Put up a couple of pics of your aerial connection points, fitting a wind up unit when there hasn't been one before will takes a lot of careful planning, I owuld advise to go and have a look at some pop top rigs that have them, routing the cable thru the roof section will be difficult and require good planning, you can only drill once.............if the cable could then be routed into a cupboard where you could fit the booster close enough for the TV to plug into you would be on a winner as running down the inside of the wall would be very hard......you would also need to source some 12v power to run the booster, so lots of thought so being able to check out interiors similar to yours would be a great advantage...................... I would go for a portable on a post set up with a thru the wall socket, units like a Saturn are brilliant, light and not bulky, just plug it in and stick it up in air no need for turning around stuff as its omni directional, cost about the same as a full Winegard set up.
