VHF eriyali kunye izandla zenu; uyilo okuzithandelayo

VHF eriyali - isixhobo nelungiselelwe ukufumana radiation. Ezi nguqu ungakwazi ukusebenza kuphela iimpawu elifutshane. Onobuhle omnye komnye bahluka rhoqo. Uthi ukuze irediyo FM kunye izandla zakho ngokuya phezu imiyalelo. Kulo mzekelo, kubalulekile ukuba siqwalasele uhlobo receiver. Ngaphezulu, kufuneka kuqatshelwe ukuba kukho iintlobo ezahlukileyo eriyali, eziya kwahluka kubume kunye parameters.

Umfuziselo umyalezo olula

Kukho i-eriyali for FM ne izandla zakho rhoqo kwi ukuma nkqo. Ngelo xesha nye ilinganisa kubhetele ukuba kusetyenziswe ubude encinane. Ukulungisa imiqobo iwelding inverter. Ngokuyintloko vuna imasti, nto leyo eya ukugcina inkxaso. ububanzi balo kufuneka ubuncinane 1.2 cm. Kuba yokukhulisa uphawu reception usebenzisa reflectors. Izilungiso ezininzi yokubeka lubekwe engile okungephi.

Isiseko-eriyali kufuneka makwenziwe ephakathi. Ngelo xesha neebhalansi bavunyelwe ukuba ubhale kwi tape. Iingcali zithi ityhubhu sentsimbi bamba kakuhle. Ngokuba uhle kwicala ezigxekayo isicelo kugqame. element kuthethwa zixhonywe ngohlangothi imasti.

Isixhobo nesakhelo

Uthi ukuze irediyo FM kunye izandla zakho kwenziwa kunye ezitsho ezahlukeneyo. Imifuziselo phakathi ixabiso conductivity ezahlukeneyo inzuzo. Xa Wahlanganisa iyunithi kubalulekile ukulungiselela imasti esiqinileyo. Iingcali ukucebisa ukusebenzisa nedawo Wosenza iintsimbi ezincinane. Ubukhulu kufuneka ibe ubuncinane 2.2 cm. Xa siqwalasela imodeli balwamkele ephantsi rhoqo, i counterweights kungaba ukhethe ukusuka insimbi. Akukho mfuneko ukufaka yethemba.

eriyali kugqame bewasebenzisa ezitsho ezahlukeneyo. Emarikeni zokuguqulwa rhoqo ukuya iintyatyambo. Zinelungelo inzuzo eliphezulu. Nakuba kunjalo, kufanele kuqatshelwe ukuba kunzima ukuvelisa ngokwabo. Le zokumisa yangaphambili aqhumisele phezu usebenzisa inverter welding. Kungqameko-eriyali kufuneka sanded ngenyameko. Ntsimbi zilapha phezulu ingasetyenziswa sangqa 0.3 cm. Ukuze ekulweni uphazamiseko livakale ukubetha usebenzisa reflectors ezizodwa conductivity eliphezulu. Onobuhle zokumisa tye zenziwa kunye imasti enye kuphela.

Model nge ntsimbi zilapha phezulu ezimbini

Nge ntsimbi zilapha phezulu ezimbini VHF eriyali kunye izandla zenu ukuya imasti ngokubanzi. Imizekelo lo hlobo zifanelekile ukuba balwamkele ezahlukeneyo series. Ngokuqhelekileyo, ixabiso eliphezulu yeepatheni ukumelana, baye bakwazi ukusebenza kwi ezitsho ngaphezu 300 MHz. izixhobo abaninzi basebenzisa reflectors ezininzi. Ngexesha ibandla le modeli kufuneka kulungiswe imasti engundoqo. Njengomgaqo, iingcali basebenzisa umbhobho omncinci kunye eziphelweni ziloliwe. Kufuneka kuqatshelwe ukuba kukho onobuhle amacebiso. Enanikade counterweights abe elapha engile ezahlukeneyo. Ubude stud kwi-eriyali elula ilingana ukuya kwi-22 cm.

