I met with RTL-SDR quite lately, in 2015 and started enjoying a wideband receiver with extensive modes and abilities. I used to have some good HF receivers before, just for DX'ing but SDR enabled me to reach to "space" as i was astonished with the Cubesats while following Rosetta Mission.
Beginning with simple stuff, i started building antennas, from simple wire antennas to stacked yagis, mostly with recycled material and some ingenuity. I'm not an engineer but having worked with scientific methods, i found by trial and error and lots of pain, some good ways to have antennas that i can store easily, carry around by not looking like a complete freak!
In these RTL pages, i'll share as much as i can do with RTL, hoping it can help someone, particulary who are newly into the RTL-SDR stuff.
