Preguntas Frecuentes (FAQ)
Q: What type of UFL/IPEX connector does the HGLRC mini Hammer antenna use and how can I check whether it is compatible with my VTX or receiver?
A: The HGLRC mini Hammer antenna uses a UFL/IPEX connector, also known as IPEX MHF4. To check compatibility, you must make sure your Video Transmitter (VTX) or FPV receiver also has a UFL/IPEX connector. This connector is very small and delicate, so carefully check your equipment's specifications or consult the manual to confirm the connector type.
Q: The description lists a VSWR of ≤1.5 at 5800MHz. What does this value mean and how does it affect my FPV system's performance?
A: VSWR (Voltage Standing Wave Ratio) is a measure of the efficiency of energy transfer between the transmitter (VTX) and the antenna. A low VSWR indicates good impedance matching and therefore more efficient energy transfer. A value of ≤1.5 is generally acceptable for FPV, but the lower the better. A high VSWR can cause signal loss, interference and, in extreme cases, damage the VTX. The mini Hammer, with a VSWR of ≤1.5, should provide good performance on the 5.8GHz band.
Q: What is the difference between RHCP and LHCP polarizations and how should I choose the right one for my FPV system? Is it important that my drone's antenna and my receiver's antenna have the same polarization?
A: RHCP (Right Hand Circular Polarization) and LHCP (Left Hand Circular Polarization) refer to the direction of rotation of the electromagnetic wave. It is crucial that your drone's antenna (VTX) and your FPV receiver's antenna have the *same* polarization for optimal signal reception. If you use RHCP on the drone, you must use RHCP on the receiver, and vice versa. The mini Hammer is RHCP. Using different polarizations will result in significant signal loss and reduced flight range.
