What do most folks use for a L Band uplink antenna?

Wayne W9AE replies:

The Teksharp 4-foot mesh dish kit was popular in the final months of 
AO-40 operation.  Most people used it with a dual band patch feed, so 
one dish is used for L-band uplink AND S-band downlink.  The TranSystem 
AIDC downconverter from K5GNA worked well in this setup because it 
doesn't require extra filtering to reject strong L-band TX signals.  The 
4-foot mesh dish has less wind load than a solid 3-foot dish and more 
gain than the biggest yagi or loop antenna.
