RTL-SDR Blog V4L dongle
Details
The V4L is the latest entry-level SDR (Software Defined Radio) from the well-known brand RTL-SDR Blog. Covering the frequency range from 500kHz to 1.766GHz, the unit works as a wideband radio scanner, so hobbyists can listen to amateur radio, track aircraft and ships, receive weather satellite images, and much more. Additionally, the built-in upconverter allows better reception of shortwave radio.
At Eleshop, we sell the original version. Therefore, the unit has multiple advantages over its counterfeits, such as a software-switchable bias tee to power e.g. an active antenna, a TCXO that keeps the radio accurately tuned, and a lower sensitivity to outside noise. To check whether the unit is the original one, visit the official RTL-SDR Blog website. We also sell this unit with an antenna kit.
