Antennas are some of the most critical components of your FPV/LRS set up. A well-constructed, high-gain antenna can dramatically improve your performance for your long-range-rc system (“LRS”). The “Sander” style antenna is a simple monopole style design, with a SMA connection. This has proven to outperform stock duck antennas that have the element coiled to make it a more friendly form factor. The “Sander” antenna is used as the OEM on ImmersionRC gear and is a direct replacement or makes for a great upgrade to other 433Mhz systems or telemetry radios.
