But even the best SDR is constrained by the antenna it’s connected to ... from space without breaking the bank: the Discovery Dish by KrakenRF. After reaching 105% of its funding goal on ...

Also called a "dish" or "mirror," parabolic antennas are used for satellite signals and planetary telescopes. The reflective mirror design can also emit energy such as in a flashlight or ...

Dipole antennas are easy to construct and deploy, but they have low gain and efficiency, and they require a matching network to reduce the reflection losses. 1) Parabolic Dish Antennas ...

My custom-built, easily transportable parabolic antenna immediately sprang to mind. The idea of a three-meter diameter parabolic dish was rejected for something a little more practical and a ...
