We had our Southwind out for a shakedown cruise. One of the items I looked at specifically was how the TV, Cable, and Satellite systems performed when hooked up.
I had sorted out all the coax connections and where they went to and was able to test the two different configurations (Satellite or Cable) that we would regularly use.
We have a standard Winegard TV antenna with amplifier. I had replaced the coax on the roof as it was getting brittle. One item I noted when making the repair was that the amplifier was connected differently than my previous motorhomes. On my past motorhomes, the amplifier had an ON-OFF button. This did two things; 1) It supplied 12 volts to the antenna amplifier that’s built into the antenna, and 2) it switched the output of the amplifier between the antenna and the park cable.
On my Southwind, this button only supplies power to the antenna, there is no switching of the “Antenna / Park cable”
I made a diagram of how my Southwind is wired. The big difference is how I connect my Satellite antenna to my receiver.
On my old Mirada, I added a dedicated coax and external connector that was specifically for the Satellite antenna. (I’m thinking of doing this for the Southwind).
On the Southwind, there’s a cable that runs from the wet bay to the TV cabinet that can be used for either Cable TV or the Satellite antenna. This dual use cable isn’t a big deal as I don’t envision ever connecting both the Satellite and Cable at the same time.
The Satellite receiver is two receivers built into one. It also has a built in modulator and I can select what channels for the receivers to transmit on, currently have Rx1 on Ch 54 and Rx2 on ch 64. Rx1 also connects to the front TV via an HDMI cable.
The Receivers Coax output connects to a Combiner where the ch54 and ch64 can combine with the regular rooftop antenna signals