Ukwandisa inzuzo, iityhubhu zentsimbi zisetyenziswa. Kukho kwakhona ukuguqulwa caba. Zisebenza kumaza ka 200 MHz e. Kwicala senzo kwi-eriyali ungahluka. Inxalenye esezantsi isixhobo nedawo ekwanti. Le kugqame kufuneka ilungiswe kakuhle. Le counterweight ukuze mayixhonywe ngokuxwesileyo.

Kufuneka kuqatshelwe ukuba ukuze koyiswe ingxolo isigaba kufuneka asebenzise reflectors evuthelweyo. Imasti ukumelana imithwalo eliphezulu. Eriyali yale hlobo ezilungileyo kakhulu polarizations ezimbi. Noko ke, kule meko kuyimfuneko ukuze bakuthathele ingqalelo uhlobo umamkeli kunye umda rhoqo.

antenna oxwesileyo

eriyali Tye kungenziwa ndawonye kunye counterweights iimilo ezahlukeneyo. Izilungiso Simple zenziwa migca iimasti. Kukho kwakhona ezininzi izixhobo ophezulu rhoqo, nto leyo enziwa kunye kugqame yomgama, nto leyo elapha ezantsi yokubeka. eriyali Tye kufuneka nje ubenesahlulo eliphezulu amanzi. Bayakwazi ukusebenza kumaza ka 200 MHz e.

imifuziselo ezininzi baxhotyiswa counterweights kabini. Kulo mzekelo lwemasti esisetyenziswa 1.2 cm ububanzi. Abanye alungele ukusetyenziswa kunye balwamkele ekhaya. Bona inomlingani eziphezulu emi otshangatshangiswayo. Ntsimbi zilapha phezulu ivame kwindawo esinekona sasekunene. Counterweights nje phambi kwefowuni.

ukuguqulwa nkqo

eriyali nkqo bekwazi ukusebenza kwi ezitsho ezahlukeneyo. Uguqulo yale hlobo abe yokukhulisa factor eliphezulu. It is a VHF eriyali nkqo ilula ukuze irediyo ngezandla zakhe. Okokuqala kufuneka ukuba ukukhetha bar elungileyo, ukulungiselela kusengaphambili iwelding inverter. Ukusombulula iingxaki nokwehlukana ezigxekayo Kucetyiswa ukuba basebenzise reflectors ukubetha. Ngelo xesha balances kufuneka ufake i ubude enkulu apha kufuneka bungabi ngaphantsi kwe-0.3 cm. Ukuze kuphuculwe ugqaliselo isihluzo iyasetyenziswa. Kwidesika ekufuneka sifakwe kuphela kwi-engile degrees 45. Nangona kunjalo, kubalulekile ukuba pre-ukubala amandla useko lwemasti.

Ukwandisa uzinzo isakhiwo esisiseko luzakwenziwa abutments. Yeyona eriyali FM ukuze irediyo ngezandla zabo kuphela kunye namaqhosha ezimfutshane ekufuneka ifakwe kwi kubude elisezantsi. Counterweights ukuba bakope kwi bar. Kufuneka banyamekele linings. ingqalelo eyodwa inikwa uphando kwicala, ezo zigxunyekwe imasti. Ukwandisa kwindawo ukuchithachitheka yokubeka ekucetyiswa-25 ubude cm.

Izixhobo 144 MHz

VHF antenna at 144 MHz ngezandla zabo i ngqo okanye ukugoba bar. Useko lwemasti kulo meko isicelo kunye abutments elibhalwe ngokumileyo. Kwezinye iimeko, wasebenzisa reflectors idaleka. Yeyona eriyali UHF 144 ngezandla zakhe kwezibonda ecaleni. Ubude ngokupheleleyo isekela ilingana no-15 cm. Abanini ngaphambili zisetyenziselwa ukwandisa inzuzo. Ngenxa umthetho, ukuba ziyaxhonywa ngezibopho. VHF antenna at 144 MHz izandla zakho kwenziwa omnye okanye emibini zokumisa.

