Previous trailer had the Winegard with the wingman and it was quite good. New trailer has a continu-us (brand) CA1500 (model). Installation instructions do not say anything about a red wire but its there. No end is in the roof hole to connect to, just the coax.
I don't have the room for a new winegard crankup style where the coax comes through the roof so I was considering the Kingjack antenna. It may fit the mount that is already there so to just swap it out would be nice. I know the kingjack is another omni directinal but it has good reviews. Who knows if it will be an improvement. You roll the dice, you take your chhances.
