Therefore, its important to choose an antenna that can withstand the inevitable abuse it will take, especially if you crash often. 95% of the time we use 5.8Ghz for FPV video so in the rest of this article we will assume all the antenna are 5.8Ghz. You can, but shouldnt. Its also important to use a rigid antenna, since a longer antenna can create vibrations during flight that make it harder to tune your drone or cause more noise. The DJI FPV camera lens for the air unit has a focal length of 2.1mm which works fine, but the RC18G lens has a focal length of 1.8mm which gives you an even wider field of view to be able to see more in the frame. Antenna gain can alter the radiation pattern, which can be seen in the antennas datasheet. A monopole antenna is the simplest form of antenna, consisting of an unshielded solid wire that acts as the antenna element. Skew-Planar Wheel, Cloverleaf, and helical antennas are examples of common circularly polarized antennas. LHCP is not compatible with RHCP, so if using circular polarized antennas you need to make sure that both the transmitter and receiver both have either RHCP or LHCP antennas. Linear polarization is used in many basic antennas, such as the stock dipole antennas that come with your VTX and VRX, or even in your home WiFi. Pagoda is a relatively new antenna design in the FPV scene, released in 2016. Its not unheard of for some racers to use a dipole antenna on the drone for weight saving and durability while using a circular antenna on the video receiver. They are however relatively fragile therefore often come in different cases and protection. When choosing FPV antenna for FPV drones its important to consider its durability.

Flat Panel "Max Range" Antenna: 4 - 6 Miles Range. Urmia is situated at an altitude of 1,330 m above sea level, and is located along the Shahar Chay River (City River) on the Urmia Plain. In general linear polarization can provide extra range as all the energy is focused on a single plane rather that being dispersed into a cylindrical pattern. Typically onboard your aircraft you will always use an omni directional antenna since its always rotating but you can use a directional antenna on the ground that will need to always point at your aircraft to get extra range. I assume its the direction the wires are formed but which view is the correct one? 95% of the time we use 5.8Ghz for FPV video so in the rest of this article we will assume all the antenna are 5.8Ghz. Cheaper to manufacturer as you can print them on circuit boards and their quality would be roughly the same.

It has a strong case which protects the antenna in hard crashes. For example, an RHCP antenna might output 90% of RHCP signal with 10% LHCP signal. The unique design and use of materials (PCB) make it very durable. A dipole antenna has a simple design, consisting of two equal-length elements that are perpendicular to each other, typically in a straight line. If youre relatively new (6-8months) to drones/racing, then Id just stick with what youve got, and maybe a decent set of CPL antenna. Please don't hesitate to contact us. A perfectly isotropic antenna with 0 dB gain will have a radiation pattern thats a perfect circle from the antenna. Over the last few years Ive accumulated a few of these circular antennas How can I tell the direction of polarisation RHCP / LHCP ? Use high-quality imported silica gel to redefine the internal structure and achieve subtle shock absorption. Unfortunately in the EU the only way to can possibly get through a wall is to use a directional anntenna to focus energy in one direction, I am not sure about entire EU, but in the UK we are limited to 25mW power for 5.8Ghz airborne video equipment. There is no difference in performance. They are relatively inexpensive to manufacture as they can be printed on circuit boards, but their efficiency is inherently lower than that of other types of antennas that use air as dielectric, such as the helical antenna. =), Best option will be TBS Triumphs ( I found pair for 20$ on china shops) another good option is pagoda 2 antenna (same shop, price ~14), Power of transmitter (power of receiver is less important, right?
