amateur radio satellite deduction

There are amateur radio satellites:

Their location is given many places:

A group of hams builds satellites and is getting the next one launched by SpaceX:

Hams make their own computer controlled antennas, very directional, point them where the satellite is published as being, and talk to someone far away who is also pointing his highly directional antenna at the satellite. There are pages and pages of web sites and youtube videos of hams showing how to build a satellite radio and showing them talking to satellites. All this only works geometrically if there are transponders at 250 mi altitude traveling the orbital path. This all makes perfect sense on RE.

How does this work on FE?
