A transmitter module on the aircraft takes the gimbal camera feed and a receiver at the ground station drives the monitor, so the picture comes down live. Long-range work uses the 300-1000 m tier, tuned for low latency. Resolution depends on the model, not the range, so the long-range tier still runs 4K60.
During inspection or aerial work the aircraft is hundreds of metres from the ground station or more. Once link margin runs out the picture stutters, breaks up or drops, and the operator either brings the aircraft back closer or waits to review the card after landing.
When the ground picture trails reality, framing, focus and tracking turn into guesswork and the gimbal overshoots. Inspection means holding on a defect, and noticeable lag turns every hover and framing adjustment into several attempts.
The airframe has little space for a video link, and every extra gram counts against payload and flight time. A boxed off-the-shelf transmitter is bulky, adds cabling and needs its own mounting and power.
As the aircraft turns and banks, the frame, battery and gimbal come between the antenna and the ground station and the signal swings. If antenna placement was not planned in the design stage, it is hard to fix later.
Long-range downlink uses the 300-1000 m wireless tier on 5 GHz and link rates up to VHT40 (802.11ac). The figure assumes line of sight; antenna placement, airframe material and local interference all affect it, so confirm real range with a sample on a test flight.
This setup puts low latency first, so the ground picture follows the gimbal and aircraft closely and framing and tracking are easier to judge. Embedded HDMI audio travels with the picture, and the RX returns the monitor's real EDID to avoid black screens and forced resolution drops.
The transmitter module is 22 × 45 mm and plugs into your own carrier board through an 80-pin edge connector. Shape the board around the space inside the airframe, its mounting points and the camera interface, instead of strapping on a boxed transmitter.
The 300-1000 m tier is a two-antenna 2T2R design, so the carrier board needs two antenna connections and the antennas can be mounted outside the airframe. Separate the two antennas at the design stage to reduce blocking by the frame, battery and gimbal as the aircraft turns.

Cabling hassle and adapter chaos in meeting rooms, especially with BYOD guests.
View solution →KVM ExtensionThe host must live in a rack or server room while the operator sits tens of metres away.
View solution →Film & BroadcastCameras move constantly while director, focus puller and client all need the same feed.
View solution →Portable DisplayPortable monitors still need an HDMI or Type-C cable to the source, which gets in the way when moving around or sharing the screen.
View solution →Wired & FiberBetween buildings, across a site or in heavy RF interference, wireless cannot reach and HDMI cable cannot run that far.
View solution →Pro DisplayWorkstations, graphics cards and pro monitors mostly use DisplayPort. Going wireless means stacking DP-to-HDMI adapters, which is messy and hard to keep compatible.
View solution →Mobile CastingLaptops, tablets and phones often have only USB-C, so casting starts with hunting for an adapter, and guest devices in meeting rooms and showrooms vary widely.
View solution →DockingLaptops have few ports, so monitors, keyboard and mouse, Ethernet and charging all need adapters, and casting in a meeting room means carrying yet another dongle.
View solution →In-Car ConnectivityThe head unit only supports wired CarPlay, so the phone has to be plugged in every trip, and rear passengers end up passing phones around to share content.
