Japanese DXer, JQ2GYU did basic design of this antenna
This antenna does not need a matching section.
Therefore it is very simple structure.
but A design of this antenna depends on the height
Please contact us for the assistance. you can tell me the height of what
you want. I can design that for you.
I use only the aluminum pipe which I can obtain in Ozamis city
You can buy this pipe specially in the glass shop who install a window
glass. all over philippines.

I received pile up with this antenna from Europe for 3 hours.
That was my experience and very exciting moment.
