Datron Cruise TV STS Antenna/Radome

IIRC, when you remove the dome you will find the antenna is simply screwed to the roof from the inside. You can simply cut any cabling that exists if it was factory installed as this cabling would be wire tied into the rest of the wiring and cannot be used as a pull wire. If it was installed after market it should be pretty obvious and you will be able to see the entry location from the roof and from inside. If that's the case you can run the Winegard wiring through the same hole.
