Omni vs. MX-air
The MX-air sits on the line between directional and omni-directional antennas. When aimed vertically, it provides all-around coverage like an omni but eliminates the null zone on top, making it [...]
The Pagoda
The Pagoda antenna by Maarten Baert became a popular open-source FPV antenna. In this post, we study its inner workings through 3D EM simulation and analyze how different protection methods like [...]
Antenna comparison chart.
This comparison chart shows a top-down view of the coverage and estimated range for different TrueRC antennas at 200mW transmitter power, including range figures at 90 degrees off beam for [...]
SWR and S11: What it means?
S11 (return loss) is another expression for SWR and arguably a better one. This article explains the relationship between SWR, radiation efficiency, and actual range, showing why low SWR alone [...]
Salvaging your singularity into a polarizer.
When your Singularity antenna gets smashed, not all hope is lost. With a 3D printer and basic soldering skills, you can salvage it into a circular polarizer that converts any linear dipole into [...]
Antenna Patterns: part 1/2 "Omnis"
This guide explains omni-directional antenna radiation patterns using the AXII as an example. Learn how antenna orientation and null zones affect your FPV range, and discover the best mounting [...]
3D EM simulation at TrueRC Canada
TrueRC Canada has upgraded to the latest 3D EM time-domain simulation tools for faster and more precise antenna development, covering everything from wire antennas to complex 3D structures and [...]
The new TBS crossfire
Team Black Sheep made waves with their Crossfire 900MHz long range system, solving the noise issues that plagued 433MHz LRS. Here is a hands-on review including a custom Moxon antenna build and [...]
RF link budget
In this article, I’m going to explain the RF link «budget». Where is that budget, how it can be calculated and what affect it for better or worse. Your budget is spread over 3 things: Tx power, R [...]
Analog video signal
Analog video signal is a very important part of FPV yet little is posted about it. This article sheds light on how the camera image is transformed into an electrical signal, covering composite [...]
FPV wiring tech.
This is a follow-up of my article on video signals. I continue on what can affect your FPV experience, mostly what can affect the video quality. Many people neglect the wirings of their FPV [...]
