I have an experimental four-element phased array running with 4 short
verticals for the 160M/80M ham bands using the four channels of the
USRP. The beam steering is fully functional, but there are still a
bunch of other issues to be solved to make it a usable system.

They are also called 'smart antennas'.
Basically (very basically) you adjust the gain on different elements
of an antenna which changes the beam properties (gain and width) of
the overall array.

Hi all,
After being on-frequency here for a little while I can see that the
range of experience/expertise is wide. Which is great.
I'm curious if any long-timers have begun to look at software defined
antennas? Or is there any effort at all anywhere in the public domain?
I gues
