Inspired by a YouTube video in which an antenna booster for an Inspire was presented, I rummaged in my crafting corner and built it myself in 15 minutes using simple means. You need 2 coffee lids, 2 pieces of copper sheet 0.2 - 0.5 mm, hot glue, a small drill and a file. The photos show the simple and quick assembly. It's definitely not as good as an amp measured in a lab, but it's more stable and keeps going for me now. The photo gallery shows the structure.
Of course I can't, don't want to and won't give any guarantees for your system, but it works fine for me.
