Note:
1. It is not for use on the 2meter band,CB band or wifi.
2. Never mount a vertically polarized yagi in the middle of the boom on a metal mast.
3. When receiving, when the vibrator is perpendicular to the ground, it is conducive to long-distance communication. If the vibrator is parallel to the ground, it will affect the gain and form an Angle with the ground, which is not conducive to long-distance communication.
4. The Yagi antenna is no need operates for a grounding in most cases. But you can ground antenna via the outer conductor of the connector and the cable, or through the mounting hardware, you can install a lightning surge protector between the Yagi and a device to prevent a lightning strike to the antenna from damaging your device and equipment.
Yagi antenna is composed of an active vibrator, a reflector and a number of director.A reflector longer than the active vibrator reflects energy.The director, which is shorter than the active vibrator,directs the energy.The reflectors and director on both sides of the active vibrator change the original bidirectional radiation into unidirectional radiation to improve gain of the antenna.Yagi antenna has a simple structure, high gain,is widely used in UHF/VHF frequency band.(5 Elements yagi is only work for UHF frequency) VHF Yagi: B08PSKNMDF
Questions 1: Is the SWR of the antenna to be less than 1.5?
Answer 1:
Antennas are rigorously tested by a comprehensive measuring instrument before the delivery, the SWR conforms to the technical parameters provided by the manufacturer (less than 1.5) within the frequency range of the antenna.But the test results of SWR are affected by many factors, such as test frequency, antenna installation mode and installation position, feeder line, test instrument and so on.Generally speaking, antennas can be used normally when SWR under 2.0.If your antenna's swr is too high,we will be happy to analyze and solve for you.
Questions 2: Is the antenna suitable for indoor or outdoor use?
Answer 2: It can be used both indoors and outdoors.It depends on what you use it for.
