Kuti muwone TV pa TV, muyenera kulumikiza ku antenna. Zili choncho chifukwa pazifukwa zina mulibe nyongolosi: mwina simungakhale ndi chikhumbo kapena njira yobwezera mautumiki a televizioni, kapena inu muli kutali kwambiri ndi mzinda, kumene TV siidzawonetsera popanda kunja kulandira chizindikiro mu mawonekedwe a antenna.
Kuti muwone TV, mumasowa antenna. Inde, ngati pali njira zosavuta komanso mofulumira kugula mu sitolo. Koma mukhoza kupita njira ina. Za momwe mungapangire antenna ya TV ndi manja anu omwe adzauzidwa.
Ngati mumapanga chingwe chaching'ono, mungathe kuwona zochepa zazitsulo za TV komanso zovuta kwambiri, koma mwamtheradi.
Indoor HDTV Antenna
Podzipanga nokha, mungalandire chizindikiro kuchokera ku televizioni pa 470-790 MHz.
Musanayambe kupanga chingwe kuchokera ku waya, zipangizo zotsatirazi ziyenera kukonzekera:
- mpeni;
- Scotch tepi;
- wosakaniza;
- chikuda;
- chomatira;
- mkasi;
- chizindikiro;
- chojambula;
- makatoni.
- Sindikirani papepala ndikuchidula.
- Dulani chikwangwani chokhala ndi masentimita 35 (kutalika) ndi 32.5 masentimita (m'lifupi). Timamangiriza ndi zojambulazo.
- Timayang'ana pakati ndikudula tizigawo ting'onoting'ono tiwiri tating'ono.
- Kuchokera muzithunzi zomwe timapanga kuchokera pa makatoni.
- Mukhoza kujambula mfundo mu mtundu uliwonse.
- Tsopano tulani chitsanzo chojambula.
- Pogwiritsa ntchito phokoso pamphuno, pangani kanyumba kakang'ono.
- Timagwiritsa ntchito zojambulazo pa antenna vibrator, yomwe imatchedwa "butterfly".
- Tiyeni tiyambe kusonkhanitsa antenna. Pa mtunda wa masentimita 3.5 kuchokera kuwonetsera timagwiritsa gulugufe.
- Pakati pa gulugufe timakoka mabowo kwa chingwecho.
- Tikayika transformer yofananako kuyambira 300 mpaka 75 Ohm.
- Antenna yogwiritsira ntchito kunyumba ndi okonzeka.

Antenna kwa dacha manja
Antenna ku nyumba yachilimwe imapangidwa ngati mawonekedwe. Poyamba timakonza zolemba:
- waya wamkuwa uli ndi mamita 4 mm ndi kutalika kwa mamita anayi;
- chokhala ndi bolodi la masentimita 7 ndi kutalika kwa masentimita 55;
- pulagi;
- mipiringidzo khumi;
- wolamulira;
- pensulo yosavuta;
- tepi yamentimenti;
- chitsulo chosungunula.
1. Kuchokera pa bolodi timapanga workpiece molingana ndi ndondomeko zotsatirazi.
2. Zing'onoting'ono pa chithunzicho ndi inchi. Ayenera kumasuliridwa mu masentimita:
- 3/4 "= 2 masentimita;
- 1 "= 2.5 masentimita;
- 2 "= 5 masentimita;
- 2 5/8 "= 6, 66 cm (akhoza kupanga 6.5 cm);
- 5 ¼ "= 13, 33 cm (do 13 cm);
- 22 "= 55 masentimita.
3. Mkuwa wamkuwa umadulidwa ndi mamita asanu ndi atatu (37.5 cm) iliyonse (masentimita 15).
4. Pogwirizana ndi zam'tsogolo, pakati pa waya aliyense ayenera kuchotsedwa.
5. Dulani mawaya awiri a masentimita 22 ndikuyeretsa pamphambano.
6. Zingwe zina zimawerama ndi kalata "V". Mtunda pakati pa malekezerowo uyenera kukhala masentimita 7.5.
7. Sonkhanitsani antenna monga momwe taonera pa chithunzi pansipa.
8. Tengani pulagi ndi kulumikiza antenna ndi chingwe.

9. Pansi pa coil iyenera kugulitsidwa ku chingwe.
10. Onjezani pulagi ku bolodi.
11. Antenna kulandira chithandizo cha TV m'dzikoli ndi wokonzeka kulandira chizindikiro.
Momwe mungapangire mtengo wa antenna?
Ngati mumagwiritsa ntchito antenna yokhazikika, muyenera kugwiritsa ntchito kansalu kwa chida chake chakunja. Mukhozanso kudzipanga nokha. Kwa ichi, mapaipi amkuwa ndi abwino.
- Timatenga mapaipi awiri ndikukumba pansi.
- Timakoola mabowo kumbali zonse ndikuyika barani yothandizira zitsulo.
- Pa ndodo "chingwe" mbozi wokha kapena malaya a chitoliro.
- Mmanja awa, mukhoza kuyika nambala iliyonse ya mapaipi. Timayika nawo ndi chingwe chachitsulo. Motero, kutalika kwa kansalu kokonza antenna kungapangidwe kulikonse mwa kukulitsa ndi mapaipi ena.
Pangani antenna nyumba kapena nyumba sivuta. Zokwanira kukhala ndi zipangizo zofunika. Ndipo nthawi yopanga sipangakhale yoposa 30 minutes. Koma mudzakhala ndi chipangizo chothandizira kulandira chizindikiro cha TV, chopangidwa ndi inu nokha, ndipo funso lidzathetsedwa, kusiyana ndi kutenga mwanayo mvula yamvula ..
