isilungekile sokudlulisela 2 Meter: Imiphumela ephezulu ye-VHF yezinhlelo zokuxhumana

Zonke Izigaba

isantena esobukelwe 2 mete

I-antenka yedhisekhi yamaphela ayisithombe esikhulu kakhulu kwalokhu kokuqhubeka kwalokhu kwezinhlelo zokuxhumana, nokuqinisekisa ukuthishwa komsindle kanye nokuthuthukiswa kwezivinini. Le antenka ethunyelwe isebenza kumandla we-VHF, ngokuchazwe yindlela yokusebenza kumandla we-144-148 MHz okusetshenziselwa ngabantu abasebenzisa iradiyo ngokwayo. Isithafo seantenka sengxenye engaphezulu kwezinhlobo eziningi, kanye ne-element evelayo, ukuthwalisi kanye nezidilitha, ezilayishwe ngendlela ethile ukwenza umugqa oqondile. Le nto ikhomba ukuthuthukiswa okukhulu komsindle ngokulingana nezantentenka ezingenakukhathwa, ngezindlela ezingu-7 kuya ku-15 dBi ngokwesimo nezinani lezinhlobo. Iqendu lokusebenza kanye neantenka ikhomba ukuthi kusebenzakala kakhulu kumoya ocisha, ukuxhumana phakathi kwezimo ezahlukene, kanye nokusebenza kwezilwandle. Isithafo seyona antenka sengxenye engapheli kakhulu izinhlobo ezifanelela nezimali ezingapheli kanye nezilicoco ezingenakuthi zihlatshelwa, ukunquma ukuthi kusebenze kakhulu kuzo zonke izimo zomfula. Isithafo seyona antenka senhlobo yokuxhumana nezindlela zokuvikela ukuthi kuhlanganise kanye nokuvikela indawo yokulayisha, okungenzeka ukusebenzisa izinhlobo zika-gamma noma beta ukuthi kusebenze kahle kuzo zonke i-2 meter band.

I-antenna ephindwe 2 imitha inikeza amaphesenti amaningi okwenza yena ngumsebenzisi ongcono ngokweqile kubalulekile kubantu abasebenzisa iradiyo kanye nobasebenzisi beekominikesheni. Okokuqala, izici zokuphindwa kwalo kuvumela ukunikeza okuphezulu kakhulu nokwehla kwe-isikhungo esifanele, okwenza ngokuphindwe amandla wesiqinisekiso samathoni. Lokhu kwenza kunciphisa ukungcola ukusuka kuzindawo engafanele kanye nokuthuthukiswa kweqembu le-sinyelwa kanye lezinyelwe, okwenza ukuthi kulinde isikhungo esibonakalayo. Izici zokuthola amandla zesiqinisekiso zamathoni kuvumela abasebenzisi ukuthi bafinyelele kizinye indawo ngaphansi kwe-amandla, okwenza yena ngumsebenzi ongcono kanye nezimali. Ukubulwa kwalo kuvumela ukusebenza okuphezulu ngokuphezulu emathweni akhulayo, noma kunjalo ukubulwa kwezinhlelo zokubulwa okuvumela ukuthi kwenzeke ukusungwa nokulungiswa ngokomoya. Ukhampele isikhungo kuzindawo engafanele kunciphisa ukungcola emathweni akhona, okungcono kakhulu emakhaya. Kwezinye izimo zokulungiswa, izici zokuthola amandla zesiqinisekiso zamathoni kungcono kakhulu ekutholeni izinkxenye ezifanele. Ukusebenzisa okuphumelelayo kuyindlela ezahlukene, kusuka kubalulekile kubasebenzisa iradiyo kanye nezinhlelo zokulungiswa kanye nezimiso ezinhle.

Ukunqo kwe-isayithi nokuba khona

Isiqhawuli se-2 meter esebenza ngokwesigidi sinquma ngokuthi singasebenzisa amandla we-radiyo kumoto othile, ekwaziwa ukuthola amaphesenti amaningi aqhubekela kakhulu ngokushesha kuzo zokusebenzisa amandla aphelele. Lokhu kusebenza ngokuthi kuhlelwe kahle ukuphakama nokubalwa kwezinqawawa, okwenza ukuthi sibe ne-moto oqotho okaqwa kakhulu engenzelwe ukuthi singasebenzisa isiqinisekiso sakho kakhulu ngokuphindaphindwe kwamathathu amaningi kumoto othile. Isiqhawuli sasolwa ukuthi sineganyo ekuqaleni kanye nezindawo ezingama-7-15 dBi, okwenza ukuthi siphindaphinde amandla wokuthumela kanye nezindawo ezingu-5 kuya ku-30 kumoto ethile. Lokhu kusebenza ngokulandela isiqinisekiso futhi kunciphisa ukuthola kwezinye izigidi, kuvumela ukuthi uthole izigidi ezintile ezidinga ukutholwa ngazo ngokusebenzisa iziqhawuli ezingcono. Isigidi sokugcina kuya kuleyo, okungenani ngu-20 dB, sivumela ukuthi sikhuphe kahle izigidi ezingathanda.

Ukubulwa Okuphezulu Kwamavulekile

Ibukelwe ukuthola imikhomo ephakeme kakhulu yesilwane, i-antenna enkulu ye-2 mete ephathelene nezinhlelo zokubulwa ezinhle futhi zokuthiwa kahle ukuthi yilapho futhi ibone ukusebenza kwayo. Isilwane esincane futhi izinhlobo zayo zinhle zokubulwa kuvumela ukuthi kutholwe ukuphelelwa okuphezulu kakhulu nezimo eziyisisekelo. Zonke izinhlobo zokubulwa, futhi kuzivumelana nezindlela zokubeka futhi izinkinga, zibukelwe ngokubhokisi obucayi ukuthi kungakhali futhi kuthathe ukuphelelwa kwayo ngemva kwezikhathi ezingcono. Indawo ekusetshenziswa ngayo i-antenna iyaphathelene nezindlela zokuvuselela izimo zokulula futhi kuthathe ukuthi kungakhali futhi kuthathe ukusebenza kwayo. Ukubulwa kwesibonelo kuyakhiwa ukuthi kuthole amavulekile okuya kuma-100 mph futhi kuthathe ukusebenza kwayo kanye nezimo zokubulwa.

Ikhwegesithi Zokusebenzela

I-antenna enkulu yamathupha ebonisa ukusebenza okuningi kuzo zonke izimo zokuxhumana, ngakho yindlela enhle yokusebenza kakhulu. Kuzo zokuxhumana ngemini, izici zokuxhumana zayo zivumela ukuthi kutholwe izinko ephumelelayo kuzo zonke izindawo, okudingekile kakhulu ngemizuzwana yokuphila. Kuma-operator abasebenzisa iradiyo, izici zokuthola amandla angaphezulu kanye nezici zokuxhumana ngendlela ethile ayenza kube yindlela enhle kakhulu kuzo zokugcina amaphuzu kanye nezinyathelo zokuxhumana noma kuzo zokugcina izinto ngemali. I-antenna iyisisekelo kakhulu kuzo zokuxhumana ngamaphoyinti amadoda, ivumela ukuthi kutholwe kanye nokuxhumana nawo amaphoyinti amadoda afanayo noma amadoda amakhulu athi ahlukene ngemva kwemva.
