Ukukhetha imitha yamandla e-RF efanele kubalulekile ezintweni zokuhlola, njengoba ukutholwa kwesignali ye-RF okunembile kubaluleke kakhulu kunoma yiluphi uhlelo lokusebenza. Ngakho-ke, kunoma yisiphi isiteshi somsakazo we-FM esifuna amandla e-RF anembe kakhudlwana nezilinganiso ze-VSWR, ungayikhetha kanjani imitha yamandla ye-RF engcono kakhulu? Kunezinto ezimbalwa okufanele uzikhumbule lapho ukhetha imitha yamandla e-RF, okuyizinhlobo, ububanzi be-freq, isibonisi, nekhwalithi yomkhiqizo. Qhubeka ufunda ukuze uthole okwengeziwe!

 

#1 Ukuqonda Izinhlobo

 

Uma ufuna ukuthenga imitha yamandla e-RF, kufanele uqale uqonde uhlobo lwayo. Amamitha kagesi e-RF angahlukaniswa ngokuyisisekelo abe amamitha kagesi e-RF asekelwe ekushiseni, izithonjana ezine-diode-powered, amamitha kagesi e-RF amunca, namamitha okudlula. Imitha yamandla e-RF esekelwe ekushiseni iyisinqumo esihle lapho wenza imisebenzi yokulinganisa edidiyelwe, futhi umtshina osebenza nge-diode uyinketho lapho kudingeka ukufundwa kwezinga eliyisisekelo noma imvelo yesikhashana. Yebo, udinga ukunaka ukuthi imitha yakho yamandla e-RF ifanele yini ukurekhoda amamethrikhi ahlukile njengamandla amaphakathi, amandla okushaya kwenhliziyo, noma amandla emvilophu aphezulu. Nakuba imitha yamandla ye-RF yokumuncwa ifaneleka ukuthola idatha yelabhorethri enembe kakhulu, imitha yamandla edlula i-RF ifanele imisebenzi yasenkambu.

 

#2 I-Frequency Range Nezindaba Zokunemba

 

Ukukhetha ibanga lefrikhwensi elilungile kubalulekile. Ibanga lefrikhwensi elincane liza nephutha elikhulu, isibonelo, uma usebenzisa isidluliseli se-FM esinamabanga asuka ku-88 kuya ku-108Mhz, imitha yamandla ye-RF engu-85-110Mhz iyisinqumo sakho esingcono kakhulu.

 

Uma uvamise ukusebenzisa imitha yamandla e-RF engu-1-200Mhz ukuze uthumele isidluliseli se-FM, khona-ke iphutha laso liyoba likhulu kakhulu kunemitha yamandla e-RF enobubanzi obuncane be-freq. Kungase kubangele izinkinga ezifana nokucaciswa okungalungile kokuphuma kwamandla okuhambisa kanye nothi lwe-VSWR.

 

#3 Yenza i-Commissiong ibe lula kakhulu nge-APP Monitoring

 

Ukukhetha imitha yamandla e-RF enokuqapha kwe-APP kungasiza ukonga isikhathi. Lolu hlobo lwemitha yamandla e-RF lunikeza isibonisi sedijithali nomsebenzi wokuqopha umugqa wesikhathi. Ukugxila ekuthumeleni isidlulisi kanye ne-antenna sekusele ukuthi ukwenze, asikho isidingo sokuqopha i-VSWR futhi udlulisele imininingwane yamandla encwadini! Uyazi ukuthi lokhu kusho ukuthini emsebenzini wakho.

 

#4 Ungalokothi Ushiye Ikhwalithi Yomkhiqizo Ngemuva. 

 

Imitha yamandla e-RF enekhwalithi ephezulu ivamise ukuba nempilo ende yesevisi - iphinde iqinisekise ukunemba kokuthunywa kwakho. Ukwengeza, umklamo omangelengele unikeza ukuvikeleka okukhulu ukukhulula amamitha kagesi kumabhampu kunqubo yezokuthutha neyokuthutha. Ngakho-ke, hlala uqaphela ikhwalithi ngaphambi kokufaka i-oda lemitha yamandla ye-RF. 

 

#5 I-Freq Selective noma iFreq Fixed Type

 

Kuyaphawuleka ukuthi amamitha kagesi e-RF angakhetha imvamisa noma alungiswe amafrikhwensi, umehluko omkhulu phakathi kwakho kokubili ukunemba kanye nenani.

 

Isibonelo, imitha yamandla e-RF ephathekayo esuka ku-Bird ingahlangabezana nezidingo zokuhlola zamarange amafrikhwensi ahlukene (afana no-450kHz-2.7GHz noma 50-100MHz, njll.) kanye nobubanzi bamandla (afana no-100mW-10kW) ngokusebenzisa amandla e-plug-in izingxenye.

 

Nokho, intengo yayo ingafinyelela ezinkulungwaneni zamaRandi. 

 

Kubasakazi abaningi, inani elichichimayo lokuthengisa, ububanzi befrikhwensi, kanye nobubanzi bamandla nakho akudingekile, ngingasho ukuthi imiphumela yokuhlolwa ingaphansi kokuchezuka okukhulu (ngisho noma ukunemba okufunwayo kungu-± 5%).

 

Uma kuqhathaniswa nebanga lefrikhwensi ebanzi yangaphambili kanye nobubanzi bamandla, imitha yamandla ye-RF ekhetha ifrequency inokunemba okuphezulu kokuhlolwa kwendawo futhi ngokuvamile ishibhile. 

 

Lolu hlobo lwemitha yamandla e-RF lukhethekile Isetshenziselwa ukuqapha ukuphuma kwamandla e-RF kanye nevelu ye-VSWR yebhendi yefrikhwensi ye-FM, nayo eyanele ukuhlangabezana nokutholwa kohlelo lokudlulisela kweziteshi zomsakazo eziningi ze-FM ezinamandla aphansi.
