Hi,
I was just wondering if anyone's using the stock RTL-SDR dongle whip antenna for their ADS-B reception. If so, what kind of range are you getting? I get reception consistently out to about 300 km with my trimmed (69 mm) stock antenna in directions that aren't blocked by nearby buildings (the antenna is next to the window in my house and not particularly high up).
I've also been reading about quarter wavelength antennas needing to have ground planes - for the dongle's whip antenna, is it enough simply to place its magnetic base on a piece of metal? Or does the metal ground need to be connected to the antenna somehow?
I've also read of others trimming their whip antennas down to 65 mm, but I calculated the quarter wavelength for 1090 MHz to be 69 mm, so I'm not sure if I should be trimming it down further.
I've also tried building collinear antennas from RG6 coax based on designs I've seen online, but so far, the dongle's whip seems to be performing the best for me somehow.
Thanks in advance for any responses =).
