Hello All: I am new to this forum and I am not a technical person. My question is as follows: I have a Winegard DIRECTV SWM Slimline HD TRAV'LER Automatic Multi-Satellite TV Antenna(SK-SWM3) on the roof of my coach. There is one wire coming down into my coach. I have 2 HR 24’s - one in the front & one in the back. The one in the back is connected by a coax coming from a splitter in the front. Can I replace the 2 HR 24’s with 2 HR 44’s without changing any equipment or wiring or can I only swap out the one in the front? Thanks!
