ʻO ke alapine lekiō i kapa ʻia ʻo RF, ʻo ka lekiō ʻo RF i kēia manawa, ʻo ia ke ʻano o ka hawewe electromagnetic kiʻekiʻe-frequency AC no ka pōkole. Loaʻa iā BTF Testing Lab kahi keʻena hoʻokolohua lekiō piha. ʻO ke ala ʻē aʻe e loli ana ma lalo o 1000 mau manawa i kēlā me kēia kekona, ua kapa ʻia ke ʻano haʻahaʻa, a ʻo ke alapine e ʻoi aku ka nui ma mua o 10,000 mau manawa i kapa ʻia ʻo ke alapine kiʻekiʻe, a ʻo ke alapine o ka lekiō he ʻano alapine kiʻekiʻe. Ke hoʻohana nei ka ʻōnaehana kelepona i ke ʻano hoʻoili uila.

I loko o ka uila, kahe ka uwila i loko o kahi mea hoʻokele a hoʻokumu ʻia kahi māla magnetic a puni ia. Ke hele nei ke au i loko o kahi conductor, a ua hoʻokumu ʻia kahi māla electromagnetic ʻokoʻa a puni ka conductor, i kapa ʻia he hawewe electromagnetic.

I ka haʻahaʻa ʻana o ka hawewe electromagnetic ma mua o 100kHz, e hoʻopili ʻia ka nalu electromagnetic e ka ʻili a ʻaʻole hiki ke hana i kahi hoʻoili kūpono, akā inā ʻoi aku ka kiʻekiʻe o ka hawewe electromagnetic ma mua o 100kHz, hiki i ka hawewe electromagnetic ke pālahalaha i ka lewa a hōʻike ʻia e ka ʻO ka ionosphere ma ka ʻaoʻao o waho o ka lewa, e hana ana i kahi hiki ke hoʻouna i kahi mamao lōʻihi, kapa mākou i ka hawewe electromagnetic kiʻekiʻe me ka hiki ke hoʻouna lōʻihi i ka radio frequency, ka pōkole English: RF
