Log-periodic eriyali: ukubala zobukhulu kunye neempawu ezisisiseko

eriyali Log-ngamaxesha zihlelwa njengeeyunithi zemiyalelo. Iimfaniso bakholisa ukuba lusebenzise yamaza elifutshane. izixhobo ezininzi baxhotyiswa kugqame vysokoprovodimym. Ezinye iinguqulelo zenziwa vibrator panel. Baye yokukhulisa omnye okanye ngaphezulu. Kufuneka kuqatshelwe ukuba kukho izixhobo kunye samaza ijelo.

Zeziphi parameters eziphambili uhlobo eriyali log-ngamaxesha athile? Okokuqala kubalulekile ukuba uthathe ingqalelo rhoqo ifowuni. Kwakhona ingqalelo ziingcali directivity kunye inzuzo. Igalelo ukuvimba ikwachaphazela parameters eriyali.

models yokubala

Calculation antenna ibuya esekelwe ubude bahambahamba. Xa siqwalasela umfuziselo kunye vibrator, ukuba kugqame kusetyenziswa uhlobo dipole. Ekubeni ubude-20 cm, ububanzi yolawulo kufuneka-30 cm. Ngokwandisa ubungakanani nesakhelo, indawo yolawulo ekhethiweyo ineenkalo ahambelanayo.

Icebo ngezandla zakho

A log-ngamaxesha eriyali ngezandla zakhe isongiwe nge kugqame elula, kwaye vibrator ingcono ukusebenzisa ne ingumsipha ulwandiso. Okokuqala ibekwe imasti ngqo. Ntsimbi zilapha phezulu iyalungiswa usebenzisa umatshini welding. Iingcali ukucebisa ukufaka kwangoko lo mshini.

Iingcingo zombane kufuneka isetyenziswe emhlabeni kuphela. wegazi yeentlobo ezahlukeneyo asetyenziswa ukunciphisa rhoqo. Imifanekiso anikwe amandla ezi ezisebenza ngokubakho contact. Nedawo eliphezulu kuyimfuneko ukuba asebenzise omncinci. Kuyimfuneko ukuba banikele ingqalelo zombini ephantsi, nto leyo iyemka kwicingo. Kuxhomekeka imodeli ukubala kubungakanani log-ngamaxesha eriyali.

Umfuziselo umyalezo olula

iimasti antenna Log-ngamaxesha athile zenziwa babengabafo ephantsi balwamkele ezilula. Eyona iinguqulelo ezininzi eziqhelekileyo zithathwa ukuba abe phezu nezinye izinto ezintathu. Ukuba sicinga eriyali kunye iadaptha omnye, lo kugqame lusetyenziswa capacitor. Kufuneka kuqatshelwe ukuba lwemasti busisigxina ukuya yokubeka. Dumani kule meko kunqabile kakhulu. Amaqhoshana babe eriyali enyusiweyo ngenxa kwizibiyeli. Iingcali zithi imifuziselo ithandwayo ingqalelo kunye ezisebenza ngokubakho dipole. Banakho usebenze iliza elifutshane.

Isixhobo nesakhelo

Uthi ukwamkelwa audio awabelwa a conductivity eliphezulu. Kwimarike kukho izixhobo kunye imishini umva. Ayesebenzisa inkxaso ebanzi ngokufanelekileyo. Ngelo xesha abanini waseka ububanzi encinane. Xa siqwalasela uhlobo log-ngamaxesha athile esezantsi eriyali, ukuba sele kugqame enye. Yokubeka zixhonywe yokuma obandayo. eriyali badla ezithengiswa ngaphandle abanini. yokubeka bawanikiwe kwisiseko ngokubanzi. Umgangatho uphezulu ithathwa ukuba izixhobo kunye ezisebenza ngokubakho eliphezulu. Imishini nazo efakwe ngaphandle i-adaptha. Imele kulo mzekelo, kukho ubude encinane.

Model nge ntsimbi zilapha phezulu ezimbini

UHF log-ngamaxesha eriyali kunye iiyure ezimbini ezenziwe kunye kugqame kwi imiphantsi ezintathu. Iingcali zithi ukuba beye conductivity ezahlukeneyo. Xa ukhetha ulungiso kufuneka ahlawule ingqalelo ukuguqulwa ngenkxaso. Abanini ndiwamise L-ezimise. Lidla olu hlobo eriyali efakiweyo phezu kwendlu.

Izixhobo ezifanelekileyo kokwenza ubuciko umabonwakude. Noko ke, abakwazi ukuba isebenze kuzo zonke ezitsho. Kulo mzekelo, oku kuxhomekeke ukuma kugqame. Iinguqulelo Modern sohlobo eriyali logoperiodic zisetyenziswa kunye yokukhulisa kwimveliso. Phantsi kuzo zichazwe amaqhoshana ezivulekileyo kuphela. Kulo mzekelo, imishini ziyaxhonywa embindini yokubeka. Mast bahluka ubude. Apha kakhulu kuxhomekeke ububanzi yokubeka. Conductivity kuxhomekeke nenguqulo kugqame. Wire antenna angemki le olwandisa.

antenna oxwesileyo

enothi oxwesileyo for uhlobo TV logoperiodic limi kubonise ngokubanzi. imifuziselo abaninzi basebenzisa imasti elide kunye nenkxaso kuphela eyenziwe aluminium ingxubevange. Ukuba oyifunayo, uhlobo eriyali log-ngamaxesha kungenziwa ngokuzimeleyo. Ke inayo kakuhle yomfumani amandla enkulu. Iingcali zithi ukuba umnini lokuqala ibekwa. ke kuphela ungabeka imasti. Inyathelo olandelayo ubeke kugqame. Xa siqwalasela webiwa yokuphila, kuba imishini ezimbini.

