Check out the AMSAT web site, under P3D, and find this link:

	http://www.amsat.org/amsat/sats/phase3d/groundst.html

For the sake of our WWW challenged friends, here is the table in part:

 Mode      Frequency    Antenna 
 U V 
 Uplink    435 MHz     11el. Yagi 12.5 dBdC 1.9m boom 
 Downlink  145 MHz     5el Yagi 9.0 dBdC 2.1m boom 

 U S 
 Uplink    435 MHz     same as UV uplink 
 Downlink  2.4 GHz     28t Helix 1m long or 
                       60cm Dish 
 L U 
 Uplink   1.27 GHz     16t Helix 1.1m or 
                       20el Yagi 1.5m 
 Downlink  435 MHz     same as UV link 
 L S 
 Uplink   1.27 GHz     same as LU uplink 
 Downlink  2.4 GHz     same as US downlink 

If you look around, the AMSAT NA site has VOLUMES of information, and
links to other sites with still more information.  My best advice, if
it's amateur satellite related, start at:
