Antenna apakhungu ndizogwiritsidwa ntchito ndi anthu kuti alandire zizindikiro zapadera kuchokera ku ma TV. Kuti mugwiritse ntchito antenna, televizioni yanu iyenera kukhala ndi chojambulidwa mkati kapena muyenera kukhala ndi ngodya yakunja yogwirizana ndi antenna ndi televizioni.
Digital kapena HD Antennas
Palibenso chinthu chofanana ndi chidziwitso cha digito kapena yapamwamba. Federal Communications Commission (FCC) imati aliyense amene ali ndi nyanga yomwe imatha kulandira chizindikiro cha analog ayenera kugwiritsa ntchito antenna yomweyo kulandira chizindikiro cha digito.
Zotsatira zake, zimayesedwa kuti muyesere kugwiritsa ntchito antenna yanu yakale musanagule antenna yogulitsidwa ku phwando la HD . Ngati antenna yanu sichigwira ntchito ndiye kuti mungafunikire imodzi ndi kukulitsa, zomwe zimathandiza kuti antenna atenge chizindikiro chabwino.
Buku Lopatulika Antennas
Antennas omasulira amagetsi amachulukitsa kuti alandire chizindikiro chofooka. Nkhonozi ndi zabwino makamaka kwa anthu okhala kumidzi chifukwa chizindikiro cholowera chingakhale chofunikira.
"Amplification amafunikanso pa nthawi imene pali utali wotalika kapena zingapo zing'onozing'ono pakati pa antenna ndi TV ," anatero Ron Morgan, katswiri wamaluso wothandizira pa Channel Master. "Kuonjezera mphamvu yamagetsi mphamvu yoyenera yachitsulo ndichofunika. Ngati mutayamba ndi antenna yolakwika, mudzakhala mukulimbana ndi nkhondo. "
Zovala zapanyumba zakunja
Wina anganene kuti $ 20 antenna m'katimo amagwira ntchito monga $ 100 pogona-mount model . Zonse zimadalira kumene munthu amakhalamo mogwirizana ndi mphamvu ya chizindikiro kuchokera ku nsanja za TV.
Malingana ndi Antenna Web, malo omwe amatsogoleredwa ndi Consumer Electronics Association, kusankha bwino kwa antenna sikungokhala patali kuchokera pa sitima yoyendetsera. Komanso zimakhazikitsidwa posonyeza zizindikiro za chizindikiro ndi kusankha chingwe chomwe chimagwira ntchito.

UHF ndi VHF
Antennas ali mkati kapena kunja. Mwa mkati, izi zikutanthauza kuti antenna ili mkati mwa nyumba. Momwemonso, ma antennas akunja adzakwera pamwamba pa denga, kumbali ya nyumba kapena nyumba yapamwamba.
Mitundu yonse ya maina omwe amatha kulandira chizindikiro chabwino amayang'ana patali kuchokera pa nsanja yotumizira komanso zovuta zilizonse pakati pa antenna ndi nsanja. Antenna zakunja nthawi zambiri zimakhala zamphamvu kuposa nyerere zamkati zomwe zimakhala zodalirika.
UHF ndi VHF
Manambala ambiri amalandira UHF, VHF kapena mitundu yonse ya zizindikiro. UHF ndi VHF zikufanana ndi AM ndi FM pa wailesi . Choncho, ndizofunikira kusankha chingwe chomwe chikugwirizana ndi zosowa zanu. Ngati mukufuna foni 8 ndiye mukufuna kupeza nthata yomwe imalandira VHF. Zomwezo zikanakhala zoona kwa UHF ndi channel 27.
Federal Communications Commission imati gulu la VHF liri pakati pa chingwe 2 ndi 13, kapena maulendo 54 - 216 Mhz . Zizindikiro za UHF zimaphimba njira 14 mpaka 83, kapena maulendo 300 - 3,000 Mhz, ngakhale chiwerengero chapamwamba chikhalapo kapena chidzasinthidwa ndi kusintha kwa digito.
Pali malingaliro omwe anthu amakhulupirira kuti zizindikiro zonse zamagetsi kapena zapamwamba zimalowa mkati mwa Bandwidth UHF. Ngakhale kuti UHF ikhoza kukhala ndi zizindikiro zambiri zamagetsi, pali zizindikiro zamagetsi ndipamwamba pa VHF band. Ndicho chifukwa chake tikulimbikitsira kugwiritsa ntchito chida chachitsulo cha AntennaWeb.org.
