They have to be the correct length so that the RF wave reaches it's end - at the end of the antenna. Part 2: Because antennas are fed with RF energy of a certain frequency, the conducting elements of the antenna have to be "resonant". Most times, you Want a lower signal to the rear. This is called the "Front to back ratio" - and is also in DB. You don't get something for nothing! The signal is reduced to the rear. The more you concentrate the power in one direction, the narrower the signal's "Beamwidth" becomes.like focusing a flashlight or hose. You design them to make the pattern you desire. ALL antennas have a "pattern" that is not equal in all directions. This DBi gain is compared to an imaginary pin-head antenna that has a perfectly even radiation pattern - like a 360 degree sphere. It's more complex than that.Īntennas are rated in "DBi gain". And they don't just take the rear 180 degrees of radiated power - and face it forward. Antenna designs don't amplify the signal, they concentrate it. As you might imagine, it reflects the radiated RF from the controllers antenna - towards a forward direction instead of 360. Part 1: The current reflector design is whats called a "Corner Reflector" or "Parabolic Reflector" antenna. I'll offer easy to understand theory here too- so folks can grasp exactly what is going on - and use these reflectors to the best advantage. It's likely that the various basic designs of the ones out there are within 20% of a perfect design. We can do a full analysis of the antenna's "gain" and "pattern". Thing is, I can tell from it's design that nobody has really put the calculator to optimizing it. The Windsurfer style antenna boosters were a great idea for the Phantom series. Signals / antennas / transmitters / receivers. I'm a new P3P owner and it's a rainy day. So don’t settle for homemade projects or low-grade knockoffs.Hey guys- ( pre-apologize for the length of this- but it might be useful) Our Phantom 4 Long Range System is currently an Executive Kit exclusive, though it will soon be offered as a separate upgrade. That means no need to deal with pesky cables, separate batteries, or the labor of installing dozens of parts! Exclusively at Drone World Like our Phantom 3 Range Extender, our Phantom 4 system is 100% internally powered and installed by our technicians. Sure, having a stronger, clearer signal is great, but the convenience of our Long Range System goes beyond that. Just have a look at the video above to see award-winning National Geographic photographer and videographer Max Siegal do just that. While the DJI system can result in a minimal range of around 1 mile, Drone World’s FireBridge system easily doubles that, with some expert range-mongers pushing it well beyond the 5-mile mark. Our new Long Range System pushes boundaries from 3 miles all the way up to 5. DJI's official max range is accomplished under “optimal” conditions, which most pilots are not likely to enjoy. That’s because the factory system is vulnerable to uneven terrain, natural obstacles, certain alititudes, and WiFi interference. While DJI advertises a 3.1-mile max signal range, most Phantom 4 pilots report max ranges of as little as 1 mile. It combines a class-leading antenna with 180-degree panoramic signal range, premium RG58 military-grade wiring, and top-notch WiFi boosters, hand-assembled by Drone World’s tech department. But how does one make a great system even greater? Introducing FireBridgeįireBridge is Drone World’s own upgraded, internally powered system, one that utilizes only the best, most proven technology. With a new, fourth generation of Phantom comes the need for a new generation of Range Extender. The Drone World Phantom 3 Range Extender was a major breakthrough and best-seller in the industry. ONLY System w/ Fully Internal WiFi Boosters
