Step by Step Winegard 7000c Antenna Assembly and Tips! 

That was a well done instructional video. The only thing I would suggest changing is that right at the start, you should have paused briefly and pointed to each item and said what it was. This way when you say you are using a part the viewer will hopefully have a good idea what it is before they see you do it. BTW: 1) The transformer is also called a "balun" for "balanced to unbalanced". Coax is unbalanced because it has a small conductor in the middle and big one around it as the shield. 2) With a very directional antenna like the 7000c, the direction you point it needs to be quite accurate. Directional is good because it gives you better signal but the cost is a bit more care.

I like the looks and design of this tv antenna, however, why not simply discard the matching transformer use and now go into the newer tap in antenna connections these other tv antennas use. All you have to do is just make your connector, put lithium greese inside whare the center conductor is at, screw it into the tap in port, heat shrink the connection to the tap in port to seal out moisture, then slip your weather boot over both the heat shrink and tap in connection, and two final parts left, take plumbers goop put it over top the weather boot, again to seal out moisture, then drip loop your cable, again making sure that moisture will drip away from the connection. By doing all this prepreation, your pictures and sound quility will last you forever without any problems whatsoever. Wineguard tv antenna should put in the tap in port which is a much better set up than a matching transformer, I should think. Don't get me wrong, all my tv antennas have matching transformers on them on a 30 ft tower, however times have changed, and newer inventions, improvements have came on the scene.
