Ngakho-ke, ukuze wenze i-antenna ye-TV ngezandla zakho, udinga izinto ezilandelayo:
- Ipayipi lensimbi elinobude obungu-6-7 cm lifushane kunokuchazwa etafuleni. Izinto ezibonakalayo - noma iyiphi insimbi: ithusi, insimbi, i-duralumin, njll. Ububanzi - kusuka ku-8 mm kuya ku-24 mm (kuvame ukubeka i-16 mm). Isimo esiyinhloko: Kokubili "i-USA" kufanele kube okufanayo: kusuka kokukodwa, ubude obuthile, kusukela kupayipi bodonga olulodwa nosayizi olinye odongeni.
- Intambo yethelevishini ngokumelana kwama-ahms angama-75. Ubude bawo bunqunywa kule ndawo: Kusuka e-antenna kuya ku-TV, kanye nemitha yengxenye eyodwa kuya kwengxenye kuya ku-sagging kanye nesigamu semitha yokuxhumanisa i-loop.
- Ucezu lwe-textolite noma i-GetYnaks (ubukhulu okungenani be-4 mm),
- Ama-clamp ama-clamp noma imichilo yensimbi yokuqinisa amapayipi kumuntu ophethe.
- Induku ye-antenna (ipayipi lensimbi noma ekhoneni, ngokungaphezulu okuphezulu kakhulu - ibha yokhuni, njll.).
I-antenna elula ye-cottage: Ngisho nesikole singenza ngezandla zazo
Kungaba kuhle ukuba nensimbi ethengisa i-iron, i-flux ye-soldering yethusi futhi i-solder: konke ukuxhumana kwabaqhubi abaphakathi kuyanyamalala: Ikhwalithi yesithombe izoba ngcono futhi i-antenna izosebenza isikhathi eside. Izindawo zezingcezu zidinga ukuvikeleka kwi-oxidation: Kuhle ukuthela ungqimba lwe-silicone, kungenzeka - i-epoxy resin, njll. Njenge-resort yokugcina - uyithathe ngetheyipu, kepha ayithembeki kakhulu.
Le antenna eyenziwe ekhaya ye-TV, ngisho nasekhaya, izokwenza ingane. Udinga ukusika i-tube yalolobude, ehambelana nemvamisa yokusakaza i-Pureter ephindayo, bese uyinquma ngqo phakathi.
Oda umhlangano
Amashubhu aphumela kuxoxwa ngakolunye uhlangothi. Le mikhawulo inamathiselwe kumnikazi - ucezu lwama-hetinaks noma i-textualite enobukhulu be-4-6 mm (bheka isithombe). Amashubhu atholakala kude ne-6-7 cm kusuka komunye nomunye, amathuba abo amade amade kufanele abe kude netafula. Zilungiselelwe kumnikazi, kufanele zigcinwe ziqinile.I-vibrator efakiwe ihlelwe ku-mast. Manje udinga ukuxhumanisa ama- "USA" amabili ngedivayisi yokuqhathanisa. Lokhu kungukulwa kwentambo okuphikisana nama-75 ohms (uhlobo RK-1, 3, 4). Amapharamitha awo akhonjiswa kwikholamu yesokudla ekwedlulele yetafula, nokuthi kwenziwa kanjani - ohlangothini lwesokunene lwesithombe.
Imithambo yekhebula elijwayelekile i-Screw (ithengiswe) emaphethelweni akhishwe amashubhu, i-braid yawo ixhumeke ngesiqeshana somqhubi wesifundo esifanayo. Thola ucingo kalula: Sika ucezu lomthambeka kancane ngaphezu kosayizi oyifunayo futhi ukhululekile kuwo wonke amagobolondo. Iphela ihlanzekile futhi ibopha ngentambo yekhebula (kangcono i-supay).
Ngemuva kwalokho abaqhubi abaphakathi baxhumeke kusuka kungcezu ezimbili zokufanisa i-loop nentambo eya kwi-TV. I-braid yabo nayo ixhumeke ngocingo lwethusi.
Isenzo sokugcina: I-loop maphakathi ilungiselelwe induku, nayo iklwebekile phansi kwikhebula lehla. Ibha likhuliswe endaweni ephakeme lapho "setha". Ukucushwa, abantu ababili badinga: umuntu ujika i-antenna, okwesibili ubukele i-TV futhi ahlole ikhwalithi yesithombe. Njengoba sinqume ukuthi isinali litholakala kuphi, i-antenna eyenziwe ngezandla zayo ihleliwe kulesi sikhundla. Ukuze ungahlupheki isikhathi eside ngokusetha "setha", bheka lapho abamukelayo komakhelwane (abalulekile) baqondiswa. I-antenna elula kunazo zonke yokupha ngezandla yenziwa ngezandla zakhe. Faka futhi "Bamba" ukuqondiswa ngokuyiguqula ngendlela yayo.
Mayelana nokuthi ungasika kanjani ikhebula le-coaxial video.

