Product Description

Dual Band Yagi directional antenna

Yagi Antenna Widely used in various directional divice:For Baofeng Motorola Yaesu Kenwood amateur 2 Way Radio;GMRS Repeater Systems;police scanner;433mhz radio system;data radio;satellite work,ISS (international Space Station)contact;Digital Radio.

Aluminium Alloy Material

Lightweight,High strength,Waterproof,Corrosion resistant;good environmental adaptability.

Easy to carry and install

The body of the Yagi Antenna makes it highly resilient to outdoor use. Strong wind resistance,Rated wind velocity 60 m/s.The antenna can be securely attached to the mounting surface with the U-Bracket.

SL-16 FEMALE(UHF FEMALE) Connector

SL-16 FEMALE Connector is the same as SO239 Connector,The elongated design of the interface meet more installation requirements.

High gain benefit(9.5dBi/11.5dBi)

Excellent receive and transmit,extend the Range of Your Communication.(In general, the more elements, the better the effect.)

Note:

1. It is not for use on the 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.

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. 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,SWR may not less than 1.5 under your test environment. Generally speaking, antennas can be used normally when SWR under 2.0. Normally, a calibration kit is required to accurately test the SWR of the antenna itself. 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.
