Can I use a KTI 75 cm Antenna(Dish) for a 61.5 wing dish? The LNB is a CM2500 and it says it is compatible with Directv but it doesn't state that it would work with a dish system. I want to improve the signal on 61.5 and currently have a regular size dish on the wing hooked up to a Western Arc dish. I get a "wobble" on transponder 11 with the signal going from 20 in the daytime to 4 or 5 at night. Thanks in advance for your assistance.
