We have a dish mounted on our RV with a dish network box connected to one TV inside the RV. We also have a built in tv outside. The HDMI cable is now hooked up to the inside TV. Can we use this splitter to connect another HDMI cable to the outside TV and get the satellite signal for both tvs? Thank you

Hello Dave, You can use this to split the HDMI signal coming out of your Dish Box. Then you connect the two HDMI outputs fro this StartTech box to both of your TV's. The only problem is that both TV's will show the same channel since this is splitting the 1 signal coming out from your cable box. If you want the TV's to show different channels independantly, you will have to buy another cable box to my understanding. (Unless Dish makes a dual HDMI output box that supports different channels on each output. I'm not sure.)
