RTL-SDR Blog V4L + antenna kit
Details
The V4L with a dipole antenna kit 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 track aircraft and ships, receive weather satellite images, and much more. Additionally, the built-in upconverter improves shortwave reception, and the dipole kit allows outdoor mounting for stronger signals.
At Eleshop, we sell the original version, which has multiple advantages over counterfeits, such as a software-switchable bias tee, 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 as a dongle only.
