Many different manufacturers sell their own RTL-SDR, including antennas whatever, they may also sell upconverters to access even smaller bandwidths, im using the NooElec NESDR Smart https://www.nooelec.com/store/sdr/sdr-receivers/nesdr-smart.html and the Ham-It-Up upconverter https://www.nooelec.com/store/sdr/sdr-addons/ham-it-up-304/ham-it-up-plus.html - also open source hardware

https://airspy.com/download/ - SDRSharp (SDR#): Probably the simplest SDR software out there, supports RTL-SDR and many plugins exist, some software are also compatible with it - open source (A LOT of SDR stuff is open source)
