Modified JP-2000, 2x2M5WL+4 dipoles 144MHz

The JP-2000 was heavily reinforced by a boom insert and by using fiberglass tubes for stabilzing the 20m elements and the driven cell.
Boom was extended to a length of 10m and a fifth element for 10m installed.
All elements were fixed by addition of parker screws.
A current balun was wound on 4" pvc tubing with RG-141, coax connector now is DIN 7/16.
It will mount at the 46m level, 8m above the 40m yagi.
Hopefully 15m performance should not be impacted by the 40m beam, otherwise a decoupling stub will be used.

Medion 636Z3
1/300s f/5.8 iso100 full exif
