Nā, me pēhea te āwhina i te whakapai ake i te kaha o te tohu waea pūkoro? Ka whakamāramahia e mātou ngā mea e whai ake nei, ā, ka whakaaturia hoki ngā momo whakakaha waea pūkoro e wātea ana. Ko te whakakaha whiwhinga waea he pūnaha tukurua kei roto ko ngā whakakaha e whakanui ana i te whiwhinga, i te mana rānei ki te whiwhinga i ngā taha katoa. Ahakoa mō ngā whakakaha tohu waea pūkoro iti te utu, ka rerekē te whiwhinga mōrahi mai i te tono ki te tono. Ko te pūihi o waho hei whiwhi me te tuku tohu ki te pourewa pūtau me te kaha me te aro nui ake. Ko te nuinga o te wā, kāore te pikinga dB e iti iho i te 7db, ā, ka taea te neke atu i te pikinga 10db. Ko ngā taura coaxial ngā wāhanga o te pūnaha. He take anō hoki tēnei mō te ngaronga o te tuku.
Ko te whakamahinga matua o te whakakaha tohu waea pūkoro he whakakaha i te tohu waea pūkoro kei roto i te motuka, i te tari, i te teihana mahi, i te kāinga rānei. Kia whakakahangia te tohu, ka tukuna anō te tohu ki te wāhi kāore he tohu, he ngoikore rānei e whiwhihia ana.
Haunga ngā whakakaha oro, ngā pūihi, me ngā pūihi e whakarei ake ana i te whiwhinga oro, kei reira anō ngā whakakaha waea pūkoro e whakauru ana i ngā pūihi me ngā whakakaha oro o roto, e pai ai mō roto.ngā kaiwhakakaha tohu waea pūkoro.
I te nuinga o te wā, he motuhake ēnei wāhanga e toru. Ko ētahi atu wāhanga kōwhiringa ko ngā attenuator (hei whakaiti i ngā tohu auau kāore e hiahiatia), ngā parenga hiko, ngā whakahurihuri, me ngā taputapu.
Tuarua, he aha te whakakaha tohu atamai? I te nuinga o te wā, ka tautuhia e tēnei he momo whakakaha tohu waea pūkoro ahokore hou e whakamahi ana i tētahi tukatuka turanga-matihiko kaha rawa atu hei whakakore i te kapinga i roto i ngā tukurua. Ko te whakanui o ngā whakakaha he 63-70dB, ā, mengā pūihi o waho. 
Tuatoru, te take o te ngoikore o te tohu? 1. Te tawhiti i waenganui i te pourewa pūtau me tō waka/kāinga:
Ko tētahi o ngā take mō te korenga o te whiwhinga waea pūkoro ko te tawhiti pea mai i tō pourewa waea pūkoro tata. Ka tata atu koe ki te pourewa waea pūkoro, ka kaha ake te tohu ka whiwhi koe. I tētahi atu taha, ka tawhiti atu koe i te pourewa waea pūkoro o tō kaikawe, ka kino ake te tohu o tō waea pūkoro.
2. Te pokanoa mai i waho:
Tērā pea ka pāngia te kapinga o tō waea e te pokanoa o waho. Kia mōhio koe ko ngā tohu waea pūkoro he ngaru reo irirangi, ā, ka taea te ārai ina haere tawhiti ki te tae atu ki tō waea. Me mārama te rārangi ki te pourewa kawe i te horapa o ngā ngaru. Heoi, ko ngā mea whakararuraru o waho, pērā i ngā maunga, ngā rākau, ngā whare teitei me ētahi atu puke whare teitei, ngā papa pānuitanga, ngā whatitiri hukarere me te ua, ka whakaiti i te hihiri. 
3. Te pokanoa mai i roto i te whare:
Ngā rauemi hanga matotoru, pērā i te pereki me ngā paparanga raima matotoru, ngā ārai irahiko, te karāhe me te konganuku, te paru hikohiko me te hiko iti, me ngā rauemi kawe hiko e aukati ana, e whakaiti ana rānei i te paparanga tiaki e tomo mai ana. Tērā pea he tino pai tō tohu o waho, ahakoa he tata rawa ki tō rua pī kawe, engari i roto i tō whare, tērā pea he tino ngoikore te tohu nā te pokanoa o roto.
