The J-pole and other end-fed Hertz antennas are prime examples of antenna that can have severe feed line common mode current problems. Can be mounted on the roof, wall, chimney or any other flat surface. About the J-Pole. Place the mast through the mounting base of the J-pole. During what turned out to be an extended tower-raising project (Going from 55 feet to 90 feet), I had my beam down and I needed an antenna that could provide the necessary gain and angle of radiation to talk to my friend Skip down at the South Pole. Figure 3: 2m dipole or J-pole (free-space) vertical radiation. Level up the mounting base and then mark the pilot holes to be drilled with a marking pen. Extends the length of the J pole mount by 4 feet. Easy Up EZ 29-36S Chimney Mount for Antenna Mast 36 ft Stainless Straps EZ 29-36S. Channel Master 3079 Antenna Mast and Pole Mount. If you have a 1:1. A description is then given on how this dual band principal is applied to a fully portable "roll-up" J-pole antenna. The antenna assembly in the picture is two fiberglass pull-rods screwed together with a short feed line and a 2m roll-up J-pole antenna. As for the satellite dish j-pole. Side mounting two J-Poles alongside each other also won’t cause interference with each other.
