Installation Notes
This is a directional antenna. For best performance, orient its receiving face toward the intended signal source. Confirm the antenna's frequency range, RHCP polarization, and connector compatibility with your equipment before installation.
RHCP antennas generally work best with matching RHCP antennas at the opposite end of the link. Actual performance depends on transmitter power, receiver sensitivity, installation, obstacles, and the surrounding RF environment.
FAQ:
Q: What frequency range does this antenna support?
A: It operates from 3000 to 3800 MHz.
Q: What does RHCP mean?
A: RHCP stands for Right-Hand Circular Polarization. It is commonly used in compatible FPV and wireless communication systems.
Q: What is the antenna gain?
A: The nominal gain is 10 dBi, with a peak of 10.6 dBi at 3400 MHz.
Q: Which connector does it use?
A: It uses an SMA connector and RG141 cable. Confirm the exact SMA gender and interface required for your equipment before ordering.
Q: Can I use it with any FPV drone?
A: Not necessarily. Your radio system must support the 3000–3800 MHz band and compatible circular polarization and RF connections.
Q: Is custom tuning available?
A: Custom frequency tuning may be available. Contact us with your required frequency range and application details.
