A 30 inch dish is not suitable for reliable reception on this satellite due to the Galaxy 16 satellite located only 2 degrees West. A 30 inch dish is not usually 2 degree beamwidth compliant and the Signal Quality will be affected. Will it work, Yes! Is it reliable, NO!
Central and eastern US within the main beam are not nearly as affected as the West Coast, Canada, Mexico and the Caribbean.
We recently performed several days of signal testing on Galaxy 25 (IA5) for several of our broadcast partners and found that a Winegard DS2076 was not able to provide an adequate signal margin on the horizontal transponders. This has nothing to do with brand of LNBF. Galaxy 16 data services have priority usage over Galaxy 25 DTH services. Vertical transponders are lightly affected, but several Horizontal transponders are hit very heavy.
Would recommend that you purchase a 2 degree compliant dish, many brands ... many models, but shop carefully.
