40m OCF Spiral Dipole
This antenna is an off-center fed spiral dipole for 40 meters, based on KN9B’s spiral dipole
Archimedean Spiral Antenna for RTLSDR
An Archimedean spiral made of two equal lengths of coaxial cable seems to be the easiest circularly polarized antenna to make that'll cover a broad range of the rtlsdr dongles' E4000 tuners
