The length of the antenna to be pulled depends on the frequency of the test. It is better to have 1\/4 wave as much as possible. The handheld walkie-talkie is about one meter away from the field strength meter. Don’t be too close! In order to avoid the signal is too strong to burn the field strength meter! Then press the walkie-talkie PTT button to make the walkie-talkie enter the launch state. At this time, the pointer of the field strength meter should have a signal indication. The stronger the signal, the greater the indication!\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp class=\"detail-desc-decorate-title\" style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\"\u003eAmplitude adjustment:\u003c\/p\u003e\n\n\u003cp class=\"detail-desc-decorate-content\" style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\"\u003eIf the field strength indicator indicates that the maximum range is exceeded, the “amplitude adjustment” can be adjusted to let the pointer indicate the appropriate position.\u003cbr\u003e\nMethod for testing the maximum gain point of an antenna\u003cbr\u003e\n1. In order to change the frequency conveniently and quickly, you should use the keyboard to set the frequency walkie-talkie manually.\u003cbr\u003e\n2. Link the walkie-talkie and antenna feeders, place the field strength meter near the antenna (depending on the environment), place it within the vertical radiation angle of the antenna as much as possible, and the antenna planning method is best.\u003cbr\u003e\n3. Set the frequency of the walkie-talkie, press the launch button, observe the meter reading, and register the meter reading. Then set the walkie-talkie to other frequency points, let the walkie-talkie enter the launch state again, observe the meter reading... and then compare the readings of each frequency point! You can know the best frequency\/segment of the antenna under test!\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp class=\"detail-desc-decorate-title\" style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\"\u003ePackage include:\u003c\/p\u003e\n\n\u003cp class=\"detail-desc-decorate-content\" style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\"\u003e1 x Field Strength Indicator Meter\u003cbr\u003e\n1 x Antenna\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\u003cscript\u003ewindow.adminAccountId=206079709;\u003c\/script\u003e","brand":"Cartoolshop","offers":[{"title":"Default Title","offer_id":47412762345639,"sku":null,"price":40.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0080\/7908\/1562\/files\/Sd095e605859c432cbae4443ddaf6c943v.webp?v=1765365209","url":"https:\/\/www.cartoolshop.com\/products\/new-100khz-1000mhz-field-strength-indicator-meter-rf-signal-level-meter-antenna","provider":"Cartoolshop","version":"1.0","type":"link"}
