Default J pole question

If by a vertical dipole, you mean a coaxial dipole (though I note people
are now using 'coaxial dipole' to refer to the Double Bazooka), they are
also notoriously bad for feedline decoupling and need further sleeves
(Bazooka Balun) or radials to effectively decouple the feedline.


I assumed when he said a vertical dipole, he meant exactly that. Two 19 inch
wires center fed. It's cheap, versatile, and does a lot better than your
average rubber ducky.

You mount it verticaly for FM, horizontaly for ssb/cw and at an angle for
satellite work.

I suspect you probably haven't read the thread. That was my original
suggestion with the addition of a balun and some detail on feedline
routing.

Some people have more agressive killfiles than others. :-)
