Kwezi ndawo zelizwe, umqondiso womabonwakude ungathathiwe ngaphandle kwe-Amught: Kude kakhulu kwi-respt, isiqabu ihlala inesibindi, kwaye imithi iphazamisa. Kumgangatho oqhelekileyo "wemifanekiso", ufuna i-eriyannas .to, onokuthi okungenani athathe i-iron yomthengisi, unokwenza i-eriyali yokunika ngezandla zakho. I-Aesthetics ngaphandle kweSixeko ayifani, eyona nto iphambili - umgangatho wokwamkela, uyilo olulula, iindleko eziphantsi kunye nokuthembeka. Ungazama kwaye uzenze ngokwakho.
I-antenna elula yeTV
Ukuba umphinda-phinda ungaphakathi kwe-30 km ukusuka kwi-cottage yakho, unokwenza eyona ilula kwinxalenye yoyilo. Ezi ziityhubhu ezimbini ezifanayo zidityaniswe yintambo. Iziphumo zentambo zondliwe kwigalelo elifanelekileyo likamabonwakude.
Uyilo lwe-eriyali yeTV elizweni: Yenza ukuba ulula kakhulu (ukonyusa ubungakanani bomfanekiso, cofa kuyo ngeqhosha lasekhohlo)
Yintoni efunekayo ekwenzeni la magazini i-antetena
Okokuqala, kufuneka uyazi ukuba ubudlelwane bamabonakude bufutshane busasazwa. I-frequenc ixhomekeke kubude be "usov". Iqela losasazo likuluhlu lwe-50 ukuya kwengama-30 mhz. Yahlulahlulwe ziziteshi ezili-12. Kwi-teube nganye ifuna ubude bayo. Uluhlu lweendlela zamabonwakude ezibalulekileyo, ii-frequency zabo kunye neeparameter ze-eriyali kamabonwakude zokuzikhethela ziya kukhokelela etafileni.

Ke, ukuze enze i-eriyali yeTV ngezandla zakho, ufuna ezi zinto zilandelayo:
- Umbhobho wesinyithi onobude obuyi-6-7 cm mfutshane kunokuba kuchaziwe kwitafile. Izinto-nasiphi na isinyithi: ubhedu, intsimbi, idrarum, njl. Ububanzi-ukusuka kwi-8 mm ukuya kwi-24 mm (ngakumbi ibeka i-16 mm). Eyona meko iphambili: I-USA "i-USA" ifanele ibe njalo: ukusuka kwenye into, ubude, ukusuka kumbhobho wobubanzi obunye nobumnyama obunye.
- Intambo yeTV yokumelana nee-OOHMS ezingama-75. Ubude bayo buzimisele kule ndawo: ukusuka kwi-eriyali ukuya kwiTV, kunye nemitha yelinye elinesiqingatha ukuya kwi-fact kunye nesiqingatha semitha yelogo yonxibelelaniso.
- Isiqwenga se-tectolite ye-tectolite okanye i-Getynaks (ubukhulu be-4 mm),
- I-clamps ezininzi okanye imitya yentsimbi yemibhobho ebolayo kumnini.
- Intonga ye-Antenna (umbhobho wensimbi okanye ikona, ngaphandle kokuphakama okuphezulu kakhulu - ibha yomthi, njl. Njl.).
I-antenna elula ye-Cottage: Nokuba isikolo sekhaya sinokwenza ngezandla zabo
Kuya kuba kuhle ukuba nentsimbi engekhoyo, i-flux yokuthengisa ubhedu kunye nonxibelelwano: Iindawo zeziqwenga emva koko kufuneka zikhuselwe kwi-oxidation: Kungcono ukuba ugalele isilika, kunokwenzeka - i-epoxy rester, njl. Njengendawo yokugqibela-yithabathe iteyiphu, kodwa ayithembeki kakhulu.
Eli nqaku lasekhaya le-Intanethi leTV, nasekhaya, iya kwenza umntwana. Kuya kufuneka usike ityhubhu yelo xesha, ehambelana ne-frequency yosasazo, emva koko usike ngqo kwisiqingatha.
