<div dir="ltr">The mast is on a fence, and the cable is a continuous length from the pre-amp all the way to the surge protector next to the TV. In other words I prefer not to break the cable at the exterior/interior point.<br>

At the house end of the cable is the most convenient. You are just<br>
ensuring that the shield is held at ground potential. Before the<br>
pre-amp would usually be pretty far from ground (and literally the<br>
ground).<br>