Imifanekiso zenziwe ngaphandle zokumisa. Ntsimbi zilapha phezulu ukuba ngokuxwesileyo. Ukuseta uhlobo eriyali log-ngamaxesha kusetyenziswa izinto ebanzi eqwalasele ngentsimbi. Kufuneka kuqatshelwe ukuba kukho loguqulelo aqhelelkileyo apho lo mshini ifakiwe. Ezifane akhethelwe kuphela iingcinga conductivity ophezulu. Lidla kukho izixhobo kwi emarikeni kunye wokwephuka ezimbi. Okokuqala, iingcali zithi ukuba akukho ngxaki ngamaza ezimfutshane kunye inzuzo eliphezulu kakhulu. Ukusuka model izibalo ixhomekeke ngqo kubungakanani log-ngamaxesha eriyali.

ukuguqulwa nkqo

Amaninzi zifumaneka kwiivenkile nkqo log-ngamaxesha eriyali. imodeli ubalo lwenziwa ngokusekwa kubukhulu yokubeka. Nkqo uhlobo eriyali log-ngamaxesha ezenziwe reflectors of conductivity ezahlukeneyo. wenza Imifanekiso ukuba uqhagamshelane ezisebenza ngokubakho.

Ungafumana kwakhona & nbsp izixhobo ngaphandle yokukhulisa ezivenkileni. Njengomgaqo, babesebenzisa reflectors ezimfutshane, kunye imishini zichazwe uhlobo shortwave. Elona sivumelekile rhoqo eriyali kuxhomekeke kwizinto ezininzi. Kulo mzekelo, umsebenzisi kufuneka athathe ingqalelo kweelana le kugqame. Ukongeza, kuyimfuneko ukwazi uhlobo olwandisa. Imifanekiso zithengiselwa kunye izilawuli eziqhelekileyo.

Izixhobo 144 MHz

olu hlobo log-ngamaxesha eriyali yenziweyo namaqhosha elide, kunye imishini zisetyenziswa kunye exhasa. Umfuziselo standard ibandakanya isinxibelelanisi enye. Yokukhulisa kulo hlobo eriyali ungene iseti ngamaxesha bamandla ezahlukeneyo. Ngaphezu koko, kubalulekile ukukhumbula ukuba iinguqulelo zihlukile conductivity. Ezinye izixhobo zenziwa ikhawuntala. Baye kwanegalelo amanzi. Ngokuqhelekileyo, indlela ezakhiwe ngayo imveliso vibrator. Abanamalungelo zichazwe iyenzeka. Ukuba oyifunayo, i-eriyali uhlobo log-ngamaxesha enjalo ukwenza nawuphi na umntu. Kulo mzekelo, kubalulekile ukubala ubude yokubeka.

Ukuguqulwa at 145 MHz

Uthi TV yale hlobo kuphela reflectors dipole. Kulo mzekelo, imishini zisetyenziswa nge isilinganiso conductivity. Iingcali zithi akukho bathengi ulungiso kakhulu ezifanayo ezisebenza ngokubakho igxunyekwe. Reflectors kokuba zifakwe nezinye izinto. Side isekela kuba nkulu kakhulu. Kwakhona kuyaphawuleka umgangatho ophezulu uxhathiso kwi data log uhlobo eriyali ngamaxesha athile.

Ukuba oyifunayo, imodeli ke ndawonye ekhaya. Iingcali le njongo ezizizithuba zesinyithi, apho amaqhina oqhagamshelwano phakathi ngokusebenzisa inverter welding. Le vibrator isetyenziswa ne imveliso enye. Ucingo eriyali zigxunyekwe olwandisa. Ngokuqhelekileyo, oko elapha ezantsi imasti.

Model ne andizele zobhedu

A log-ngamaxesha eriyali T2 lwemasti yobhedu ngokuphawulekayo kwangawo ezitsho ezahlukeneyo. imodeli Standard iquka pin iadaptha leyo busisigxina ezantsi yokubeka. Imishini njengezibonelo kusebenza kuphela olwandisa. Kufuneka kuqatshelwe ukuba ivenkile sine-eriyali kunye reflectors ububanzi. Abaninzi kubo nga esebenzisekayo ezitsho eliphantsi. Iingcali zithi ukuba kukho isixhobo olubuyiselwe nokwehlukana. Kuba ezi extenders zisetyenziswa kunye reflectors contact. Ezinye iimodeli baxhotyiswa yokukhulisa, abaqhagamshelwe sub.

Devices ne andizele intsimbi

antenna Log-ezuza imasti sentsimbi kungenziwa ngokuzimeleyo. Iingcali bacebisa ukuba le isivuno inkxaso ebanzi. imifuziselo ezininzi conductivity eliphezulu, yaye awunankinga ngokwenza umqondiso. Imishini zisetyenziswa imifuziselo njengezinobugcalagcala ezahlukeneyo. Kulo mzekelo, i yokukhulisa ngokuqhelekileyo efakwe kwi ezantsi imasti. Iingcali zithi ukuba kuyimfuneko ukulungisa zombini kuphela transistor kunye supply namandla.

Ngaphezu koko, kubalulekile ukuqaphela ukuba xa imodeli ibandla kungabangela iingxaki nalo umi. Xa siqwalasela eriyali webiwa, banalo onelungelo enkulu. Uthe inkxaso ngaphambili ngokuchanekileyo ngqo kwisixhobo useko lwemasti.
