designed focus point or sweet spot of the reflector. Our unique design also allows each LNBF's skew (rotation) and fore / aft  alignments to be individually fine tuned to match the exact focal distance, signal convergence point and polarization skew for each satellite. There is no other simple solution available that allows this amount of flexibility, while remaining extremely easy to adjust!

Other distributors offer inferior solutions that use a curved track to roughly place the LNBFs into a mismatched position. Since the LNBFs are raised out of the CAD designed factory placements with this solution, the distributors recommend adjusting the dish to a higher elevation and cross the LNBF feed horn to catch part of the reflected signal from the dish's reflector. These methods result in inefficient performance as the reflector is no longer focusing all of the gathered satellite signals into the two LNBFs and the offset LNBF is no longer aimed into the sweet spot of the reflector. Over 20% of the signals, that normally would be perfectly reflected into a correctly placed LNBF, bounce and fly off to the sides missing the collecting LNBF. These solutions also often require larger reflectors to overcome the loss caused by the mismatch and are certainly not installer or home owner friendly.
