Is there any reason at all to have 77 if your locals don't require it or you don't want channels in SD?
Just to add to this, the older LNB for the EA 1000.4 (which includes 77) has an input for a 4th satellite location, while the old LNB for the EA 1000.2 (61.5 and 72.7 only) does not have an input, if I remember correctly. So, the LNB that includes 77 comes in handy if you want some kind of mixed-arc setup, which is the main reason why I have it.The eastern arc hybrid LNB for the H3 is 61.5 and 72.7 only. As a very mobile RV'er though, there have been a number of times when we were on heavily treed campsites where I could "hit" 72.7 and 77 through a small gap, but not 61.5 and 72.7. In those situations, I was glad I had an EA triple sat LNB for our portable 1000.4 dish.
