You can get a "flat coax jumper" from Walmart.com or Amazon.com for about $3.00 that you can close a window or door on to get the signal in the TT. Other than that you will have to figure out how to wire a outside and an inside outlet. Looking at photos it looks like you have an access door to the back of the Frig. Maybe you can find a way to run a coax next to that door or maybe even through it and fish the coax up around the cabinets.
