Installing A Floor In An Aluminum What Is The Common Way To Wire An On Roof Tripod Antenna Into The House?

What is the common way to wire an on roof tripod antenna into the house? - installing a floor in an aluminum

I have an old rooftop antenna tripod) (analog TV, installed by a roofer when he broke me 10 years ago. In the last 2 years has grown very poor reception on some stations. So I went on the roof and the antenna in the right direction, but noted that no wiring is required (wire mold is peeled and the rest is broken pipe), and realized that the roofer cables connected in unusual ways .. . through the bottom of an aluminum-vent that looks like a kind of mushroom flat metal square. Unfortunately, to replace him at this point, we break the seal and there is no way (no idea and no tar) to seal properly again. I was told is not the normal way to run the cable into the house. What is the normal way? It is a two-story house, connected with external antenna to1st the ground and 2 Bedrooms on the ground. The other room has only rabbit ears and the reception is very bad! Thank you for your help.