INdibano yoku-odola
Iityhubhu ezibangelwa zixoxwa kwelinye icala. Ezi ziphelo ziqhotyoshelwe kumnini-isiqwenga se-hetinaks okanye i-verictolite ene-4-6 mm (jonga umfanekiso). Iityhubhu zikwi-6-7 cm ukusuka kwelinye, ukuphela kwabo kumgama omde kufuneka kube kumgama ochazwe kwitafile. Bamiselwe kumnini, kufuneka bagcinwe ngokuqinileyo.I-vibrator efakiweyo ixhonywe kwimast. Ngoku kufuneka uqhagamshele kabini "i-USA" ngesixhobo esifanayo. Le yi-coop yentambo ngokuxhathisa kwee-OOHMS ezingama-75 (uhlobo rk-1, 3, 4). Iiparamitha zayo ziboniswe kwikholamu efanelekileyo yetafile, kwaye yenziwa njani - kwicala lasekunene lefoto.
I-carins ephakathi ye-cable ikhutshiwe (ithengiswa) kwimiphetho ekhutshiweyo yeetyhubhu, ibraid yabo iqhagamshelwe sisiqwenga somfundi omnye. Fumana i-wire nje: Sika isiqwenga sethambeka kancinci kunesayizi enqwenelekayo kwaye simahla kuzo zonke iigobolondo. Iphela icocekile kwaye iboshwe kwintambo yentambo (isixa esingcono).
Emva koko abaqhubi abasebasiki baqhagamshelwe kwiZiqwenga ezibini zokuthelekisa i-loop kunye nentambo eya kwiTV. I-Braid yabo idibene nentambo yobhedu.
Inyathelo lokugqibela: I-lop embindini ixhonywe kwintonga, ikwakhanyisiwe ezantsi kwintambo yehla. Ibha iphakanyisiwe kubude obufunayo kwaye kukho "ukusekwa". Ngoqwalaselo, abantu ababini bafuna: umntu uguqula i-eriyali, owesibini ubukele umabonwakude kwaye uvavanya umgangatho womfanekiso. Ukugqiba kwelokuba lo mqondiso ufumanekayo, i-eriyan eyenziwe ngezandla zayo ihleli kwesi sikhundla. Ukungakhathazeki ixesha elide nge "Setup", bona apho abafumana khona abamelwane (i-eriyan eyimfuneko) babhekiswa kuyo. I-eriyali elula yokupha ngezandla zakhe yenziwa. Faka kwaye "ubambe" indlela yokuyiguqula ngokuyiguqula ecaleni kwe-axis yayo.
Malunga nendlela yokusika intambo ye-ableal bukela ividiyo.

I-loop yombhobho
Le rintena yokupha ngezandla zakho inzima kancinci kwimveliso: Udinga i-bender ye-punde, kodwa irediyo yokwamkelwa ingaphezulu kwe-40 km. Izinto eziziimvelaphi zifana: ityhubhu yentsimbi, intambo kunye nentonga.
I-radius yombhobho we-bend iyabonakala. Kuyimfuneko ukuba umbhobho ubude obufunayo, kwaye umgama phakathi kweziphelo yayingama-65-70 mm. Zombini "amaphiko" kufuneka zifane, kwaye iziphelo kufuneka zilingane malunga neziko.
I-TV yaseKhaya eWenade i-eriyali efumana i-radius yokufumana ukuya kwi-40 km ukusuka kwi-40 km ukusuka kwisiqwenga sombhobho kunye nentambo (ukwandisa ubungakanani bomfanekiso, cofa kwisitshixo semouse)
Ubude bombhobho kunye nentambo ziboniswe kwitafile. Funda, ngaluphi usasazo olufutshane olusondeleyo kuwe, khetha umtya ofanelekileyo. Screw umbhobho wobungakanani obufunayo (ububanzi bunqwenelekayo 12-18 mm, iiparamitha zelog ezihambelana nayo zinikiwe).

Indibano
Ityhubhu yexesha elide elifunekayo lokugoba, lenza i-ivise i-symmetrical kwiZiko. Umphetho omnye ucekeceke kwaye waqhekezwa / utywina. Gcwalisa isanti, kwaye uvale icala lesibini. Ukuba akukho hlathi, ungajikela iziphelo, faka iiplagi kwiglue elungileyo okanye i-silicone.Umdibaniso womphumo ulungisiwe kwi-MAST (yeROD). Kukrwelwe ukuya kwiziphelo zombhobho, kwaye emva koko oovimba abakumgangatho welog yelog kunye nentambo, eya kwiTV iyadideka. Inyathelo elilandelayo kukuqhagamshela iqhekeza le-wirer yobhedu ngaphandle kokufakwa kweentambo ze-braid. Indibano igqityiwe- ungaqala "ubumbeko".
Ukuba ufuna ukuyenza ngokwakho, funda indlela yokukhetha i-eriyali yokupha apha.
