The OTA TV antenna signal is carried on the same coax cable into the house. How can I uncouple or split the OTA antenna signal inside the house to feed a 2nd TV with only the local antenna signal. This second TV has a short wire as a antenna and weak channel scans, but with the Orby TV local antenna It would have a strong OTA local only TV in my bedroom.
Any suggestions if the on the roof splitter or similar spliter can be added prior to the Orby Box and spin and share the local signal to a second TV.

You could use a conventional satellite TV diplexer to strip out the satellite IF frequencies and DC voltage that is on the cable. There will be insertion loss on the TV as a result of adding a passive device.

The DC voltage and the satellite RF could both potentially damage the TV tuner so you must understand all of what is in play and deal with it thoughtfully.

Continue to use the Orby diplexer outside to combine the terrestrial and satellite signals. Inside, use a 2ghz or better splitter. Run one leg to the Orby STB. Run the other leg to a diplexer and only connect the terrestrial port to the 2nd TV.

The extra splitter will attenuate the terrestrial signal and you may lose weaker off-air channels.

Where our wheels go
The signal loss could probably be minimized by using a splitter at the antenna ahead of the diplexer, and running a separate coax to the bedroom TV.
