WHOOVER 2 (pronounced as whoover) is a portable device for detecting and intercepting analog video signals from FPV drones and some fixed-wing UAVs in the 1.2 GHz and 5.8 GHz bands.
WHOOVER 2 has only 2 receivers — one for each band, not two per band as in WHOOVER 1. This means that while video is being broadcast, the current band is not scanned further because the receiver is working to receive video. The other receiver works normally at this time, scanning its band.
Install the included antennas on the corresponding connectors and turn on the device using the switch on the top panel — scanning will start automatically.
The device is intuitive to turn on and operate: simply switch it on and it automatically starts scanning all bands in search of analog video signals.
On the small screen, the device displays two histograms for the corresponding bands. Each one shows the start and end frequency of the scanning range in MHz.
By default, band scanning starts from the minimum operating value, but in the settings you can change the start and end points of the scanning ranges.
If the device cannot find any signal within its range, the screen will display the corresponding message — “Сигнал не знайдено” (Signal not found).
Once a signal with video is found, its frequency and level as a percentage will be displayed on the small screen, the device will emit a sound signal, and the intercepted video will begin streaming on the large screen. The signal streaming video is highlighted with a blue background.
The 🔼 and 🔽 buttons allow you to move through the signal list and switch video streaming between signals. These buttons also allow navigation through the device menu in menu mode (режим меню).
The 👁️ button allows you to turn the video screen on/off. When you turn off the screen, the blue highlight of the active signal will disappear accordingly.
Each signal can be marked as “friend” (свій), so the scanner will not react to its appearance and will not emit a sound signal if one is enabled. To mark a signal as “friend”, use the 🔼 and 🔽 buttons to navigate to the signal and hold the 👁️ button — the signal will then receive a green frame.
To remove the “friend” mark from a signal — similarly, hold the 👁️ button until the frame disappears.

Navigation through menu items is done using the 🔼 and 🔽 buttons. To change the value of the selected menu item, press the 👁️ button.
To exit the menu, select the item (>Save) and press the 👁️ button.
By default, the device comes with the Sound menu item enabled (shown as “Звук” on screen), but you can disable it if needed, and then the device will find new signals “silently”.
To disable the sound notification when finding a new signal, enter the menu, select the Sound item (Звук) and press the 👁️ button — the checkbox on the left will change its value.
After this, select the item (>Save) and press the 👁️ button.
Enter menu mode (режим меню) and select the Ranges item (Діапазони).
The number of scanning cycles during which a signal is considered active.
If a signal existed for fewer scanning cycles than specified in the Station Lifetime parameter, the signal is considered lost and a countdown begins for its removal from the signal list.
This option will be useful if your small screen has a white background and this makes it difficult to work with the device in the dark.
Select this item and save the settings — inversion will make the background dark.
The device performs self-diagnostics of key components each time it is turned on:
If any of them is not working, a red frame will appear around the small screen.
To understand what went wrong:
In case of an error, the screen will indicate what exactly is not working properly. In such a case, you should contact the supplier.
In normal operating mode, there should be no errors.
On the top of the device, there are marked SMA connectors for antennas at 5.8 GHz and 1.2 GHz respectively.
Install antennas according to the markings. Tighten the antennas firmly but not too tight, so as not to damage the connectors and the board.
The device requires two omnidirectional antennas:
No antenna exists that offers a good radiation pattern, decent gain and SWR, a compact form factor, and coverage of the wide frequency bands supported by Whoover receivers.
On the other hand, the enemy’s practice of using video transmitters and the UAV piloting style creates a favorable situation for video signals to be intercepted even with satisfactory antennas. Of course, such antennas have disadvantages: sometimes an inconvenient form factor, imperfect radiation pattern, relatively weak signal amplification, etc. But there are also advantages: they are compact, affordable, and they work!
Depending on the direction, statistics of enemy UAV frequencies, and the overall situation, you can select antennas that can significantly improve your signal reception quality and range. Pay attention to the antenna connector — it must be SMA male.
SMA male antenna connector — has a characteristic copper pin inside.
WHOOVER 2 is built on RX5808 receivers and a TA8804F+TA1322FN tuner.
To update the firmware, you need a Wi-Fi access point (2.4 GHz) with the following parameters:
The Firmware menu (Прошивка) shows the current firmware version on the device and the data for configuring the Wi-Fi access point. If you have configured the access point, select the item (>Update) to start the update.
Improved sensitivity of RX5808 rev *901 modules, which significantly improved video detection speed in the 5.8 band.
Added product diagnostics option. You can find it in menu Advanced (Розширені) → Diagnostics (Діагностика).
Added support for another type of screen controllers, which expanded manufacturing capabilities.
Added support for small screen color inversion. If your small screen has a white background that hurts your eyes, now it’s easy to fix: Advanced (Розширені) → Invert color (Інвертувати колір).
Extended scanning range. New ranges:
