You can donit but at these frequencies you’re not going to see much improvement and depending on your splices could make it worse.
Well, that last is what I was thinking, and am hoping to find guidance on, essentially, “proper splicing”.
I’d have to splice to get the antenna up in the attic regardless, so, eliminating the thin cable might not be much of a bonus, but, IF splicing didn’t cause trouble, it seems like I might as well use lower loss cable...
Any guesses on the losses in .11” dia. 75 ohm coax @ DTV UHF band frequencies?
