I konei, ka rukuhia e mātou ngā āhuatanga matua e tino whai hua ai te SMF. muka aratau-kotahi he kōwhiringa pai mō te tuku raraunga tere-teitei.
1. Te whānui o te matua:
He iti te diameter o te matua o te muka aratau-kotahi, tata ki te 8 ki te 10 maikiromita te nuinga. Mā tēnei matua iti ka taea te horapa kotahi anake te aratau mārama, ka whakaitihia te horapa o te momo raraunga, ā, ka taea te tuku raraunga ki ngā tawhiti roa me te kore e pakaru.DACion.
2. Te whakaiti iti:
Ko tētahi o ngā āhuatanga matua o te muka aratau-kotahi ko tōna tere whakaiti iti. Ko te whakaiti e pā ana ki te ngaronga o te kaha tohu i a ia e haere ana i roto i te muka.

3. Te whānui o te hononga:
He tino teitei ngā āheinga whānui o ngā muka aratau-kotahi. Ko te tikanga ka taea e rātou te tautoko i ngā tere raraunga teitei ake i ngā muka aratau-maha. He mea nui te whānui mō ngā tono e hiahia ana ki te tuku raraunga nui, pērā i ngā tuara ipurangi me ngā pokapū raraunga.
4. Tuku tawhiti:
Nā te iti o te whakaiti me te whānui o te hononga, he pai rawa ngā muka aratau-kotahi mō te tuku tawhiti. Ka taea e rātou te tuku tohu i ngā tawhiti neke atu i te 100 kiromita me te kore e hiahiatia he whakakaha tohu, he tukurua rānei, ā, he iti te utu mō ngā whakatinanatanga whatunga nui.
5. Hototahitanga o te roangaru:

6. Te iti rawa o te pokanoa:
Kāore e tino pāngia ngā muka aratau-kotahi e ngā pokanoa mai i ngā pūtake o waho, pērā i te pokanoa hikohiko (EMI) me te pokanoa auau reo irirangi (RFI). Mā tēnei ka ma ake, ka pono ake hoki te tohu, he mea nui mō ngā tono whakawhitiwhiti kōrero nui.
