Is there a filter we should be using to improve the picture? Have any of you had a similar experience and if so how did you solve the problem? Thanks in advance for any suggestions.
I'm uncertain as to what sort of coaxial cable is in your TT now, or what Airstream has been using in recent years. page 131 of the 2004 Classic Owners Manual Airstream, Inc :: Travel Trailer Manuals
has a drawing that seems to indicate a 1999 upgrade from RG-59 to RG-8/U cable, but the drawing notes vs. the drawing itself is unclear to me. RG-59 cabling, for your desired use, is generally inadequate.
in residential and commercial applications for satellite, cabletv, FIOS, etc. sources, we spec RG-8/U quad shield wiring throughout, including from tuner boxes to the sets (presuming that the box & TV don't have HDMI connections.)
if there are any splitters, amplifiers or other devices in your wiring, they need to be "rated" for satellite signal, or at least 2 Ghz bandwith. a 1 Ghz device won't adequately pass a satellite signal properly, so you might want to check the plates on those devices. that same drawing also refers to a "booster" which may be tucked away somewhere.
otherwise, if there are any additional unused TV "outlets", they need to have an "F-Series Terminator" screwed into it, like these IDEAL INDUSTRIES, INC. - F-Conn.Terminators, 10/card
think of it like capping an open ended water hose.
hope that this is helpful....
