Antenna Performance Comparison for the RTL-SDR

Akos from the SDR for Mariners blog has put out another post this time comparing various antennas cut for 121 MHz with the RTL-SDR. He tests monopole, dipole, two radial and rubber ducky antennas on their signal to noise ratio performance on an ATIS signal in SDRSharp.

It is important to note that different antennas will have different gain directionality, so your own experimentation may still be required for your own RF environment.
