You often hear “higher gain antenna has longer range”, but don’t be fooled! Antennas doesn’t amplify radio signals, but rather just changes the radiation pattern, which is a trade-off between coverage and range. Antenna gain is a reflection of the maximum range you can get.
Long range radio systems using 900MHz including the Frsky R9M and TBS Crossfire typically use a single dipole antenna on the receiver. The optimal antenna positioning can be different from traditional 2.4GHz systems with diversity monopole antennas on the receivers.
FPV antenna is the deciding factor that determines the range and signal strength of your FPV system. This guide will explain the basics of 5.8Ghz antennas used on mini quad VTX and VRX, and hopefully it will help you choose the best FPV antenna.
I have been using the Menace Invader Patch antenna for over a year now and like it a lot! Not only it’s one of the cheapest patch antennas on the market, the performance is also pretty good! So I have high hope for the latest Pico patch antenna from Menace RC.
OWLRC recently came up with a compact and affordable SWR meter that can measures 5.8GHz antennas performance, well, roughly. It has a simple UI, a bright touchscreen and powers off a 3S LiPo battery.
If you accidentally damage your 2.4GHz receiver antenna in a crash or by spinning propellers, don’t worry! You can easily fix it without buying a whole new receiver or replacement antenna. And there are considerations about the length of the antenna you should know about.
Antennas for FPV can be categorized by their polarization: linear and circular. In this article we will discuss the differences between linear and circular polarized antennas.
Pagoda Antenna is a new antenna for 5.8Ghz FPV system (VTX/VRX) in 2017! We will explain what Pagoda antenna is and what advantages they offer? I also bought a pair of the Realacc Pagoda antennas to test out.
SMA, RP-SMA, MMCX and U.FL are the three types of connectors widely used in FPV transmitters, receivers and antennas. This guide explains the differences to help you avoid getting incompatible equipment. The gender of SMA and RP-SMA connectors are just as confusing.
In this post we are testing some high quality, hand made antennas from a maker in Germany. They are made for racing mini quads and crashes, and offers tuning to user preferred frequency.
The ProDrone FullSet is a set of diversity-ready antenna, precision-made . Let’s have a look at how they perform on a diversity receiver.
