If you can rotate that one, I'm impressed.

Actually, I can rotate that 130 ft dipole. I live on a
triangular shaped lot so I can rotate it about 60 degrees
from either end. Presently, I have it oriented so the cloverleaf
lobes point toward the world's land masses on the higher bands.

Ahhh, enigmatic as usual! ;-) But let me guess:

Do you have alternate attachment points for one or both end(s)
of the antenna, and transfer said end(s) manually from one
attachment to the other?

If so, I would probably call the process "limited re-orientation"
or some such, vs. "rotation." But it's your antenna, so you get to
call it whatever you'd like.

And I guess there's no joy on modelling the average gain of
said antenna over azimuth. Oh well, it was a nice thought. 8-(

Good DX es 73, Ed

I have three poles arranged roughly in a triangle. My antenna has
quick disconnects on each end. It takes maybe three minutes to
rotate the antenna by 60 degrees.

And I guess there's no joy on modelling the average gain of
said antenna over azimuth. Oh well, it was a nice thought. 8-(

I offered to publish the azimuthal radiation pattern so you can
be the one to waste your time adding up 360 gains.

Cecil,

If you wish you can send me the *.ez file and I'll run it with
MultiNec using the EZNEC engine. As MultiNec is an Excel worksheet it
is very easy to set up an unused cell to give the average gain of a
polar plot.

Or if you wish you can do it youself. MultiNec can be downloaded at:

Hi Danny,
I'm at work and the file is at home, but it is just a 130 ft.
dipole, 40 ft. high, used on 10.125 MHz over average ground.

The wire in EZNEC looks like: 0, 0, 40 130, 0, 40 #14 131

Based on the above, the average azimuth gain @ 34º EL is 1.822 dBi

Thanks, that beats the average azimuthal gain for a
ground-mounted 1/4WL monopole.

Hi Danny -

Thank you very much for your contribution here!
Any chance you could run another 360 azimuth cut
at 26 degrees elevation?

TNX es 73, Ed