- Konke, i-Antenna DMV eyenziwe ekhaya ilungile.
Isiphetho sesibili sekhebula sesiqediwe nge-plug efanele, vula i-TV jack. Lo mklamo, ngendlela, ungasetshenziselwa ukuthola ithelevishini yedijithali. I-FIF TV yakho isekela le fomethi yesiginali (DVB T2) noma kukhona ikhonsoli ekhethekile kwi-TV yakudala, ungabamba isiginali kusuka kukuphinda okuphindayo okuseduze. Udinga nje kuphela ukwazi ukuthi itholakala kuphi futhi lapho ukuthumela i-antenna yakho yethelevishini, yenziwe ngezandla zakho kumathini we-tin.
Ama-antennade alula ekhaya angenziwa kusuka kumathini we-tin (kusuka ngaphansi kukabhiya noma iziphuzo). Naphezu kokuphazamiseka kwe- "Izakhi" kusebenza kahle kakhulu, futhi kwenziwa nje
Umklamo ofanayo ungashintshwa ukuze uthole iziteshi zesiteshi semitha. Esikhundleni samathini angu-0.5 litre, beka ilitha eli-1. Kuzothatha uhla lwe-MV.
Enye inketho: Uma kungekho i-iron elungiselelwe, noma ungazi ukuthi ungasondelela kanjani, ungenza kube lula. Amabhange amabili aboshelwa ebangeni lamasentimitha amaningana kwisibambi. Ukuphela kwentambo kuhlanzwa ngamasentimitha angama-4-5 (susa ngokucophelela ukufakwa). I-braid ihlukaniswe, uboshelwe kuma-harness, wenza indandatho kuyo, lapho ukusekela khona. Kusuka kumqhubi weCentral, yenza indandatho yesibili futhi kuyo isikulufa sesibili sokuzishaya. Manje ezansi kweyodwa amathini sihlanza ucezwana, lapho izikulufo zihlungile.
Eqinisweni, ukuthintana okungcono badinga i-soldering: ukuthwala i-braid kungcono ukuthumela nokukopisha, njengendawo yokuxhumana ne-Metal Cans. Kepha futhi ngokuzikhandla, kepha akukubi, nokho, oxhumana naye ngeke ahlanzeke. "Iqhwa" lizokwazi kanjani ukuthi kungani ...
Mhlawumbe uzibuza ukuthi ungayenza kanjani iBrazier kusuka kubhaluni noma imiphongolo, ungafunda ngakho lapha.
I-Antenna ye-TV yedijithali yenze ngokwakho
Umklamo we-antenna - uzimele. Ngale ndlela yokwamukela idivaysi uzodinga i-crostordon kusuka emabhodini ezinkuni kanye nekhebula lethelevishini. Sidinga neteyipu, izipikili eziningana. Konke.Sesivele sikushilo ukuthi ukuthola isiginali yedijithali, kudingeka i-decimeter anternet kuphela kanye ne-decoder ehambisanayo. Ingakhiwa kumathelevishini (isizukulwane esisha) noma yenziwe ngesimo sedivayisi yehhotela. Uma umsebenzi wokwamukela isiginali kukhodi ye-DVB T2 kwi-TV ukhona, xhuma i-antenna ngokushesha kwi-TV. Uma kungekho decoder ku-TV, uzodinga ukuthenga isiqalo sedijithali bese uxhuma kwi-antenna kuyo, futhi kuya ku-ngocingo.
Unganquma kanjani esiteshini bese ubala i-perimeter yohlaka
ERussia, kwamukelwa uhlelo, lapho imibhoshongo yakhiwa njalo. Ekupheleni kuka-2019, yonke insimu kufanele imbozwe ngabaphindaphindayo. Kuwebhusayithi esemthethweni ye-http: //xn--p1aadc.xn--p1ai/wn/ww / Thola umbhoshongo wakho oseduze kwakho. Kukhona imvamisa yokusakaza nenombolo yesiteshi. I-perimeter yohlaka lwe-antenna incike kwinombolo yesiteshi.
Lokhu kubukeka njengenombolo yethelevishini yedijithali
Isibonelo, ekusakazweni kwesiteshi esingu-37 kwenziwa ngokuvama kwe-602 MHz. Igagasi elide libhekwa njengokulandelayo: 300/602 = 50 cm. Lokhu kuzoba umjikelezo wohlaka. Bala okufanayo nesiteshi. Akube iziteshi ezingama-22. Imvamisa u-482 MHZ, wavength 300/482 = 62 cm.
Njengoba le antenna inamafreyimu amabili, khona-ke ubude bomqhubi kufanele bulinganiswe ne-wavelength ephindwe kabili, kanye ne-5 cm ekuxhumekeni:
- Ngeziteshi ezingama-37, sithatha i-105 cm yocingo lwethusi (50 cm * 2 + 5 cm = 105 cm);
- Iziteshi ezingama-22 zidinga i-129 cm (62 cm * 2 + 5 cm = 129 cm).
