Nānā 1: ʻO ka mana hoʻopuka pūnaewele he hana ia o ka helu o nā mea lawe i ka ʻōnaehana, ka pae hōʻailona o kēia mau mea lawe i ka
ʻōnaehana hoʻonui hōʻailona, loaʻa nā PA, a me ka nalowale o ka hoʻokomo ʻana i nā kānana i loko o ka ʻōnaehana bidirectional.
Nānā 2: Pūnaehana Noise Figure ka huina o ka amplifier NF a me nā poho kānana ma mua o ka amplifier.ʻO nā poho o ka kānana e hilinaʻi ʻia ma
ka laula passband no na alapine uplink, ka laula passband no na alapine downlink, a me ka band hooki mawaena o lakou.
Hāʻawi ka loaʻa ʻana o kahi VHF Repeater BDA i ka ʻōnaehana kamaʻilio intercom me ka nui o ka noho ʻana o ke kahawai kiʻekiʻe, ʻoiai ua hoʻonui ʻia ka uhi ma mua o ka uhi ʻana o ka pūnaewele.ʻO nā noi maʻamau o kēia laina o nā booters he mau kūlana i loko e like me nā tunnels, nā hale, nā subways, a me nā hiʻohiʻona waho e like me nā kahua pāʻani, nā wahi kuaʻāina a me nā wahi kaona.No ka mea he ʻōnaehana ʻelua o nā lako, no laila hiki iā ʻoe ke mālama i ke kumukūʻai o ka pālua ʻana i ka mea hānai.
