FAQ
Q1: Does the video signal search run continuously in a loop from 500 MHz to 8000 MHz, or do I need to press the search button each time?
A1: The Wideband FPV VRX supports continuous auto-scanning. During the search process:
- If a video signal is detected, the VRX display will show a clear video feed.
- To lock onto this frequency, press the SET button. Without locking, the receiver will automatically move to the next frequency after 3 seconds.
- Pressing SET again unlocks the current frequency and resumes the automatic scanning process.
- When the scan reaches 8000 MHz without finding a video signal, it will automatically restart from 500 MHz, continuously looping through the frequency range.
- The search will keep cycling until a signal is locked manually using the SET button.
This ensures uninterrupted scanning across all bands while giving you control to lock onto any active FPV video channel.
Q: Can I connect an external device (e.g., ESP32) to the receiver to read or modify the frequency?
A: Yes, it is technically possible. Some customers have purchased samples and implemented their own custom modifications. However, please note that we do not provide technical support for such secondary development. Customers would need to handle this independently.
Q: Does the receiver support frequencies that are not included in the preloaded channel list?
A: Yes. For frequencies outside of the preloaded channel list, the receiver supports automatic scanning within the 500–7300 MHz range.
Q1: What type of video signals does 500MHz-8000MHz 8G Ultra-Wideband FPV Video Receiver support?
A1: It supports standard analog video formats NTSC and PAL and automatically detects the correct format.
Q2: Can it work with drones over long distances?
A2: Yes, depending on antenna and environment, it can receive signals up to 50 km.
Q3: What power supply is required?
A3: A regulated 12–28V DC power source is required.
Q4: Is the device safe to operate without an antenna?
A4: No, always ensure the antenna is securely connected before powering on to prevent damage.
Q5: Can I lock onto a specific channel?
A5: Yes, it allows both automatic scanning and manual channel locking for stable reception.
Q6: Can it be used in high-temperature environments?
A6: It should be used in ventilated environments to prevent overheating.
Q7: Can your VRX work with future transmitters outside the 6–7 GHz range?
A7: Yes. Our VRX frequency range is 500–8000 MHz, not limited to the 6–7 GHz band. This means future transmitters supporting a wider frequency range will still be compatible with our receivers, ensuring flexibility for long-term upgrades and diverse applications.
Q: The specification states that the receiver works from 500–8000 MHz, but the product description only shows part of this range. Can you provide the full frequency range and explain how to tune it?
A: Yes. The receiver fully supports 500–8000 MHz.

If you do not know the transmitter’s frequency:
You can use the 500–8000 MHz automatic search function to scan and lock onto the active signal. -
If you already know the transmitter’s approximate frequency:
You can enter the menu and select the closest preset frequency band, then perform a search within that band for faster and more accurate tuning.Available preset Channel options in the menu: 1.2 GHz, 1.5 GHz, 1.8 GHz, 2.8 GHz, 3.3 GHz, 3.7 GHz, 4.2 GHz, 3-4 GHz, 6-7 GH
- Check the preset frequency list for each channel.
These presets help the receiver focus its scan in the correct segment of the full 500–8000 MHz range.
Q: Does this 500–8000 MHz FPV VRX come with a remote control? so I can manually enter a frequency to search channels.
A: Currently, it does not include a remote control for manual frequency input. The receiver automatically scans channels within a preset range of commonly used frequencies. Please test the sample first. If you confirm that manual frequency input is required, we will develop this feature for you and can customize the device to support manual frequency entry for channel searching.
Q: Does the UWB VRX support automatic frequency hopping between different VTX bands (e.g. 1.2 GHz and 3.3 GHz)?
A: Although our UWB (Ultra-Wideband) VRX supports a wide tuning range from 1.2 GHz to 7.2 GHz, it can only operate on one frequency at a time.
The VRX cannot simultaneously receive FPV video signals from VTXs operating on different frequency bands, such as 1.2 GHz and 3.3 GHz. When the VTX is working at 1.2 GHz, the VRX must be tuned or scanned and paired at 1.2 GHz. If the VTX is switched to 3.3 GHz, the VRX must also be retuned or rescanned to 3.3 GHz, and the previous 1.2 GHz link will be disconnected.
Therefore, automatic recovery or frequency hopping across different bands is not supported. The VRX supports frequency scanning and tuning within the same band, but it does not support cross-band operation or simultaneous multi-band reception.
Q: What is the gain of the UWB antenna? Is it omni or directional?
A: The default configuration uses a directional antenna with a gain of 6 dBi. You may also use your own antenna. For optimal performance, it is recommended to use a narrowband antenna optimized for your target frequency range—for example, antennas designed specifically for 6.1–7.2 GHz can provide lower VSWR and higher gain than a general-purpose UWB antenna.
Q: Do you offer multi-frequency fusion VTX/VRX that combines two signals into one stable image?
A: Currently, our FPV VTX and VRX systems do not support cross-band operation. Even with a high-power amplifier (e.g., 5 W+), it is not possible to achieve 50 km range using analog 1.2 GHz systems.
For extended range and stable cross-band operation, we recommend using our digital video transmission solutions. These systems support frequency hopping across bands, interference avoidance, and can maintain clear image quality and reliable links over distances of 50–200 km.
Q: Can I remotely change the frequency of this FPV drone repeater?
A: Currently, the frequency must be adjusted manually using the buttons on the receiver and the on-screen parameters. If remote frequency control is required, your software engineer can implement it by reading the frequency-setting commands and connecting a microcontroller. Through a 100-meter Ethernet connection, the frequency adjustment commands can be transmitted remotely, allowing the operator and the remote controller to stay in a safe location while modifying video signal settings.
Q: I want to receive good signal strength from a drone without knowing its exact direction. Can I use an omnidirectional antenna for this purpose?
A: Currently, there is no single omnidirectional antenna that can cover an extremely wide frequency range from 500 MHz to 8 GHz. To achieve full coverage across the receiver’s frequency range (1.2–7 GHz), engineers recommend using four separate receiver units, each with its own omnidirectional antenna, tuned to different frequency bands.
Recommended Setup:
| Frequency Range | Antenna Type | Quantity | Approx. Length | Typical Gain |
|---|---|---|---|---|
| 1.2 – 1.8 GHz | Omnidirectional | 1 | 200 mm | 2–3 dBi |
| 2.8 – 3.3 GHz | Omnidirectional | 1 | 150 mm | 2–3 dBi |
| 3.7 – 4.2 GHz | Omnidirectional | 1 | 150 mm | 2–3 dBi |
| 6 – 7 GHz | Omnidirectional | 1 | 150 mm | 2–3 dBi |
Notes:
- Each antenna covers a specific frequency range with relatively low gain.
- Using multiple antennas ensures the receiver can maintain omnidirectional coverage without needing to know the drone’s direction.
