Converting a 2M J pole to muli-band 2M/70cm — by Denys VK3ZYZ
My old 40 year old 2M J-Pole was kicking about unused, so here is the
mod I did to it.
It is not as good as it was on 2M but now I have 1.5:1 on 2M and 1.1:1 on 70CM. That is good enough. It took me a lot longer to mount it and
run the cable than to do the mod. I just added a 70CM radiator. It is 171mm long. This was just moved in and out a bit and the VSWR tested. No doubt it could be better, but now I have a dual band vertical on the roof of the house
I wonder how many others have an old 2M J-Pole that would be ready for a
simple dual band mod??
VK3ZYZ Arduino VFO Version 1.
This programmable oscillator can replace crystals and convert a crystal based radio to a synthesized radio for less than the cost of a single crystal.
Denys is making the printed circuit board for this project available free of charge to club members.
