Hal explained that last post very well
.I cabled my house with new RG6.
Home runs from attic to 5 rooms.
All identical cable.
Living room didn't like something?
Possibly the 1 ghz wall port snap in?
Re cabled living room.
Eventually ran RG11 from street to attic. Then from splitter in attic to living room installed more RG11
Seems still a discrepancy in living room only with older cable box and with my HDTV antenna.
Some TVs get more channels?
2 of the tvs are mounted 15' apart. Identical 2017 Samsung 65" HDTV
Go figure?
