Nigute ushobora gukora antenne ya Kharchenko kuri TV ya digitale ukoresheje amaboko yawe: kubara, guteranya biquadrate

Noneho hari impinduka zifatika za tereviziyo igereranya yerekana kuri digitale. Kuva mu mwaka wa 2012, hashyizweho urwego rumwe kuri tereviziyo ya televiziyo ya DVB-T2 kugira ngo rurebe ku buntu. Kugirango ubone amahirwe nkaya, hasigaye gusa kubona resept-antenna, ushobora gukora wenyine. Bumwe mu buryo buhendutse kuri TV ya digitale ushobora guterana n’amaboko yawe ni antenne ya Kharchenko.

Ibiranga nibikoresho bya antenne ya Kharchenko

Igitekerezo cyo kwikorera ibikoresho gishingiye ku iterambere rya injeniyeri Kharchenko. Antenna yakoraga murwego rwa decimeter (DCV), izwi cyane mumpera z’ikinyejana gishize. Iyi ni analogue ya antenne aperture ishingiye kubiryo bya zigzag. Ikimenyetso cyegeranijwe hifashishijwe icyerekezo kiringaniye (ecran ikomeye cyangwa lattice – ikadiri ikozwe mubikoresho bitwara ibintu), byibuze byibuze 20% kuruta vibrateri. Kwikorera wenyine, bizaba ngombwa kuzirikana imiterere ya geometrike no guhitamo ibikoresho runaka.
Ikimenyetso cya tereviziyo gitangwa hifashishijwe imiraba hamwe na horizontal polarisation. Imiterere yoroshye ya antenne itangwa muburyo bwa horizontal ebyiri zuzunguruka zuzuzanya zifitanye isano, ariko zaciwe aho ibiryo (umugozi) bihurira. Ibipimo byagaragaye mu kiganiro cya Kharchenko “Antenna yo mu rwego rwa DTSV”, kandi antenne ibarwa ukurikije formulaire yatanzwe n’umwanditsi.

Turakora imibare

Kugirango hakorwe antenne ya Kharchenko, birakenewe gukora ibarwa nyayo ukoresheje calculatrice cyangwa formulaire. Ukoresheje ubwo buhanga, urashobora kubara iyinjizwa rya antenne nubwo ufite ibimenyetso bidakomeye – hafi 500 MHz. Ubwa mbere ugomba kumenya inshuro zibiri za DVB-T2 za TV zamamaza mukarere kawe. Ibi murashobora kubisanga kurubuga rwa interineti rwa CETV. Ngaho ukeneye kubona umunara wa TV wegereye, kimwe no gutangaza amakuru (imwe cyangwa ebyiri zipakurura umuyoboro) hamwe ninshuro zikoreshwa muribi. Nyuma yo kumenya indangagaciro zinshyi zipaki, uburebure bwimpande zumwanya wa antenne-yakira yabariwe. Igishushanyo nigishushanyo cya antene byakusanyijwe hashingiwe ku kimenyetso cyo kohereza ibimenyetso. Hertz (Hz) ikoreshwa mu kuyipima kandi igaragazwa n’inyuguti ya F. Nkurugero, urashobora gukoresha inshuro nyinshi kuri tereviziyo yerekana udupaki twa mbere nuwa kabiri mu mujyi wa Moscou – 546 na 498 megahertz (MHz).

Kubara

Kubara bikorwa ukurikije formula: umuvuduko wurumuri / inshuro, nibyo: C / F \ u003d 300/546 \ u003d 0.55 m \ u003d 550 mm. Muri ubwo buryo bwa kabiri multiplex: 300/498 = 0,6 = 600 mm. Ibipimo by’uburebure ni 5, 5, na 6 dm. Kubakira, ukeneye antenne ya UHF, yitwa antenna ya decimeter. Nyuma yibyo, biroroshye cyane kubara ubugari bwumuraba hejuru, biteganijwe kubakira. Ni 1/2 cy’uburebure, 275 na 300 mm kuri paki ya mbere n’iya kabiri.

Kugirango ubashe kwakira neza ibimenyetso bya digitale, buri mpande zombi zigomba kuba igice cyubugari bwumuraba wa diameter. Mu gukora, nibyiza gukoresha intoki ya aluminium cyangwa umuyoboro wumuringa. Byiza, nibyiza gukoresha insinga z’umuringa (3-5 mm) – ifite geometrie ihamye kandi yunamye neza.