Ukuguqulwa at 145 MHz

VHF antenna 145 MHz ngezandla zabo wenza imasti elifutshane. Eyona iinguqulelo ezininzi eziqhelekileyo zithathwa iintsika ezintathu. inzuzo onobuhle kakhulu eliphezulu. Iimbaleki evela eriyali ezisetyenziswa kunye reflectors ukubetha. Ebizwa yangaphambili kusetwa kuphela ngokusebenzisa inverter welding. Xa imizekelo directivity ophezulu. Iingcali zithi-eriyali uvumelekile ukwenza imasti egosogoso.

Model ne andizele zobhedu

Kukho i-eriyali ukuba band UHF ngezandla zabo kunye reflectors ezitsho ezahlukeneyo. Pillars ekufuneka sifakwe okanye ngaphandle iirholithi. Ezinye iinguqulelo Senziwe amanqwanqwa ecaleni. Eriyali bokwenziwa nokuphalazeka kwelifu high ingumlingani. Okokuqala imvelaphi inyuselwa imasti. Counterweights nga mayixhonywe kwindawo engile okungephi.

Le ezikhaphukhaphu enobubanzi elilelona ngu 1.2 cm. Kulo mzekelo lwemasti kuyacetyiswa ukuba kusetyenziswe kwisiseko esiluqilima. Ukuba sithethe malunga kugqame, kuyimfuneko ukuba usebenzise ukubetha okanye uhlobo wire. Ukuze wenze imodeli elula kusetyenziswa counterweights ezine. Zokubhala soldered usebenzisa inverter welding. Ngaphezu koko, ukuba icebo ngezandla zenu, ekhwele ulwahlulo phantsi imasti. indawo ukusasaza Gain kunokufikelelwa ngokusebenzisa ezikhaphukhaphu osecaleni.

Devices ne andizele intsimbi

On imasti sentsimbi VHF eriyali yenziweyo ngezandla zabo kunye elibhalwe ngokumileyo retinaculum. Counterweights ifakiwe, ngokuqhelekileyo kwicala elinye. Ezinye iingcali bacebisa ukusetyenziswa zikhondo enobubanzi ka-2.2 cm. Ukuze kuphuculwe ugqaliselo ifowuni isicelo ukubetha kugqame, nto leyo imvelaphi inyuselwa khona emazantsi-eriyali. To connect imifuziselo kusetyenziswa ucingo ukusuka imasti. Kananjalo kubalulekile ukuba siqaphele ukuba kukho izixhobo kunye isithinzi icala. Zinelungelo conductivity eliphezulu.

Devices for balwamkele Uvakalelo oluphantsi

Receiver uvakalelo for eliphantsi eriyali VHF ngokuya kakhulu elula izandla zakho. Inyathelo lokuqala sivunwa lwemasti, nto leyo zinxibelelene nenqwelo ecaleni. Counterweights idla ngokusetyenziswa kunye guides elibhalwe ngokumileyo. Umdlalo iqinile kwisiseko esiluqilima. Xa imifuziselo olu hlobo kufuneka zisetyenziswe kugqame kwentambo. Counterweights ukuze efakiweyo ngokuxwesileyo. Kuba yokukhulisa inzuzo uvumelekile ukunyusa bahambahamba ubukhulu elide 2.2 cm.

Iimfaniso ukuba balwamkele uvakalelo oluphezulu

Kuba balwamkele data VHF eriyali ye-430 MHz izandla oko kwenziwa imasti ngensimbi. Ezinye iingcali Sazisa ngamandla ukusetyenziswa kuphela nesakhelo egosogoso. Kulo mzekelo, i counterweights kufuneka busisigxina kwisakhelo kwisiseko. EziQhelekileyo VHF eriyali kunye izandla zakho kwenziwa oluneentlobo ezahlukeneyo reflectors.

Qala kancincane indibano kufanelekile ukuqinisekisa lwemasti nokuchithela iingcingo ukudibanisa. Ngaphezu koko, ukuba icebo ngezandla zakho kufuneka ukugawula izibonda amane ububanzi of 2.2 cm. Le modeli kwi MHz 200 kufuneka babe nezinye izinto ezintathu icala. Counterweights ekufuneka sifakwe kwi-engile degrees 45. Pillars zifakwe kwi emazantsi imasti.
