DXE sell the 80 mts vertical antenna and it use 0.25’’ OD x 72’’ long 0.035
wall thickness
I have this antenna, blended by the winds I think on the 0.50 or 0.625
sections, nos sure.
Fortunately the tip is ok, and hope DXE will sell this 0.25’’ OD x 72’’ long
0.035 wall thickness in case I have a problem with it
73,
Jorge
