Need satellite help !

Sorry guys if I have caused confusion. Maybe I can make it a little clearer.

I use Direct TV service and will use one of the receivers out of my house. It is a HD 24.

I only want standard definition in the motorhome. Do not want HD.
I will use only one receiver. I understand that I will only be able to watch the same programming on both TVs when using satellite. Thats fine.

This is a brand new rig so I have never attempted to do one thing as far as for as changing from cable to over/air. Simply switched TVs on one time just to see if they would turn on. Thats it.

Will not be using the roof satellite wiring so am not interested in that.

As I attempted to state above my goal is to be able to pull into a campground and hook up their cable service and also set up the satellite and hook it up also so that I can use either of them or the over/air without going out and connecting and disconnecting. The connection for the cable is already there. I will need to install one for the coax from the Carryout to hook to and the wiring to get it up to the receiver in the entertainment center.

Once I have done that I know I can change back and forth from Cable to over the air by turning th amplifier of and on. Just need to know how i can incorporate the satellite receiver into the mix so that I can switch to it if I desire---again with out connecting and disconnecting coax cables each time. Is it possible or am I dreaming?

Thank you guys very much for your responses and I apologize for the confusion.

I will be using a Direct TV Receiver Model 24.

If this is a HR24 then as I recall the outputs are HDMI, component and composite. It also can be configured for 1 or 2 tuners for the dish.

BTW How is your roof wired for sat considering that different dish mfgs have different wiring requirements and how do you access the wiring? My guess is that if it's wired at all it's for one particular model/brand.

Most rigs are set up with a OTA coax and cable coax with provisions for a switch the output of which is a coax that has a typical TV splitter to both TVs.

The satellite coax is a completely separate coax that runs to the sat receiver. The receiver is connected to the TV via a HDMI cable or other means as noted above - but not a coax. You then switch the TV input between the coax or receiver or DVD or Blue Ray etc.

So run a new coax from the dish to the receiver using any route you choose. I ran a coax from the receiver to the nearest outside locker with a barrel connector for additional coax to the dish.

Then you can start to address how to run the second TV with satellite.

It sounds to me like there is a little confusion here. You do need the extra cable connection for your satellite antenna to the back of the receiver. This will allow the receiver to communicate with the satellite. What satellite service to you subscribe to? Are you going to just use one satellite receiver? Do you expect to get HD satellite reception?

What kind of output from the receiver to the TV does your receiver have - HDMI, coax, or composite cables? How do you currently change your TV input from cable to over the air antenna? All of this info will give us a better idea on how to advise you, especially since you want to connect the rear TV to the satellite receiver as well.

Thanks WyoTraveler--- I appreciate the response. But it would still be necessary to go outside and change from satellite to cable or cable to satellite. I am sure I will need an outside connection for the satellite so that I could connect to the satellite and park cable at the same time and be able to switch from one to the other. Just dont know what I need or how to make the connections inside. I have been told that I need an AB switch to get this done. At what place would I install this switch? Sorry,I am sure not up to speed when it comes to this type of hookup but i figure I can accomplish my goal as stated in original post one way or the other. Thanks again.

As you are probably aware you cannot connect a splitter to the sat input. However, you can connect a diplexer to the sat input. The one input comes from your outside connection. One output goes to sat input. The other output goes to where input cable was vonnected before. A diplexer costs about $1. You may have to get it on the internet.
