Hello Zoyburg;
Well, I already have a Horizon to Horizon mount on the dish, so would
not need the multiple LNB's. I guess what I need is a LNB with the
standard 1.5" circular throat that would receive the circular
polarized signals and work with a Pansat 2500A. Does anyone make such
an animal?
I also read somewhere that you can use a Universal LNB in place of the
circular polarized one with a corresponding 3 db decrease in signal
strength, have you ever tried this? The dish is 76 Cm dish so
perhaps there would be enough signal to overcome the polarization
loss??
Otherwise, I could try to fabricate a bracket out of wood that would
put the focal point of the Dish LNB at the dish focal point, but that
would not be easy for me to do.
Thanks
