DIY ita-iwe-iwe pachako terevhizheni antenna yedhijitari terevhizheni: zviyero, dhayagiramu yakapusa, yekunze uye yemukati antenna yedhijitari terevhizheni, yakagadzirwa newe. Munguva pfupi yapfuura, terevhizheni yakaonekwa muhupenyu hwemunhu. Kwemakore anoda kusvika zana muchokwadi chedu kwave kune chinhu chakadai seTV. Kubva pakugadzirwa kwavo kusvika nguva pfupi yadarika, materevhizheni ave achifambiswa neanalog chiratidzo tekinoroji. Musiyano mukuru kubva kurudzi rwemazuva ano rwechiratidzo chinoshandiswa, dhijitari, ndiko kuendesa magetsi kune anogamuchira. Iyi magetsi inoenderana neimwe frequency uye amplitude, iyo inozoshandurwa kuita mufananidzo uye ruzha. 
Mutengo wayo wakaderera zvakanyanya pane wetambo yemhangura, asi ine zvimiro zvakafanana nemumwe kondakita anozivikanwa, yakajairika muinjiniya yemagetsi. Muzviitiko zvakanyanyisa, unogona kushandisa antenna yenguva dzose waya. Imwe antenna haina basa uye haina musoro pasina mamwe mashoko anobatsira kushandura chiratidzo chedhijitari kuita mufananidzo. Pamusoro pezvinhu zviri pamusoro apa zveantenna, iwe uchada:
- plug iyo inotumira chiratidzo kubva kune antenna kuenda kune inogamuchira;
- kana TV iri yemuenzaniso wekare – anogamuchira – anogamuchira;
- TV pachayo.
Unogona kupa izvo zvigadzirwa chimiro chaunoda uye kusungirira pasina maturusi akakosha. , asi kurerutsa basa uye kuchengetedza nguva, zvakakodzera kugadzirira pliers uye waya cutters, insulating tepi, uye soldering iron.
Mhando dzeantenna dzinogashira yemhando yepamusoro dhijitari chiratidzo chekuita-iwe-iwe pachako kugadzira
Sarudzo yakafara mutekinoroji yekugadzira antenna kubva kune yakagadziridzwa zvinhu inobvumidza iwe kuti uenderere mberi kubva pane zvaunokwanisa uye mamiriro. Zvinoitika kuti munhu haakwanisi kuwana mumuviri zvinhu zvinodiwa munguva pfupi iri kutevera. Zvishandiso zvakagadziridzwa zvinouya kuzonunura, izvo anenge munhu wese ane mugaraji. Antenna chimiro, mudziyo wakagadzirirwa kutora masaisai enhepfenyuro yeterevhizheni. Zvishandiso zvakagadzirirwa kushandiswa zvakajairika zvinokwanisa kutora frequency mumhando kubva pa41 kusvika 250 MHz. Izvo zvishoma, asi zvinogoneka, kuti antenna yekumba ichakwanisa kutora ekupedzisira-akakwira frequency masaisai, kubva pa470-960 MHz. Kutora zvishandiso zvakagadzirirwa terevhizheni, inogona kupatsanurwa muzvikamu zviviri – yemukati (iri pedyo neTV iri pedyo) uye yekunze (yakaiswa kunze kwechivako mune TV). 
Danho repiri Maererano nemavara abuda, komba waya pakona ye90°. Isu tinotengesa chete magumo emahara ewaya. Muchiitiko ichi, gaka rinofanira kuwanikwa pakati pemakona emukati: soldered uye bent. Danho rechitatuIyo antenna wire inoratidzirwa kubva kune rumwe rutivi ne 3-5 cm. Kuti uite izvi, kuvhara kwekunze kunobviswa zvakanyatsonaka, zvikamu zvemukati zvakakotama uye nheyo yepakati inosunungurwa. Iyo yepakati musimboti wewaya yakaputirwa pakona isina kutengeswa, uye chikamu chewaya chinotarisirwa chidzitiro chakaputirwa munzvimbo yakatengeswa. Zvakakosha kuita kuti mhepo igare yakasimba.
Danho rechina Chimiro chinoguma chewaya dzisina chinhu chinovharidzirwa nematepi emagetsi kana nepfuti yeglue. Plugi inonamirwa kune rumwe rutivi rwewaya kuti itumire chiratidzo kuTV. Chigadzirwa chacho chakagadzirira, mugumo wakakotama unosungirirwa pachigadziko. 
log-periodic antenna
Chinhu chikuru chekugadzirwa uku ndiko kurongeka kwemavibrators ehurefu hwakasiyana – ivo vakaiswa pane imwechete axis. Zviyero zvezvinhu zvese zvinoshanda zveiyo log-periodic antenna hazvifanirwe kupfuura nzvimbo yekuita uye kubata. Iyo log-periodic antenna ndiyo yakanakisa sarudzo yekuita pamba, sezvo ichipfuura mamwe marudzi mune ese maitiro, asi yakaoma kugadzira. Kuti uzviite iwe pachako, iwe unofanirwa kuva nemachubhu maviri esimbi (asina kana kuti kwete – hazvina basa, ikozvino inomhanya pamusoro pepamusoro). Iwe unofanirwawo kuva netambo dzemhangura dzehurefu hwakasiyana, iyo ichava zvikamu zvekugamuchira. Pazasi pane tafura ine yakagadzirira-yakagadzirwa macalculation inofanirwa kushandiswa pakugadzirira zvikamu zveamangwana chiratidzo chinogamuchira.
