Hi Domenico, The HG2414P is a linearly polarized patch. http://www.34t.com/PDF/hg2414p.pdf
The HG2409PC is a circular polarized patch (LH or RH available). http://www.34t.com/PDF/hg2409pc.pdf They are about the same price too. 73, John On Jun 7, 2010, at 3:23 PM, i8cvs wrote: > ----- Original Message ----- > From: "John Belstner" <[email protected]> > To: "Greg D." <[email protected]> > Cc: <[email protected]> > Sent: Monday, June 07, 2010 4:37 PM > Subject: [amsat-bb] Re: CP antenna from 2 WiFi panels > >> Hi Greg, >> >> These panels are patch style antennas and as such you will not be able to > place one behind the other to obtain circular polarization.
