Re: [Elecraft] OT Rotatable Dipole Project

[Elecraft K3]

Thanks for the flowers Ron.  The one compromise I ended up making was not 
getting the aluminum up a full half wave in the air.  Fully half the 
directionality is down a steep hill, so electrically it meets that criteria. 
However the other half is back into the hillside so in that direction not so 
much.  It has still been a very worthwhile pursuit.  This antenna beats my 80m 
@ .5 wave doublet multiband antenna.

I hope this has been helpful.

Actually I should have said 130 feet up!

Beautiful installation Eric. A rotatable dipoles offer an advantage when
they are up high enough (>1/2 wavelength) to provide significant
directivity. 

Unfortunately that is a little difficult for most of us on 80 meters where
the antenna is 130 feet long and needs to be 65 feet up, but some have
actually done it!! 

Perhaps that will be your next project, Hi! 

Have fun!!

Hello List,

Sorry for the OT posting but I want to share my new antenna.  My K3 and this
antenna have been a joy to operate.

Here is the blog on it for anybody who might be interested:

Rotary dipoles work! It's remarkable how directive a dipole can be. And you 
don't have to worry about LP vs. SP propagation.
I also have a full size 20m version. I wrote an article about how I made it 
work on all the bands from 40-10 meters with high power (1.2 kW):