Ibhasikithi e-Antenna
Ngaphandle kwento yokuba ijongeka ngaphandle, umfanekiso ubangcono kakhulu. Iqinisekisiwe ephindaphindiweyo. Zama!
I-antenarna yangaphandle ukusuka kwi-beer cans
Isidingo:
- Iitoti ezimbini eziqinileyo ngamandla eelitha ze-0,5,
- isiqwenga somthi okanye ngeplastiki malunga ne-0.5 yeemitha ubude,
- Isiqwenga se-wire ye-TV-58,
- Ukurhweba ngentsimbi
- I-Aluminium Bux (ukuba i-aluminium Cans),
- Ithembeko.
Indlela yokwenza i-eriyali evela kwiitoti
Siqokelela ngoluhlobo:
- Ezantsi kweebhanki ze-Banks ngokungqongqo okanye i-5-6 mm ubukhulu).
- Ngalo mngxunya, wolula intambo, ngaphandle komngxunya kwisivalo.
- Le bhanki ilungisa ngasekhohlo kumnini ukuze intambo ithunyelwe embindini.
- Ndikhupha intambo kwiBhabheli malunga ne-5-6 cm, susa i-insumpass malunga ne-3 cm, siyayithoba isalali.
- Ukusika i-braid, ubude bayo bube malunga ne-1.5 cm.
- Isasazwa ngaphezulu komphezulu we-can kunye nomthengisi.
- Umqhubi wendlela ophakathi onamathela kwi-3 cm kufuneka ithengiswe ezantsi kwebhanki yesibini.
- Umgama phakathi kweebhanki ezimbini kufuneka zenziwe ezincinci kangangoko kunokwenzeka kwaye ulungise nangayiphi na indlela. Enye yeendlela zokukhetha i-tepiy thepe okanye iteyiphu.
- Zonke, i-antenna ye-Anten ye-DMV ilungile.
Isiphelo sesibini sentambo sigqityiwe ngeplagi efanelekileyo, vula i-tv jack. Lo uyilo, ngendlela, lunokusetyenziselwa ukufumana umabonwakude. I-fir yakho ixhasa le fomati yomqondiso (i-DVB T2) okanye kukho i-console ekhethekileyo kwiTV yakudala, ungayifumana umqondiso kwi-restere ekhoyo. Kuya kufuneka ukuba wazi kuphela apho ifumaneka khona kwaye uthumela i-eriyali yakho, eyenziwe ngezandla zakho kwi-TIN.
I-antenas elula yasekhaya inokwenziwa kwiitoti ze-tin (ukusuka phantsi kwebhiya okanye iziselo). Ngaphandle kokumangaliswa kwezinto "zezinto" kusebenza kakuhle, kwaye yenziwe kakhulu
Uyilo olufanayo lunokuhlengahlengiswa ukuze ufumane amajelo emisele. Endaweni ye-0.5 yeelitha, faka i-1 ilitha. Uya kuthatha uluhlu lwe-MV.
Enye inketho: Ukuba akukho sinyithi sokuthengisa, okanye awuyazi indlela ebhetele ngayo irhwebi, unokwenza kube lula. Iibhanki ezimbini zibotshwe kumgama weesentimitha ezininzi ukuya kumnini. Ukuphela kwentambo kucociwe ngeesentimitha ezili-4-5 (susa ngononophelo i-insultiment). I-braid yahlulwe, ubotshelelwe kwi-harness, wenza iringi kuyo, apho ukuzixhasa khona. Ukusuka kumqhubi ophakathi wekopi, yenza iringi yesibini kwaye uyikhuphe isikrelemnqa wesibini. Ngoku emazantsi eetoti enye esicoca i-sped, apho izikrike zikrelekrele.
Ngapha koko, ukuba uqhagamshelo olungcono lufuna ukuba kuthengiswe: Inqwelomoya ye-Braid kungcono ukuthumela kwaye i-SOB, njengendawo yokunxibelelana neetoni zentsimbi. Kodwa kwakhona kukuziqula, kuyavela ukungalunganga, nangona kunjalo, unxibelelwano oluthile ngamanqanaba aphezulu kwaye kufuneka lucocwe. "Ikhephu" uya kwazi ukuba kutheni ...
Mhlawumbi uyazibuza ukuba yenze iBrazier kwibhaluni okanye kwimibala, unokufunda ngayo apha.
