Switching atenas

[TJM44]

I have the aplified winegard 3,I was told the amplified winegard 4 was better and would receive more channels.Is this true?If true,can I replace the 3 with the 4?Do they bolt up the same way?I was also planning to add the wingman to the 4 as well,thanks

If you are referring to the Sensar RV antenna then the only advantage to the 4 is that is has a built in Wingman. If you have the Sensar 3 and you add the Wingman attachment you will have the exact same thing that you would have if you paid the extra for a 4.
