My homebrew coax QFH antenna

Photo was taken before some corrections were made to atnenna, big and small loops were not in clock wise direction from top to bottom (actually one of the loop was in opposite direction & produced very noisy image).

EI7BA homebrew Hexbeam antenna.

An Hexagonal Beam in 3 hours..Over the last few years, I have heard guys using Hexbeam antennas. As this antenna was new to me, I got a few of these stations to rotate their beams so I could see the front-to-back ratio. I also got descriptions as to how they were put together, how they performed etc.As I collected information from various...

Home brew hot air pencil

For my Modding my EEE PC to do Awesome Things project, I've found that I need a way to desolder really tough components from a board.
