[AReU] Digital TV and Modern Man

[Bob Haynes]

My motor home has a television antenna to receive signals, and some of the time we stay in travel parks that have cable TV

The coax built into my motor home combines the cable TV and antenna signals, and I have access to only one piece of 75 ohm TV coax which used to run directly into the rear of the motor home's built-in analog TV 

My television digital converter has no bypass.

Please let me know if it is OK to run signals from cable TV through a digital converter.

If it is OK to run cable TV through the digital converter, please disregard the rest of this message.

llllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll

At the present time I have a barrel connector which I can put in between the converter input and converter output coax cables. 
This allows my TV to receive digital, analog, and cable signals.   

I would like something nicer - it's a wife thing.

If I could find a coax switch to toggle between two inputs with one output, that would be all I need.

If there is no such coax switch:

I may have to bypass my digital converter by throwing a coax "A-B" switch which has one input and two outputs.

I could put the coax switch in the cable run ahead of the digital converter, so the switch would send the incoming signal either to the converter input or to the TV

Then I could use a coaxial combiner after the digital converter so that the TV will either see a signal from cable TV or a signal from the digital converter. 
I can turn off the digital converter if it is not to be in service. 

The combiners I have on hand are made with only one input and several outputs.  
What I need is two inputs and one output

(1)        Is it a good idea to reverse the combiner I have and use two outputs for the incoming signals with the combiner input going to my analog TV?

(2)        If the answer to Question 1 is YES, does it matter if my combiner has a bunch of unused outputs? 

(3)        - Or should I buy a combiner with one input and two outputs and try to run it backwards? 

(4)        Or is the only good way to wire in my bypass to use a combiner with two inputs and one output?

(5)        If I need to buy a combiner or double coax switch, does anybody want to tell me where to go?

Thanks in advance for your advice.
If you know of a used combiner I can buy, please let me know.
