Amakuru - Helical Duplexer yo gutumanaho ya VHF/UHF

Imirongo ya VHF/UHF ikomeje kugira uruhare rudasimburwa mu itumanaho rya gisivili n’iry’inganda.icyuma gikingira imirasireifite ubushobozi bwo kuyungurura neza, iramba cyane kandi ihendutse, bigatuma iba amahitamo meza kuri sisitemu za radiyo, repeaters na telefoni zigendanwa.

Akamaro k'ingenzi k'ibiicyuma gikurura imirasire kigendanwa gikozwe mu buryo bwa helicalishingiye ku miterere yayo y'insinga, ifatanye n'uburebure bwose¼ λikoranabuhanga rya resonance. Iyi miterere yemerera gutunganya muri Frequency ya 150MHz na 380-450MHz iri hagati yayo mu gihe igera kuri dB zirenga 85 zo kwitandukanya—bigafasha mu gusesengura neza ibintu bidafite ingufu za elegitoroniki no kugabanya igihombo cyo kwinjira ku rugero runini. Mu buryo bw'imiterere,icyuma gikingira imirasireIfite agasanduku gato ka aluminiyumu gakozwe muri aluminiyumu, kandi karimo icyuma gikozwe mu cyuma gishyushye n'ibikoresho bya Teflon bitwikiriwe n'ubushyuhe. Inyuma yayo hatwikiriwe na vinyl y'umukara idakonjeshwa n'ingese, bigatuma ikora neza ndetse no mu bidukikije bikomeye byo hanze no mu nganda.

⭐Ibintu bitatu by'ingenzi bikoreshwa

1. Ibikoresho bisubiramo imbaraga nke: Igumana igipimo cy’umuvuduko muke uhoraho (VSWR) mu gihe cy’igihe kirekire cyo gukora imizigo yuzuye, bigabanya cyane igihombo cy’ingufu. By’umwihariko ikoreshwa mu bice by’imisozi miremire, munsi y’ubutaka, n’ahandi, ifasha kwagura uburyo bwo gutumanaho.

2. Radiyo zikoresha insinga za digitale na analog: Ikora ku miyoboro ya VHF 150 MHz na UHF 380–450 MHz, ituma habaho guhuza neza n'ibikoresho bisanzwe bitabaye ngombwa ko habaho izindi frequency. Ikuraho burundu uburyo bwo kuvugana mu buryo bugoye mu bidukikije by'amashanyarazi, ikanafasha mu itumanaho ry'umwuga ndetse no mu gukoresha radiyo y'abatarabigize umwuga.

3. Telefoni yuzuye Ibikoresho bya Duplex: Ifite imiterere mito, irwanya guhindagura, kandi ikanahindura ubushyuhe, ituma uburyo bwo kohereza ibimenyetso bugenda neza kandi buhurirana. Ni igice cyiza cyo guhuza ibintu nko gutabara mu buryo bwihutirwa no mu bikorwa byo mu kibuga.

Ugereranyije n'ubunini bwa duplexer isanzwe, iki gicuruzwa gifite uburinganire busesuye hagati y'imikorere n'imikorere, gifite inyungu zikomeye mu gukoresha ingufu neza no kugabanya ikiguzi. Kirakwiriye gukoreshwa mu mishinga minini no kuvugurura ibikoresho by'umwuga, gitanga inkunga ikomeye ku itumanaho rya VHF/UHF ry'igihe kizaza..

Twandikire kugira ngo ubone ibiciro! Iki gicuruzwa gikoreshwa cyane mu mutekano rusange, mu gutwara abantu n'ibintu, mu buryo bwikora mu nganda, no mu maradiyo y'abatarabigize umwuga, cyizewe cyane n'isoko.
