Hi all,

I am looking for a vendor that supplies dipole antennas @2.4Ghz such
that the feed extends from the phase center of the antenna.

The reason for this criteria is that I am hoping to measure the
wireless link with the antenna element at the receiver at both
horizontal and vertical polarizations. It is important for my
measurement that I am able to keep the phase center constant for both
polarization configurations.

The easiest way I can think to do this is to have a centerfed dipole,
fix the feed in position, and then rotate the element around the feed
for the orthogonal element. All the dipoles at hypertech where I
usually purchase from are end fed.

Any suggestions on a vendor or perhaps an alternative approach for
taking such a measurement would be greatly appreciated. Thanks,

Kev
