Συχνές Ερωτήσεις

Q1: Can this antenna replace multiple single-band FPV antennas?
Ναί. Its ultra-wide frequency range allows one antenna to cover multiple FPV bands.

Q2: Is this antenna suitable for 5.8GHz FPV systems?
Απολύτως. It supports 5.8GHz as well as many other common FPV frequencies.

Q3: What connector options are available?
Standard options include SMA and RP-SMA. Other connectors are available upon request.

Q4: Is this antenna suitable for outdoor use?
Ναί. It is designed for reliable performance in outdoor and mobile environments.

Ε5: Do you offer OEM or custom designs?
Ναί, OEM and ODM customization services are available.

Ε6: Can a 500–8000 MHz VRX be paired with a UWB antenna for automatic scanning without changing antennas?
Yes — this antenna truly supports that bandwidth. A UWB (Υπερευρεία ζώνη) antenna is designed to operate over a very wide frequency range (often several GHz wide).

If the antenna’s rated frequency range fully covers 500–8000 MHz, μπορείς:

• Connect it to the VRX once
• Perform automatic wideband scanning
• No need to change antennas during the scan

⚠️ Practical limitations to be aware of:

• Antenna efficiency & gain will not be flat across 500–8000 MHz: → Sensitivity may be weaker at band edges
• VSWR / return loss may degrade at certain frequencies
• Polarization mismatch can affect reception
• Για καλύτερη απόδοση, narrowband antennas still outperform UWB ones in their specific bands

👉 So: functional for scanning, but not always optimal for maximum sensitivity.
