Hi Billy! Hope your holidays were enjoyable.
I do have the Winegard dome [came w/the PC 2551 when I bought it used] but I haven't hooked it up yet & may not [how many channels do you really need? And I like to see the area; not sit in the RV].
The batwing seems to be working fine at the places we've stayed & so far, I can't justify the added monthly expense of satellite/dish/direct/whatever. Based on other posts on this forum & elsewhere, I did get the Winegard Wingman to improve the batwing reception & it did as advertised - getting that last 25% or so of the UHF signal - only ~$20 on sale at Campers World.
Good luck in your search!
