Udinga i-antenna ekhethekile ukuthola umsakazo we-satellite . Umsakazo wakho wemoto ngeke uwunqume ngoba, ngokungafani nomsakazo we-FM nomsakazo we- HD , umsakazo we-satellites kanye nomsakazo we-FM awusakazwa emagatsheni afanayo. Yingakho awudingi i- antenna ye-HD ekhethekile, kodwa udinga i-antenna ekhethiwe yomsakazo we-satellite.
Noma kunjalo, ukubonwa kwakho ukuthi awukaze ubone imoto ukushayela nxazonke nge-satellite dish kuyinto ehlakaniphile. Umsakazo wesathelayithi, ngokungafani nethelevishini ye-satellite, awusebenzisi izitsha. Isizathu esiyinhloko yi-bandwidth, kodwa kunengqondo ukusho ukuthi umsakazo we-satellite usebenzisa ama-antenna amancane, angaqondisi (afana namafoni amaningi we-satellite ongase ubone).
Okwenza Udinga I-Satellite Radio Antenna
Kokubili umsakazo womhlaba kanye nomsakazo we-satellites usebenzisa ama-antenna omnidirectional, okungaqhathaniswa nama-antenna aqondisayo asetshenziswa ngamasevisi athelevishini e-satellite. Kodwa-ke, i-antenna yakho yemoto ekhona eyenzelwe ukwamukela izimpawu ze-AM ne-FM ayikwazi ukuthola iziteshi zomsakazo we-satellite. Inkinga ukuthi i-FM yokusakaza i-FM iyingxenye yomsakazo we-VHF ophezulu kakhulu, i-AM band isebenzisa ingxenye yendima ye-frequency (MF), futhi umsakazo we-satellites uhlala kwi-S-band.
Nakuba kunezinhlobonhlobo ezincane phakathi kwamazwe ahlukene nezifunda, amaqembu aseNyakatho Melika yi:
AM umsakazo: 535 kHz kuya ku-1705 kHz
Umsakazo we-FM: 87.9 kuya ku-107.9 MHz
Umsakazo wesathelayithi : 2.31 kuya ku-2.36 GHz
Kungani I-Satellite Radio Engasebenzisi Izitsha
Okokuqala, kubalulekile ukuqonda ukuthi isitsha se-satellite empeleni nje uhlobo olukhethekile lwe-antenna. Zibizwa ngokuthi yi-antenna eziqondisayo ngoba zenzelwe ukwamukela izibonakaliso esakhiweni esivela ngaphandle emaphethelweni endle, yingakho kufanele uhlose isitsha se-satellite engxenyeni ethile yesibhakabhaka ukuze isebenze. Inzuzo eyinhloko yalolu hlobo lwe-antenna yukuthi iyakwazi ukuthola ulwazi oluningi kusuka kumsakazo obuthakathaka kunokuba i-antenna ye-omnidirectional izokwazi. Ngalolo hlobo olufanayo, ama-antenna angamaqondana angasetshenziswa ngempela ukuthola izimpawu ezibuthakathaka zethelevishini nezomsakazo ezindaweni ezikude , izibonakaliso ezikude ze- Wi-Fi , nezinye izinhlobo zezimpawu ezibuthakathaka noma ezikude.
Ukuthi kungani umsakazo we-satellite usebenzisa ama-antenna omnidirectional kanye nethelevishini ye-satellite isebenzisa izitsha, kwehle ngempela kunani lolwazi okufanele ludluliselwe ngezinsizakalo ezahlukene. Ukudluliswa komsindo kuthatha umkhawulokudonsa ongaphansi kunamathekisthi ethelevishini afaka kokubili ingxenye yomsindo nevidiyo. Ngakho ngenkathi abahlinzeki bethelevishini be-satellite bengase basebenzise ama-antenna omnidirectional, bebengeke bakwazi ukunikeza iziteshi eziningi kakhulu.
Ukufaka i-Satellite Radio Antenna
Njengoba ama-antenna e-satellite anemisindo e-omnidirectional, akudingeki ukhathazeke ngokukhomba kubo kunoma yisiphi isiqondiso esithile. Noma kunjalo, kubalulekile ukubeka i-antenna yomsakazo we-satellites ukuze ibe nombono ongenakulinganiswa wesibhakabhaka, futhi kubaluleke kakhulu ukukhetha indawo lapho ungayitholi khona ukuphazamiseka.
Uma ushayela imoto ngenhla eqinile, i-antenna kufanele ifakwe:
- eduze nangaphambili noma ngemuva kwephahla
- amasentimitha amathathu noma ngaphezulu kusuka emaphethelweni ophahleni
- amasentimitha amathathu noma ngaphezulu kude namanye ama-antenna
- endaweni ethile ukuthi i-rack roof (noma ezinye izinto ezifanayo) ngeke zivimbele isibhakabhaka
Uma ushayela i-convertible, kusobala ukuthi awukwazi ukuphakamisa i-antenna ye-satellite ophahleni. Uma kunjalo, uzofuna ukuyifaka:
- esitokisini esiseduze nesisekelo somoya
- kwi-hood eduze nomngcele ongemuva
- amasentimitha amathathu noma ngaphezulu kusuka emaphethelweni e-hood noma esihlahleni
Kunoma yikuphi, ungalokothi ufake i-antenna yomsakazo we-satellite:
- ngaphakathi kwemoto
- ngamasentimitha angaphansi kwamathathu avela kuma-antenna, ama-rack racks, nezinye izesekeli
- kwi-a, b, noma c insika
