This article was updated in June 2022, to include further information on various particles. Originally published in November 2020. ___ What is the effect of fog on a radio link? I often see concerns that fog and/or clouds will adversely affect your RF link reducing your range and possibly cut you from your aircraft. After […]
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 […]
The SMA (Sub miniature type A) connector as we know it was designed in the 60s. So, for many of us, they always been part of the landscape. Its 8mm hexagonal shape, meant to be tightened with a tool, doesn’t offer much grip to fingers. Peoples been cutting/printing contraption that fit over the SMA and […]
We designed the new micro AXII for lumenier. A move forward from the current AXII in term of miniaturization at less than half the volume of the original. By far, the smallest 5.8GHz CP antenna available right now. In order to bring the micro AXII, innovations going beyond RF engineering had to be made, such […]
Mishaps. They always happen, no one escape. When your singularity antenna is smashed by an unfortunate event, not all hope is lost! With a 3D printer and basic soldering skills you can salvage your dead antenna and turn it into a “polarizer”. First, tear away the ends caps, then un-solder the network. The elements […]
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. […]
I am extremely proud to present this whole new CP omni antenna design from TrueRC Canada.
