Has anyone attempted to run wiring through the air conditioning duct in a fifth wheel? I am contemplating adding a second antenna lift mount with a yagi antenna on the roof towards the front for a cell booster. This will enable me to rotate the antenna toward the cell tower without climbing on the roof each time I setup. The issue is getting the coax back to the actual booster that I would like to mount at the back of the FW keeping the coax run as short as possible but far enough to prevent any oscillation between the receiving and transmitting antennas. I have one though on how to accomplish this but wanted to check with those with far more experience than me.

Your thoughts and suggestions would be greatly appreciated.

Thanks
