Moksona antenu ieviesa in\u017eenieris un radio entuziasts Les Moxon no Anglijas. T\u0101s unikalit\u0101te sl\u0113pjas t\u0101s vienk\u0101r\u0161aj\u0101 dizain\u0101 un augst\u0101 veiktsp\u0113j\u0101. Moksons ierosin\u0101ja antenu ar diviem elementiem, kuras izm\u0113rs lieces d\u0113\u013c tika samazin\u0101ts par 25 %. Viena no t\u0101s galvenaj\u0101m priek\u0161roc\u012bb\u0101m ir t\u0101s 50 omu pretest\u012bba, kas \u013cauj to tie\u0161i savienot ar kabeli bez papildu komponentiem. <\/p>\n\n

K\u0101 darbojas antena?<\/h3>\n\n

Moksona antena sast\u0101v no div\u0101m da\u013c\u0101m: direktora<\/strong> (izstarojo\u0161\u0101 da\u013ca, kas virza sign\u0101lu) un reflektora<\/strong> (atstarojo\u0161\u0101 da\u013ca, kas pastiprina sign\u0101lu v\u0113lamaj\u0101 virzien\u0101). Svar\u012bgi atz\u012bm\u0113t, ka antenas polariz\u0101cija ir line\u0101ra. Ja antena ir novietota horizont\u0101li, ar\u012b polariz\u0101cija b\u016bs horizont\u0101la. Tas ir \u013coti svar\u012bgi FPV sist\u0113m\u0101s, kur polariz\u0101ciju saska\u0146o\u0161ana var iev\u0113rojami uzlabot sign\u0101la kvalit\u0101ti. <\/p>\n\n

Moksona antenas priek\u0161roc\u012bbas<\/h3>\n\n
    \n
  1. Pla\u0161s frekven\u010du diapazons<\/strong>. Antena var darboties pla\u0161\u0101 frekven\u010du diapazon\u0101, padarot to par daudzpus\u012bgu risin\u0101jumu da\u017e\u0101d\u0101m radio sist\u0113m\u0101m. <\/li>\n\n\n\n
  2. Tie\u0161ais kabe\u013ca savienojums<\/strong>. Pateicoties 50 \u03a9 pretest\u012bbai, antenu var viegli savienot ar raid\u012bt\u0101ju vai uztv\u0113r\u0113ju, t\u0101d\u0113j\u0101di vienk\u0101r\u0161ojot t\u0101s uzst\u0101d\u012b\u0161anu. <\/li>\n\n\n\n
  3. Sign\u0101la pastiprin\u0101\u0161ana<\/strong>. Lai gan Moxon antena nepied\u0101v\u0101 lielu pastiprin\u0101jumu (aptuveni 5-7 dBi), t\u0101 tom\u0113r dubulto sign\u0101la stiprumu, kas ir \u013coti svar\u012bgi viet\u0101s ar v\u0101ju radio p\u0101rkl\u0101jumu. <\/li>\n\n\n\n
  4. Viegli uzb\u016bv\u0113jams<\/strong>. Antenu var viegli izgatavot pat m\u0101j\u0101s. Augstfrekven\u010du lietojumiem to var iegrav\u0113t uz PCB, t\u0101p\u0113c t\u0101 ir ide\u0101li piem\u0113rota DIY projektiem. <\/li>\n\n\n\n
  5. Vienk\u0101r\u0161i apr\u0113\u0137ini<\/strong>. Moksona antenas konstrukciju ir viegli apr\u0113\u0137in\u0101t, izmantojot vienk\u0101r\u0161us antenu kalkulatorus, t\u0101p\u0113c t\u0101 ir pieejama gan amatieriem, gan profesion\u0101\u013ciem. <\/li>\n<\/ol>\n\n

    Pielietojums FPV<\/h3>\n\n

    Moxon antena ir atradusi savu vietu FPV sist\u0113m\u0101s, pateicoties t\u0101s kompaktajam izm\u0113ram un virziena sp\u0113j\u0101m. T\u0101 pal\u012bdz uzlabot sazi\u0146as kvalit\u0101ti un kontroli drona darb\u012bbas zon\u0101. \u0160\u012b antena ir \u012bpa\u0161i noder\u012bga lidojumiem lielos att\u0101lumos, kad nepiecie\u0161ams sign\u0101la pastiprin\u0101jums noteikt\u0101 virzien\u0101. <\/p>\n\n

    K\u0101d\u0113\u013c atkal ir aktu\u0101la Moksona antena?<\/h3>\n\n

    P\u0113d\u0113jos gados Moksona antena atkal ir izpeln\u012bjusies radio entuziastu un ekspertu uzman\u012bbu, jo to var viegli piel\u0101got jaun\u0101m frekven\u010du josl\u0101m. Piem\u0113ram, daudzi tagad to p\u0101rveido t\u0101, lai t\u0101 darbotos ELRS<\/strong> (ExpressLRS) frekven\u010du diapazonos, kas ir \u012bpa\u0161i svar\u012bgi FPV sist\u0113m\u0101m, kur katra sign\u0101la aizkav\u0113\u0161an\u0101s sekund\u0113 var ietekm\u0113t drona vad\u012bbu. Ar\u012b m\u016bsu pretinieki ir s\u0101ku\u0161i masveid\u0101 p\u0101rveidot \u0161o antenu zem\u0101ku frekven\u010du diapazoniem, padarot to par b\u016btisku instrumentu m\u016bsdienu konfliktos. <\/p>\n\n

    Moxon antena ir lielisks piem\u0113rs tam, k\u0101 vienk\u0101r\u0161\u012bba un efektivit\u0101te darbojas roku rok\u0101. T\u0101s priek\u0161roc\u012bbas padara to par ide\u0101lu izv\u0113li tiem, kas v\u0113las uzlabot sava drona komunik\u0101ciju, neiedzi\u013cinoties sare\u017e\u0123\u012btos in\u017eeniertehniskajos risin\u0101jumos. T\u0101s vienk\u0101r\u0161\u0101 konstrukcija, uzticam\u012bba un piel\u0101go\u0161an\u0101s sp\u0113jas jaun\u0101m frekvenc\u0113m padara \u0161o antenu par lielisku izv\u0113li modern\u0101m FPV sist\u0113m\u0101m. <\/p>\n","protected":false},"excerpt":{"rendered":"
