This should have given a clear and strong signal, but alas, the signal was very weak. The experiment started as an attempt to receive a DVB-T signal centered around 506 MHz, from a mast about 10 miles away. If there are real antenna specialists reading this, they are encouraged to do a more thorough writeup on the exact mechanism of a monopole-based corner reflector antenna, as there was little information to be found on the internet. The reader is pointed to the fact that corner antennas are based on a Dipole, where the stock RTL-SDR antenna is a Monopole, so some adjustments will have to be made, which is discussed and explained later in this text. the stock RTL-SDR antenna. To keep this tutorial concise, the reader is encouraged to study the Wikipedia pages for details about Corner Reflector Antennas, Dipoles and Monopoles.Ĭorner Reflector Antennas are very easily constructed from 2 A4-sized cardboard panels, covered with tinfoil. This allows for a foldable and transportable external reflector to the built-in wifi antennas of a laptop, which are located on the upper corners of the display. This tutorial will discuss the use of a Corner Reflector with a monopole antenna, i.e. We are posting his write up and results below: The reader had built a corner antenna reflector in order to improve reception in one direction. Last week a reader of wrote into us to let us know about some experiments that he had been performing with the telescopic stock antennas provided in our RTL-SDR dongle packages.
