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. \u003cbr\u003e \u003cbr\u003e 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. \u003cbr\u003e \u003cbr\u003e \u003cb\u003eQuestions 1: \u003c\/b\u003eIs the SWR of the antenna to be less than 1.5? \u003cbr\u003e \u003cbr\u003e \u003cb\u003eAnswer 1: \u003c\/b\u003e\u003cbr\u003e \u003cbr\u003e 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. \u003cbr\u003e \u003cbr\u003e \u003cb\u003eQuestions 2: \u003c\/b\u003eIs the antenna suitable for indoor or outdoor use? \u003cbr\u003e \u003cbr\u003e \u003cb\u003eAnswer 2:\u003c\/b\u003e It can be used both indoors and outdoors.It depends on what you use it for. \u003cbr\u003e \u003cbr\u003e \u003cb\u003ePacking inlcudes:\u003c\/b\u003e \u003cbr\u003e \u003cbr\u003e 1*Yagi antenna\u003cbr\u003e \u003cbr\u003e 1*U-Bracket\u003cbr\u003e \u003cbr\u003e 1*Instruction(Not includes the radio and the cable)\u003cbr\u003e \u003cbr\u003e \u003cb\u003eUAYESOK Store:\u003c\/b\u003e If you have any questions about the product, we'll be happy to serve you,We will reply to you within 24 hours. \u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":47423172509884,"sku":"P353529031129436323","price":17.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/3418\/6940\/files\/42598c4aa3fcd1f43cd7bddbece166874a90cead07f309cfa2f48027336f6054.jpg?v=1788749350","url":"https:\/\/www.sweaterclothes.shop\/products\/dual-band-outdoor-yagi-antenna-2meter-70cm-vhf-uhf-9-5-11-5dbi-directional-yagi-8-elements-3-sections-for-amateur-2-way-radio-repeater-system-433mhz-device-police-scanner_a596bca3","provider":"My Store","version":"1.0","type":"link"}