I-eriyali yeTV yedijithali yenze ngokwakho
Uyilo lwe-Ariyanna-Isakhelo. Ngolu khetho lwesixhobo sokufumana uyakufuna umpheleli kwiibhodi zokhuni kunye nentambo yeTV. Sikwafuna iteyiphu, iinzipho ezininzi. Yonke into.Sele sitshilo ukuba ukufumana isiginali yedijithali, kuphela i-entenna ye-entenna iyafuneka kunye ne-Decoder ehambelanayo. Inokwakhiwa kwithelevishini (isizukulwana esitsha) okanye eyenziwe ngendlela yesixhobo sehotele. Ukuba umsebenzi wokwamkela umqondiso kwikhowudi ye-DVB T2 kwi-tv ukhoyo, qhagamshela i-antenna kwangoko kwiTV. Ukuba akukho decoder kwiTV, kuya kufuneka uthenge isimemo sedijithali kwaye uqhagamshele e-eriyali kuyo, kwaye kukwi-tely.
Uthatha isigqibo malunga nejelo kwaye ubale i-perimeter yesakhelo
ERussia, kwamkelwa inkqubo, apho kwakhiwa khona iitrone. Ekupheleni kuka-2019, wonke umda kufuneka ugutyungelwe ngabaphindayo. Kwiwebhusayithi esemthethweni: //xn--p1aads.xn--p1ai/when/ fumana inqaba yakho ekufutshane nawe. Kukho irenti yosasazo kunye nenombolo yejelo. Umjikelezo wefreyithe ye-eriyali kuxhomekeke kwinombolo yetayile.
Oku kujongeka njengenombolo yombona we-tegital
Umzekelo, kwi-37 usasazo lwentsholongwane lwenziwa rhoqo kwi-602 MHz. Amaza amade athathwa njengowalandelayo: I-300/602 = 50 cm. Lo iya kuba ngumjikelezo wesakhelo. Bala ngokufanayo nakwelinye ijelo. Mayibe ziindlela ezingama-22. Rhoqo 482 MHz, wavelengt 300/482 = 62 cm.
Kuba le nqaku le-eriyali iqulethe iifreyimu ezimbini, ke ubude bomqhubi kufuneka zilingane ne-wavelength ephindwe kabini, kunye ne-5 cm kunxibelelwano:
- Ngeendlela ezingama-37, sithatha i-105 cm yocingo lwe-wire (50 cm * 2 + 5 cm = 105 cm);
- Iindlela ezingama-22 zifuna i-129 cm (62 cm * 2 + 5 cm = 129 cm).
Mhlawumbi unomdla ngakumbi ukusebenza nomthi? Indlela yokwenza igumbi libhaliwe apha kwaye malunga nokwenziwa kwe-booth yenja - kweli nqaku.
Indibano
Ucingo lobhedu lusetyenziswe kakuhle kwintambo, eliza kuqhubeka nokufumana umamkeli. Oko kukuthi, thabatha intambo kwaye ususe iqokobhe kwaye yintsimbi kuyo, ikhulula umyinge ophakathi owufunayo. Yenza ngononophelo ayinakwenzakele.
Emva koko, sakha inkxaso evela kwiiBhodi, njengoko kubonisiwe kumzobo. Ukwenza oku, kubalulekile ukumisela ubude becala lesakhelo. Kuba iguqulwe isikwere, emva koko i-perimeter yahlulwa ngu-4:
- Ngeendlela ezingama-37: 50 cm / 4 = 12.5 cm;
- Kwiindlela ezingama-22: I-62 cm / 4 = 15.5 cm.
Umgama ukusuka kwisikhonkwane ukuya kwenye kufuneka ihambelane nale parameter. Ukubekwa kocingo lobhedu luqala ngasekunene, ukusuka embindini, kuhamba phantsi emva koko kubo bonke amanqaku. Kuphela kwindawo apho iifreyimu zilungele enye kwenye, musa ukuqaqambisa abaqhubi. Bafanele ukuba bakumgama othile (2-4 cm).
I-eriyali yasekhaya ye-targial ye-digital
Xa yonke i-perimeter ifakwe, i-braid evela kwintambo ixesha elide kwiisentimitha ezininzi ijijekile kwi-harness kunye negosa elithile (lalityelwa, ukuba ayisebenzi) kumda ochaseneyo wesakhelo. Ngapha koko, intambo ibekwe njengoko kubonisiwe kumzobo, ukuyilisela i-tepi (inokuba njalo, kodwa i-itch ayinakutshintshwa). Emva koko intambo iya kwi-decoder (eyahlukileyo okanye eyakhiwe). Yonke i-eriyali yokupha ngezandla zakho ukuze yamkele umabonwakude.
Ungayenza njani i-eriyali ye-tmando yedijithali enezandla zakho - enye uyilo lubonisiwe kwividiyo.
