Mena kua whakamahia e koe te whakawhitiwhiti kōrero RF (auau reo irirangi), ngā whatunga waea pūkoro, ngā pūnaha pūihi rānei, tera pea ka tūtaki koe ki te kupu taura LMR. Engari he aha tonu tēnei, ā, he aha i whānuitia ai te whakamahinga? I roto i tēnei tuhinga, ka tūhuratia e mātou he aha te taura LMR, ōna āhuatanga matua, me te take he pai ake ai mō ngā tono RF, ā, ka whakautua te pātai 'He aha te taura LMR?'.
Kia mārama ki te taura coaxial LMR
He taura honohono te taura LMR i hangaia mō te tuku tohu mahi-teitei, iti te ngaronga i roto i ngā tono RF. Nā Times Microwave Systems i hanga ngā taura LMR, ā, e mōhiotia ana mō ō rātou parenga pai, iti te ngaronga tohu, me te roa, he mea pai mō te whakawhitiwhiti ahokore GPS. He kōwhiringa pai mō te radar me ētahi atu pūnaha RF. He rerekē ki ngā taura honohono tuku iho, he maha ngā paparanga o te parenga me ngā rauemi dielectric kua hangaia ngā taura LMR hei whakarite kia pai ake te pono o te tohu. He maha ngā rahi hei whiriwhiri māu, pērā i te LMR-195, LMR-240, LMR-400, me te LMR-600, ia taura i hangaia mō ngā whakaritenga tukatuka mana me te ngaronga tohu rerekē.
Ngā āhuatanga matua o te taura coaxial LMR
He mea motuhake ngā taura LMR i roto i te ao o ngā taura coaxial nā ō rātou hanganga ahurei me ngā painga mahi:
1. He iti te ngaronga tohu
Ko tētahi o ngā painga nui o ngā taura LMR he iti te ngaronga tohu ko tōna iti o te whakaiti i ngā tawhiti roa (ngaronga tohu). Ka tutuki tēnei mā te whakamarumaru me te ārai hiko kounga teitei, e whakaiti ana i te ngaronga pūngao ina haere ngā tohu mā roto i ngā taura.
2. He mahi tiaki pai rawa atu
He maha ngā paparanga parepare o te hoahoa taura LMR, tae atu ki te parepare rīpene konumohe hei tiaki i te EMI (whakararuraru hikohiko) tuatahi. Mā te whatu parepare o waho ka roa ake te mau, ā, ka whakaitihia anō hoki te whakararuraru. Mā tēnei parepare ka kaha ake, ka mārama ake hoki ngā tohu, ā, ka pai rawa atu ngā taura LMR mō ngā tono RF tairongo.
3. Te pakari me te ātete ki te huarere
Ka hangaia e Times Microwave Systems ngā taura LMR, ko tōna anga o waho he mea hanga ki te polyethylene (PE) me te thermoplastic elastomer (TPE), ā, ka ātete ki te hihi ultraviolet, te makuku, me ngā pāmahana tino kino. Ko ētahi momo, pērā i te LMR-UF (Ultra Flex), ka whakarato i te ngāwari tāpiri mō ngā tāutanga e hiahia ana kia piko me te nekeneke haere tonu.
4. Tāutanga ngāwari me te watea
Ki te whakatauritea ki ngā taura coaxial mārō tuku iho, he tino ngāwari, he mama hoki ngā taura LMR, ā, he māmā ake te tāutanga. He iti ake te whānui piko o ngā taura RF rite, ā, ka taea te tāuta piri ki ngā wāhi kua kati.
5. Hototahi ki ngā hononga RF
Ka tautokohia e ngā taura LMR ngā hononga maha, tae atu ki ngā hononga momo-N (e whakamahia whānuitia ana i roto i ngā tono pūihi me te RF). Hononga SMA (mō ngā pūnaha ahokore me te GPS). Hononga BNC (rongonui i roto i te pāpāho me te whatunga). Nā tēnei hototahi ka tino whai hua rātou i roto i ngā momo ahumahi.
Ngā Whakamahinga Noa o ngā Taura LMR
Nā te tino pai o te mahi, e whakamahia whānuitia ana ngā taura LMR i roto i ngā ahumahi e whakawhirinaki ana ki te whakawhitiwhiti kōrero RF. Ko ētahi o ngā tono tino noa ko ngā whatunga ahokore me te waea pūkoro, ngā pūnaha pūihi me te RF, ngā whakawhitiwhiti kōrero GPS me te amiorangi, ngā tono rererangi, ngā pūnaha aroturuki me te haumarutanga.
Kōwhiria te taura LMR tika
Ko te kōwhiringa o te momo taura LMR tika e whakawhirinaki ana ki ētahi āhuatanga, tae atu ki te auau, te tawhiti, te whakahaere hiko, me ngā āhuatanga taiao. Anei ētahi kōwhiringa noa:
LMR-195 me te LMR-240: He pai mō ngā tono tawhiti-poto pērā i ngā pūihi Wi-Fi me ngā pūnaha GPS.
LMR-400: He kōwhiringa reo irirangi waenga-whānui iti te ngaronga e whakamahia whānuitia ana i roto i ngā pūnaha reo irirangi pūkoro me ngā pūnaha reo irirangi rua-ara.
LMR-600: He tino pai mō ngā tono tawhiti e tika ana kia tino whakaitihia te ngaronga tohu.
Mena kei te hiahia koe ki te ngāwari o ngā taupānga pūkoro, he kōwhiringa pai anō hoki te taura LMR-UF (Ultra Flex).
