This homebrew 1.2 GHz microwave antenna is built from a 6″ household air duct and picks up a signal from an Icom R3 amateur TV repeater. The device then retransmits the signal over a longer distance. Not a lot about the construction of this giant “flashlight looking” device, but we still like the hacked efficiency of this design.
