I wouldn't bother. The radio waves don't care. Ask anyone in the end-fed half wave crowd. They know how easy it is to make the coax radiate. What you will need is a common mode choke a quarter wave down the shield.

I would like to put up a vertical sleeved 1/2 wave dipole, using Belden 8279, 75 ohm coax. ?I have been pondering a good way to remove approximately 11 contiguous feet of the outer jacket, of course without nicking the copper shield, but haven¡¯t come to any ideas, that I sense will work well. ?The Wireman and DXE could offer no tools or procedure. ?A sharp blade needs to be run along the length of the coax, while maintaining a precise depth. ?The coax OD is 0.22 inches and the outer jacket wall thickness is 0.074 inches, polyethylene. ?Perhaps a small V-block could be used to stabilize the round coax in position, while holding a knife blade pressed on the outer jacket and pushing down on the cable at the same time to keep the coax in the V, and pulling the coax through; I would not cut completely through the jacket when doing this, but after cutting the entire length, tear the outer jack off. I think I could do this with two hands. ?Any ideas?
Thank you.
