Attention
Retail Customer: This product is
sold as a hobbyist item. It is designed for operation by a more
experienced user. The full manufacturer's warranty applies, but we are
unable to provide installation or technical support on this item unless
it is purchased as part of a complete Glorystar system.
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!
Why is it necessary to
have a rotating bracket to hold the two LNBFs?
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!
What alternative
solutions are available?
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.
