cambria county on AVS extended the rear elements on his RCA ANT751 to be able to receive WQED from Pittsburgh. It moved from 13 to 4.

I made the rear elements about 48" each side. I used elements from old antenna's. Just used flat screwdriver and pliers to open seam where the slit is. Slid onto existing element and ran foil tape around it. Before I did this, Wqed was not decoding on the Zenith box. It was very close to opening. That is when I got the idea to extend back elements for rf-4 aka Wqed. I was suprised how strong it was after I did this. On another note, I ordered stellar labs version of the Rca-751 and the fringe yagi 30-2476. Wtov 9-Steubenville not quite strong enough to decode with Rca-751 here. (90 mile signal). I think the 30-2476 will get the job done. Hopefully, I can shoot for Wtrf-7 Wheeling, also. The cw-rf 11 is real easy to get here for some reason. Fox 8 comes in very strong with the rca-751.

Those elements are a little too long for channel 6; should be more like 33 or 34 inches on each side.

This is what the Winegard HD7000R looks like with the VHF-Low extensions added:
