New milestone for ExpressLRS: Wezley Varty explain how he and his team reached 100km flight distance with ExpressLRS control and telemetry system. Note: The sniper dish feed wasn’t LHCP to account for the reflection of the dish so video would probably been solid for the whole flight if that been the case.
I often get asked on which channel X or Y antennas are tuned too. The short answer is: There’s no such thing as a tune so specific that it encompass a single channel, for hobbyist at least. The long answer is a perfect tune on a certain channel won’t make any difference as the bandwidth […]
The pagoda antenna was developed by Maarten Baert as a free to use design. It quickly became a popular antenna, with multiple brands selling them as is or with various attempts to encase or otherwise protect it. In this post we will study the inner functioning of the pagoda and what are the effects of […]
S11 (return losses) is another expression for SWR (standing waves ratio) and IMO a better one. It is the ratio of port #1 to port #1, in other words, what comes out of port #1 relative to what you injected in port #1. When you send power to an antenna, some of it is reflected […]
Thanks to the FPV community’s strong support, we continued R&D work on our ever popular directional CP antenna line on 5.8GHz, namely, the X-air 5.8, X²-air 5.8 and gatling 5.8. The results comes in more available circularity in the 5.8GHz region and even down to 5GHz! Circularity is also further increased at the beam’s edges. […]
