Συχνές Ερωτήσεις

Q: How do I use this antenna and which direction should it face?
ΕΝΑ: Για βέλτιστη απόδοση, aim the antenna so that the top horn opening (the front/open side) is directly facing your FPV drone (πομπός). This side is the primary signal reception direction and provides the strongest signal.

Avoid pointing the back side of the antenna toward the drone, as it has significantly weaker reception. Για καλύτερα αποτελέσματα, keep the antenna aligned with the drone’s position during flight to maintain a stable and clear video signal.

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.

Vivaldi broadband directional antenna

ΕΝΑ Vivaldi broadband directional antenna is a type of high-performance antenna designed to operate over a wide frequency range while focusing its radiation in a specific direction. It features a tapered slot structure that enables stable signal transmission across multiple frequencies, making it ideal for applications that require both bandwidth flexibility and directional coverage. Compared to conventional antennas, it offers higher gain, better directivity, and consistent performance over a broad spectrum. This type of antenna is commonly used in wireless communication systems, ραντάρ, microwave imaging, and ultra-wideband (UWB) εφαρμογές. It is particularly suitable for scenarios where long-distance signal transmission, υψηλή ανάλυση, and precise targeting are required.
