Cable tv hookup

Back at it again. This time I tried everything again. Neither tv would work with cable. ( no problems with programming a TV). I ran the cable into the sat connection outside and hooked the bedroom tv (189) up to the top connection (sat) . Bam it works. It makes me believe that the digital cable signal will not work with the antenna booster . Basically I had to bypass the booster in order to get the cable to work.

Please Note:  Spectrum converted all of Ocean Lakes’ campsite cable to all digital on March 5, 2018. Our team has worked hard to assist Spectrum’s staff and our guests in this mandatory conversion. It has been a process and we apologize for the inconvenience and frustration it may cause. We continue to work with Spectrum on all issues.

Some Issues We Know About:
• Spectrum advised us that most TVs work. Tube televisions and flatscreen TVs manufactured prior to 2010 do not work.
• The Seiki brand TV rarely works with digital cable (QAM issue).
• Your camper TV must have a QAM tuner.
• The majority of Westinghouse TVs cannot be programmed.
• The splitter inside the camper may not be heavy duty enough and may need to be replaced. Ocean Lakes RV Center has found this rare issue.

Tried everything except the switch.  Does it matter which input the coax is connected to?

I am stumped....very poor to nonexistent antenna reception...and the antenna booster is on.
