Coaxial Chingwe - kudalirika pa mtengo angakwanitse

Pakuti masiku zambiri anthu ndi uphungu wofunika kwambiri msika ndi zinthu zosiyanasiyana, kuonetsetsa chilengedwe cha apamwamba ndi odalirika media nkhani kulankhulana. Mmodzi wa iwo ndi chingwe coaxial. Iye anagwira ntchito bwino pamene ntchito zosiyanasiyana zolinga.

Coaxial chingwe digito chimagwiritsidwa ntchito zosiyanasiyana za zochita za anthu. Kwenikweni, ntchito popereka chizindikiro Kanema ndi makamera kanema. Ichi ndi chifukwa chakuti iwo oyenereradi popereka mkulu-pafupipafupi nyemba. kamangidwe kake wapadera amalola kukwaniritsa wapamwamba kwambiri yobereka chizindikiro chilichonse popanda imfa. Pankhaniyi, otaya zambiri zikhoza opatsirana pa mtunda wautali ndi attenuation pang'ono kapena ayi.

Nthawi zambiri, chingwe coaxial ali kapangidwe zotsatirazi: umene uli pakati pa wochititsa ndi (linakhazikitsidwa, kawirikawiri mkuwa) aikidwa mu mkulu osalimba polyethylene kumulowetsa ndi katundu dielectric ndipo aposa nsalu mauna a mawaya woonda zitsulo. Kuchokera pamwamba aphimbidwa ndi Manga chimateteza wa polyethylene kapena polyvinyl mankhwala enaake.

Coaxial chingwe, monga ena kufala thupi sing'anga, angapo a makhalidwe enieni. Choncho ndikofunikira kuchokera pachiyambi bwino kudziwa cholinga chotani, zimene chilengedwe adzakhululukidwa ntchito, kenako okha kusankha mtundu wa makhalidwe abwino kwambiri.

Mwachitsanzo, chingwe coaxial kwa kanema anaziika ayenera katundu zotsatirazi:

1. Iwo akhoza anatumiza ngati kuli kotheka kwa pafupipafupi sipekitiramu.
2. Osachepera chikoka pa chiphaso dera lotsatira kudzera zomwe magetsi imafalikira.
3. N'zotheka kukaniza apamwamba zinthu kunja.
4. Chitetezo kusokonezedwa.

Chinthu chofunika kwambiri ndi kukana kwa phokoso otsika-pafupipafupi, chifukwa uwu ndi drawback yaikulu ya mankhwala amenewa - ndi atengeke chizindikiro opatsirana pa mafurikwense otsika.

Coaxial chingwe ambiri amangoti ntchito ukuthamana pakati kulandiridwa ndi zipangizo kupatsira. Iye ndi imodzi mwa njira ambiri kupatsira chizindikiro TV ndi kanema. kuwanda ake si osachepera chifukwa cheapness wachibale.

Pali chiwerengero mwachilungamo lalikulu osiyanasiyana zingwe coaxial. Chachikulu kusiyana lagona makhalidwe thupi. Pa nthawi yomweyo Dziwani kuti mfundo ya kanthu pa mitundu yosiyanasiyana ya mankhwala chomwecho.

Ngati inu kusankha kukhazikitsa kulikonse (kunyumba kapena ofesi) dongosolo kanema anaziika, zotsogola kwambiri kufala sing'anga zidzakhala ndendende coaxial chingwe. Mudzalandira wodalirika dongosolo ntchito mu mlingo wochepa wa ndalama. Ndi kufalikira ndi nambala ya nsembe pa msika amakulolani kusankha mankhwala adzayenerera ndendende ndi zofuna zanu payekha. Zimenezi zingakuthandizeni kugwiritsa dongosolo la Kuvuta aliyense ndi nthambi.
