[amsat-bb] Re: AO-51 S-Band antenna polarization

[Alan P. Biddle]

John,

It is linear.  You are right that the information exists, but is sometimes
not readily available.  A good place to look is the Weekly Satellite Report
which AMSAT distributes.  For many, but not all satellites, that information
is just below the frequency information.  For AO-51 we find:

Mode and Antenna Polarization:  

V: Linear
U: TX A (usually digital)LHCP
   TX B (usually analog) RHCP
L: Linear
S: Linear

Does anyone know the polarization of the 2.4 GHz transmissions from AO-51. 
Are they circular?  If so which polarity, RHCP or LHCP?  Are they linear? 
If so is there a preferred receiving polarization?  I have examined the 
AMSAT web site and many references on the Internet, but cannot seem to find 
the answer.

Thanks,
