Every now and then, someone asks why not connect two antennas together using a Tee or Y adapter for the benefits of both? The answer is that isn’t that simple unfortunately. Unlike batteries that, given they are same voltage, you can wire them together for more available power, antennas produce an alternating current. As […]
Above is a radiation pattern from an omni directional antenna (AXII) typically found on aircraft transmitter. The usual dBi unit been replaced by ratio of maximum range. You may ask why we didn’t simply marked in meters or kilometers? Because the ultimate range depends on a lots of others factors than one antenna. However, keeping […]
Developed in conjunction with ADCORE magnet systems, the Pharos is a new smart antenna
Team black sheep been doing some great work lately with their new “crossfire” long range system. The current generation of 433MHz “LRS” have served us well, but where plagued by common issues. Notably, the on-board noise coming from different equipment within the aircraft. That super nice camera, with amazing colors, but cut your range completely, […]
Analog video signal is a very important part of FPV yet little is posted about it. I’m writing this article in hope to shed some light on how the camera’s image is transformed into an electrical signal and the other way around. I’ll describe the basic black and white composite video signal. “Composite” because it […]
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 ships, as long as everything is connected and no smoke is released, they believe its fine. This is not true…
