Mohala oa fatše o sebelisoa ho fana ka tsela ea hore motlakase o khutlele mohloling. Hangata e entsoe ka koporo, aluminium kapa lisebelisoa tse ling tse tsamaisang haholo.

Thebe ea tšepe e sebelisoa ho sireletsa mohala oa phetisetso ea insulated ho tšitiso ea motlakase. Hangata e entsoe ka aluminium kapa lisebelisoa tse ling tsa tšepe tse nang le matla a holimo.

Ha u khetha likarolo bakeng sa mohala o thata, ho bohlokoa ho nahana ka matla a ho sebetsa le a hona joale, maqhubu le mocheso. Ho feta moo, likaroloana li tlameha ho khethoa ho netefatsa hore lia lumellana, le hore mohala oa phetiso o fihlela litlhoko tse lakatsehang tsa motlakase le tsa mochini.
Ho na le mefuta e mekae ea mela e thata?
Ho na le mefuta e 'meli ea mela e thata: likhoele tsa coaxial le waveguides. Lithapo tsa coaxial li sebelisoa haholo ho tsamaisa mats'oao a motlakase a maqhubu a phahameng, ha li-waveguides li etselitsoe ho tsamaisa matla a motlakase ho maqhubu a seea-le-moea. Phapang e ka sehloohong pakeng tsa tse peli ke hore likhoele tsa coaxial li na le mokhanni oa ka hare o pota-potiloeng ke mokhanni oa ka ntle, ha li-waveguides li na le mochine o ka hare o pota-potiloeng ke thepa ea dielectric, e kang khalase kapa polasetiki. Ntle le moo, li-waveguides hangata li kholo ebile li ka nka matla a phahameng ho feta likhoele tsa coaxial.
Joang ho khetha mohala o thata ka ho fetisisa?
Ha u khetha mohala o thata ka ho fetisisa bakeng sa seteishene sa seea-le-moea se hasoang, ho bohlokoa ho nahana ka boemo ba matla le khafetsa ea seteishene, mofuta oa antenna le tikoloho ea lehae. Ho feta moo, ho bohlokoa ho hlahloba lintlha tsa moetsi bakeng sa mohala oa phetisetso le liwaranti tse teng, hammoho le lintlha tse akaretsang tsa litšenyehelo le ho kenya.
Joang ho hokahanya mohala o thata sebakeng sa phetiso?
Ho hokela mohala o thata seteisheneng sa seea-le-moea ka nepo, o lokela ho qala ka ho etsa bonnete ba hore mohala oa phetiso o thehiloe hantle. Ka mor'a moo, o lokela ho hokela mohala oa phetisetso tsamaisong ea manakana a seea-le-moea. U lokela hape ho hlahloba ho etsa bonnete ba hore mohala o tsamaisana hantle le sistimi ea antenna. Qetellong, o lokela ho hokela mohala oa phetisetso ho seholisa sa motlakase ebe o lokisa mochini o fetisang motlakase ho maqhubu a nepahetseng.
Litlhaloso tsa bohlokoa ka ho fetisisa tsa mohala o thata ke life?
Litlhaloso tsa bohlokoahali tsa 'mele le tsa RF tsa mohala o thata ke: impedance, bolelele ba motlakase, tahlehelo ea ho kenya, le tahlehelo ea ho khutla. Litšobotsi tse ling tse lokelang ho nahanoa li kenyelletsa tekanyo ea mocheso, sebaka sa mocheso, sebaka sa maqhubu a ts'ebetso, le tekanyo e phahameng ea voltage Stand wave ratio (VSWR).
Mokhoa oa ho boloka mohala o thata sebakeng sa phetiso?
Ho lokisa mohala o thata letsatsi le letsatsi seteisheneng sa seea-le-moea joalo ka moenjiniere, o lokela ho qala ka ho lekola mohala o thata ka mahlo ho bona matšoao leha e le afe a tšenyo, ho bola kapa ho senyeha. Hape u lokela ho etsa bonnete ba hore likhokahano tsohle li tiisitsoe hantle 'me li-clamp kaofela li sireletsehile. Ka mor'a ho hlahloba mohala, joale u lokela ho hlahloba mohala oa phetisetso bakeng sa liphetoho leha e le life ho li-parameter tsa motlakase tse kang matla a ho kenya, VSWR, le tahlehelo ea ho khutla. Qetellong, o lokela ho netefatsa sebopeho sa mahlaseli a antenna ho netefatsa hore e hokahane ka nepo le hore e sebetsa ka har'a litlhaloso.
Mokhoa oa ho lokisa mohala o thata haeba o sa sebetse?
1. Lekola mohala oa phetiso ho bona matšoao a tšenyo kapa a senyehile. Sheba hore na ha ho na likarolo tse robehileng kapa tse hlephileng, lithapo tse robehileng, kapa lihokelo tse kobehileng.

2. Kenya tse ncha sebakeng sa likarolo tse robehileng kapa tse tsofetseng. Etsa bonnete ba hore likarolo tse ncha li lekana ka boholo le sebōpeho joaloka tsa khale.

3. Hloekisa mohala oa phetisetso ka degreaser le lesela le bonolo.

4. Kopanya hape mohala oa phetisetso, ho netefatsa hore likarolo tsohle li tiisitsoe ka mokhoa o sireletsehileng.

5. Lekola mohala oa phetiso ho netefatsa hore o sebetsa ka nepo.

6. Haeba mohala oa phetisetso o hloleha ho sebetsa, hlahloba mathata leha e le afe a mang a mang a kang ho lutla ha moea kapa bokhutšoane moleng. Fetola likarolo tse ling tse eketsehileng ha ho hlokahala.
Ke mefuta efe ea lihokelo tse sebelisoang bakeng sa mohala o thata?
Mefuta ea lihokelo tse sebelisoang bakeng sa lithapo tsa phetisetso tse thata li kenyelletsa li-crimp-on le lihokelo tse rekisoang. Li-connectors tsa crimp-on hangata li entsoe ka koporo kapa aluminium 'me li hloka tšebeliso ea sesebelisoa sa crimping ho hatella sehokelo moleng. Lihokelo tse rekisoang hangata li entsoe ka koporo kapa thini mme li hloka tšepe ea solder le solder ho hokela sehokelo moleng. Ho na le mefuta e mengata e fapaneng ea likhokahano tsa crimp-on le tse rekisoang tse fumanehang, ho kenyeletsoa lihokelo tsa compression, lihokelo tsa twist-on, li-spade lugs le lihokelo tsa butt. Mofuta o mong le o mong o na le melemo le mefokolo ea oona e ikhethang. Palo ea mefuta ea mofuta o mong le o mong oa sehokelo e ipapisitse le ts'ebeliso e khethehileng le litlhoko.
