Several improvements over other brands including use of the R820T2 tuner, improved component tolerances, a 1 PPM temperature compensated oscillator (TCXO), SMA F connector, aluminium shielded case with thermal pad for passive cooling, activatable bias tee circuit and a much improved antenna set. Can tune from 500 kHz to 1.7 GHz and has up to 3.2 MHz of instantaneous bandwidth (2.4 MHz stable). (HF reception below 24 MHz in direct sampling mode). Please note RTL-SDR dongles are RX only. The multipurpose portable dipole kit is great for beginners! Use it either for terrestrial or satellite reception just by changing the orientation of the antenna. The mounts and extension cable allow you to temporarily place the antenna outside for improved reception.
