RabbitEARS™ Dual Band antenna signal booster (range extender) is designed to take full advantage of DJI's OcuSync 2.0 by supporting the new automatic band hopping between 2.4 and 5.8 GHz frequencies, which maintains the strongest signal available during flight. This also eliminates having to manually set the band (2.4 or 5.8 GHz) in the DJI Fly App according to which antenna signal booster is being used, and physically switching and carrying two sets of antennas for different environmental conditions (urban/rural).

 

 

For improved signal strength RabbitEARS™ Dual Band antenna signal booster uses patented micro/mini pin technology suspended in an extremely low density foam body, which provides greater accuracy in it's frequency response and less signal blockage, for the DJI Mini 3, Mini 2, Mavic 3, Mavic Air 2 and Air 2s controller antennas. If we take a closer look at the DJI antenna below, it is unusually thick unlike previous DJI drone antennas and inside there are two elements instead of one. The front element is the driven element connected to the wiring of the controller and the back element reflects the signal back to the front element and is called a reflector. These elements are familiar to Yagi-Uda antenna designs which also have director elements in front of the driven element. Since the DJI controller antenna already has a reflector element it doesn't benefit with an additional one behind it, and can only benefit with director elements added in front of the driven element.  The director elements must be properly spaced (progressively) and tuned in length for the controller/drone, and made with special polished alloy to reduce electrical surface resistivity for optimal performance, unlike existing antenna boosters.  Patent 10910730 and patent pending.

 

To attach each antenna booster align the slotted end up to the side of the DJI antenna and the alignment slot with the rubber phone pad holder, then slide into place as shown below and press the antenna booster to secure in place. Each antenna booster can be used on either side of the antenna. For the best performance, make no changes to the default Fly App transmission settings (Dual-band, Auto). If there is little improvement, under "transmission" set the frequency to "5.8 GHz" (in Auto) then immediately back to "Dual-band" (in Auto) with the antenna booster attached.  This will start "Dual-band" on 5.8 GHz for the least interference and automatically change according to the best frequency for use with the antenna booster.
