Yes it will fit like you said you might need to put some kind of struts on it just because the older masts where not made for that big dish but it should be fine with out any support
MikeD-C05 said:My eastern arc dish that I installed myself is on a fence pole and no struts. It has worked fine for over 3 years ,except for when I removed it during Hurricane Ike. I didn't want to have to replace it like I did my dish 500 back in 05 during Hurricane Rita. That hurricane crushed my dish 500 into a C, but it was still on the fence pole. I get signals in the 60s on the 72.7 sat /45- 55 on 77 sat/50 - 70 on 61.5 sat.
I find it hard to believe you would have hurricane fade, but if you thought it was your best interest to take it down
