The Complete Guide To Best FPV Antennas

All antennas on this page have been thoroughly tested. Each antenna was tested under controlled conditions and the results have had a great impact on what I consider to be the best FPV antennas.

Best FPV Antennas Review

It is very difficult to decide which is the best antenna actually. It is not just the antenna that can be blown farther – there is much more to it than that.

By looking at these antennas and deciding which ones to put on my top 5, I took into account my own experience, other people’s experience, how far they flew, the quality of their reception, the number of frames that were reduced, etc.

While the results They will never be perfect, on this page you will find one of the most complete sources of information that explains what the 5 FPG 5.8 GHz antennas are in 2017.

The complete guide to Best FPV Antennas

The frequency of the antenna

The FPV antennas are tuned to specific frequencies, so you can not use a 2.4 GHz antenna with 5.8 GHz FPV devices. In general, the lower frequency antennas are larger than those of the larger frequency.

FPV Antennas
Polarization antenna – linear or circular

The first concept you need to understand is the polarization of the antenna. There are two main categories of antennas, linear and circular polarized antennas.

The above image may seem rather confusing, but the radiation pattern for linear (left) and circular (right) antennas is shown. The most important thing to note in this picture is the red plane in each diagram. In the case of linearly polarized antennas, the signal is formed in a single plane (the red plane in the image). For polarized circular antennas, the components are combined into a signal in a circular corkscrew (red cylinder in the image). The blue and green waves are the horizontal and vertical components of the signal that make up the combined signal in red.

Linear or Circular

When we speak of polarized circular antennas, we obtain left circular polarization (LHCP) and right circular polarization (RHCP) antennas. This simply extends in the direction of the corkscrew signal emitted from the antenna. LHCP is not compatible with RHCP. Therefore, if you use circular polarized antennas, you must ensure that both the transmitter and the receiver have RHCP or LHCP antennas.


When to use circular polarization

For most unmanned aircraft applications, it is best to use polarized radio antennas
If you perform acrobatic flight or you do not stay exactly the long term level of your flight.
When using linear polarized antennas

They do not have enough space to mount a circularly polarized antenna
If your plane becomes very stable (like a slow flight photo quadricycle) and you want to get more rank. This means. If your antennas are on the ground and the aircraft is up most of the time

Use of multiple antennas

To get the best of both Wolds, some FPV systems combine two (or more) antennas into the ground receiver. This could be an omnidirectional antenna to give you good coverage. And the second antenna could be a high-power directional antenna to give it an additional range in a particular direction. These systems use dual-receiver systems (so-called diversity receivers), which monitor the signal from both antennas and change to the one receiving the best reception.

Which antennas should I use for FPV?

I would say the best antenna to start with would be a clover antenna on your receiver and a flat antenna on your twisted video transmitter. Some FPV kits already contain these antennas, but if not most shops will sell them as a pair of FPV 1.5k antennas. These are omnidirectional, circularly polarized antennas that work well for FPV.

In general, the price gives a good indication of the quality and precision of the antenna. When comparing the same type of antenna from different manufacturers, the most expensive will usually have a better range. This is because they are made with better materials and more precisely. However, this is not always the case and it is up to you if you think that it is worth paying twice to get a 10% increase in the range.

As you fly with FPV and you want more range you can upgrade to more directional systems like a helical antenna.

Types of antennas

  • Enter – Linear, Omnidirectional
  • Skew Planar – Circular, omnidirectional (4 lobes)
  • Cloverleaf – circular, omnidirectional (3 lobes)
  • Array – circular, omnidirectional
  • Directional FPV antennas.jpg1471x551 113 KB
  • Helicoidal – circular, directional
  • Patch – can be either circular or linear, directional
  • Needles – circular, directions
  • Yagi – Linear, direction

What is the Gain?

The gain of an antenna is simply the performance of an antenna or a video transmitter, measured in decibels, the formal definition is:

The decibels (dB) is a logarithmic unit that expresses the magnitude of a physical quantity (usually power or intensity) relative to a specified or implicit reference level.

Let’s meet Johan Lozano, the 2011 World Champion in F3N. Johan has also been the 2010 European Champion in F3N, and a five-time national winner of the German F3N competition. F3N is a brand new RC helicopter competition category formed under the Federal Aeronautique Internationale. He is 64 years old and He is a carpenter by trade and He lives near East Bayberry Street Hanford, United States. He started flying in 2001 with a Raptor 50.
