The NESDR SMArTee XTR is a premium RTL-SDR receiver built around the E4000 tuner, covering roughly 65 MHz to 2300 MHz with a small gap near 1100 MHz. Its standout feature is an always-on 4.5V bias-tee that powers inline amplifiers and other RF accessories without hardware or software changes, protected by a self-resetting fuse. A 0.5PPM TCXO keeps it stable, and the brushed aluminum case doubles as a heatsink. It suits hobbyists who want to receive weak signals at 1500 MHz and up, where the E4000 beats common R820T-based dongles, but it costs more and needs a computer and software to use.

Owners of Nooelec's E4000-based SDRs generally praise the stable tuning, cool running and the convenience of the built-in bias-tee. Some note the E4000 is less sensitive than R820T2 dongles at lower frequencies and point to the gap near 1100 MHz.
The Nooelec NESDR SMArTee XTR is an RTL-SDR (software-defined radio) designed, developed and fabricated by Nooelec in the USA and Canada. It has an extended tuning range of approximately 65MHz to 2300MHz, with a small gap near 1100MHz. It uses an E4000 tuner, which has better sensitivity at 1500MHz than R820T-based devices.
An integrated, always-on 4.5V bias-tee supplies up to 250mA to power RF accessories, with no hardware or software modification. An automatically resetting fuse protects the bias-tee against accidental short-circuits of the RF input.
The radio is housed in a silver brushed aluminum enclosure with an integrated custom heatsink. This bundle includes an antenna base with cable and three antenna masts.
