[amsat-bb] L Band Uplink Ant

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.
