direct tv dish/cable

Is the park cable connection compatable with a sat dish?

No. Cable and sat are completly different systems. Your cable connectin on the coach goes to a splitter and then to the cable input on each TV.
The sat connection must go directly to a sat receiver. The receiver then connects to the TVs in one of three methods depending on how new everything is.

as stated above - Usually no.

There are several ways to do it. Winegard recommends the diagram below.

Making the connections the way Winegard recommends does not require adding any coax connectors to the wallplate.

Note that this assumes your front TV is connected to the coax connector on the front of the wall plate. If yours isn't, there should be a splitter in the line labeled "To second TV" that will send the signal to both the front and rear TVs (if you have two TVs).

What Winegard calls a "power supply" below is the wall plate with the antenna booster switch and LED showing when the amplifier is on.

If you still want to be able to use the external cable in for both cable TV and the external dish just add an A/B switch to switch the incoming coax from the sat receiver "sat input" to the sat receiver "TV input".

If your receiver doesn't have a coax output (and many new ones don't) and you still want to use the batwing antenna you will need to use an A/B switch to switch the signal between the receiver and the antenna out connection on the wall plate.

One thing not shown in the diagram is using the RCA type connections or the better quality "component" type output or the HDMI (best) output between the sat receiver and the TV.
That will yield a much better picture with no interference from any local channels. You have to select a "video in" with your TV menu instead of using channel 3 (for example).
Some newer satellite receivers don't have a coax output so you may have to use HDMI or component connections.

If you have a video distribution box that will have to be taken into account.

Not 100% accurate. You can split the signal from the dish to use two receivers. Cable tv uses rg59 cabling and satellite uses rg6. IIRC satellite coax (RG6) will work for cable tv but not the other way around.

If you are asking if you can use the cable connector on the outside of your RV to hook up a portable satellite dish, the answer is "maybe." It depends on what type of coax was used, how it is hooked up inside the RV, what kind of dish you want to use, and what satellite receiver you have.

A couple of things:
RG59 coax will work fine for most installations but has higher loss than RG6 and RG6 is a better choice. I have used 75 feet of RG59 form the dish to the receiver and the signal was still over 80% as measured by the sat receiver.

Any splitter used between the dish and receiver must have one port that passes DC voltage to the LNB on the dish. It needs the voltage for power and for switching transponders. Half of the transponders transmit with one polarization - clockwise - the other half counter-clockwise. The receiver sends a 13 volt dc or a 18 volt dc signal to the LNB on the dish to select which polarity is selected and thus which set of transponders is selected.
Even if DC pass splitters are used and two receivers are connected, the signaling voltages would conflict and at best would still allow only half of the transponders to be selected, meaning you would only get half of the available channels - if it worked at all.

Most dishes had two LNBs and if you ran two separate coax cables you could connect two receivers but no splitters would be needed.

We use the "Cable TV" connection in our storage bay for a portable Direct TV dish. Inside I disconnected it from the switcher "cable TV" input and connected it to the satellite receiver. We never use CG cable.

Your cable inlet may go to your TV selection distribution box.

If it does, all you have to do is remove the cable that comes from the outside cable inlet and connect that cable to your satellite receiver IN.
