Nezve antenna yeTV munhu wese anojaira, rangarira yakare nhema nechena TV, ndiyo antenna yayo uye yobva yagadziridzwa kune yekunze danda TV antenna.Asi kusvika zvino, tekinoroji yeTV antenna uye yakawedzera kukura, ikozvino antenna inogona kuzadzisa zvatinoda muhupenyu, shamwari dzakawanda mumusika kutenga antenna, kumusha hazvizoiti kugadzwa kwesainzi.Handizive kuti antenna inoshanda sei, handizive pekuiisa.Nhasi, ini ndichakuzivisa iwe kuisirwa kweTV antenna kuti uite tsananguro yakadzama, ndinovimba kukubatsira.
1. Kushanda musimboti uye basa re antenna
Sechikamu chakakosha chekutaurirana pasina waya, basa rekutanga reantenna kupenya nekugamuchira mafungu eredhiyo.Kana uchitumira, iyo yakakwira-frequency ikozvino inoshandurwa kuita electromagnetic wave;Paunenge uchigamuchira, iyo yemagetsi shock wave inoshandurwa kuita yakakwira frequency ikozvino.
Chechipiri, antenna mhando
Kune akasiyana-siyana maantenna, uye anogona kupatsanurwa muzvikamu zvinotevera: base station Antennas uye mobile portable antennas inogona kukamurwa kuita Ultra-refu wave, refu wave, medium wave, short wave, Ultra-short wave, uye Microwave. Antennas ekushandisa kwavo;Maererano nekutungamira kwayo, inogona kupatsanurwaintoomnidirectional uye inotungamira antennas.
Tatu, nzira yekusarudza antenna
Antenna chikamu chakakosha chehurongwa hwekutaurirana, kuita kwayo kunobata zvakananga index yehurongwa hwekutaurirana, vashandisi vanofanirwa kutarisisa kuita kwayo pakusarudza antenna.Kunyanya, pane maviri maficha, yekutanga sarudzo antenna mhando;Kuita kwemagetsi kwechipiri sarudzo antenna.Kukosha kwekusarudza rudzi rweantenna ndeichi: kana iyo yekumisikidza yeantenna yakasarudzwa inoenderana nezvinodiwa zveredhiyo wave kufukidzwa muhurongwa hwekugadzira;Zvinodiwa pakusarudza mashandiro emagetsi eantenna ndeaya anotevera: Sarudza kana iwo magetsi eiyo antenna, senge frequency bandwidth, kuwana, uye yakayerwa simba, inosangana nezvinodiwa dhizaini yehurongwa.Naizvozvo, mushandisi aive nani kubata mugadziri pakusarudza antenna.
Chechina, antenna kuwana
Kuwana ndeimwe yemaindex makuru e antenna.Icho chigadzirwa chekutungamira coefficient uye kugona, uye iko kutaura kweradiation kana yakagamuchirwa saizi yemafungu eantenna.Sarudzo yekukura saizi inoenderana nezvinodiwa zveiyo system dhizaini yeredhiyo wave yekuvhara nzvimbo.Zvichitaurwa zviri nyore, pasi pemamiriro mamwe chetewo, iyo inowedzera pfuma, kureba kwechinhambwe chekuparadzira redhiyo wave.Kazhinji, antenna ye base station inotora antenna yakakwira, uye antenna yenharembozha inotora iyo yakaderera-inowana antenna.