Isu tinogadzirira vibrator zvinoenderana nedata rakapihwa mutafura. Izvo zvakakosha kuti iyo dhayamita yakafanana kune yega vibrator. Iyo yekudyisa tambo inopfuudzwa nepakati peimwe yetsvimbo kana kungoita nerubatsiro rwefasteners, iyo inoitwa sezvinoratidzwa mumufananidzo uri pazasi.
Mushure maizvozvi, mavibrators anogadziriswa nesimbi yesimbi. Ita-iwe-iwe pachako ine simba log-periodic UHF antenna: https://youtu.be/txZJkjPkOoY
Wave
Haina kukodzera kugamuchira zviratidzo zvenguva refu uye ine zvishoma, asi dhizaini pachayo yakave yakakurumbira kubva pakugadzirwa uye kuparadzirwa kwemafungu eredhiyo muhupenyu hwezuva nezuva, uye ichiri kufarirwa. Iyo dhizaini ine akati wandei zvinhu: waya yemhangura (kana chubhu), mutungamiriri, reflector uye vibrator. Uyezve, chigadziko chinogadzirwa icho antenna yakapedzwa ichabatanidzwa (plastiki kana huni – hazvina basa, chinhu chikuru ndechokuti ive dielectric). Zvakakosha kuisa zvikamu panzvimbo yakaenzana kubva kune mumwe. Zvikamu zvakabatanidzwa maererano nemufananidzo uri pasi apa. 
Maitiro ekuvandudza mhando yechiratidzo pane antennas epamba
Pane zvikonzero zvakawanda nei chiratidzo cheTV chisina simba. Semuenzaniso, mhando yemufananidzo inowanzorasika kana ruzha rwakarasika nekuda kwekuti antenna inogamuchira chete chiratidzo chinoratidzwa. Zvimwe zvikonzero zvinogona kuva:
- kuderera kwekunzwa;
- high resistance cable;
- kureba kubva pashongwe yeTV;
Kuti uvandudze mhando yechiratidzo pane antennas epamba, unofanirwa kuyedza matanho anotevera:
- Kana iri mukati, saka unofanira kuiisa pedyo nehwindo sezvinobvira. Saka munzira yayo pachava nezvipingamupinyi zvishoma nekuda kwechikamu chipi chechiratidzo chakarasika.
- Kana iri mumugwagwa, unofanirwa kuiisa panzvimbo yakakwirira – padenga. Ita shuwa kuti chiratidzo hachivharirwe nemakomo kana masango.
- Chinja nzira. Kuvhiringidza uye kupararira kwemufananidzo kunowanzopera kana iwe ukashandura chigadziro chekugamuchira munzira yakarurama, kunyange makumi mashoma emadhigirii anoita basa.
- Tenga antenna amplifier.
Maitiro ekuverenga ma parameter e digital TV
Kune antenna kubva kune tambo, unofanirwa kuverenga kureba kwayo. Izvi zvinoitwa pachishandiswa zvakajairwa mafomula efizikisi. Kutanga iwe unofanirwa kunzwisisa kuti ndeapi mafrequencies iyo multiplex nhepfenyuro , mushure mezvo tinowana avhareji kukosha. Semuenzaniso, pamafrequency e605 uye 613 MHz, kureva arithmetic kunoratidzwa kuve 609 MHz. Danho rinotevera nderokuona hurefu hwemasaisai kuburikidza neformula yekumhanya kwechiedza yakakamurwa neinotorwa masvomhu zvinoreva. Kuverenga: 300/609 \u003d 0.492 m. Kubva pane inoguma nhamba tinoverenga 1/4, iyo ichava inodiwa urefu hwetambo kugadzira antenna. Kuti ufambise basa rekuverenga, unogona kushandisa online calculator iyo inonyatso kuverenga saizi inodiwa yehafu-wave, quarter-wave uye yakazara-wave antennas. Online Calculator muGoogle kana Yandex:
- dipole uye pini karukureta;
- Amateur radio Calculator.
Iyo yakanakisa kuzviita-iwe-iwe pachako antenna isina solder simbi yeT2 dhijitari terevhizheni: https://youtu.be/h7pcp-nvYqQ Kugadzira antenna nemaoko ako pachako hakuna kuoma, zvinonetsa kutengesa uye kubatanidza zvese zvese. kuitira kuti ishande pasina kukanganisa uye kupera kwemifananidzo. Nhasi hazvidikanwi kuenda kuchitoro uye kutenga zvigadzirwa zvinodhura, pane mamiriro ezvinhu apo zvisingakwanisi kusvika kuchitoro. Iwe unogona kugadzira antenna kubva kune yakagadziridzwa zvinhu. Tinokupa zano kuti usarudze chero dhizaini ye coaxial wire, kana “Eight”. Sezvinoratidzwa nemaitiro, ndiwo ari nyore kugadzira, uye maitiro avo anotendera kuti utarise TV chero kupi.
