Hōʻike Overview

No UHF kēia module ʻO nā lako kamaʻilio lekiō ma ke alapine, hiki ke hoʻouna i ka leo a me ka wikiō i loko o kahi palena palena. Hoʻolālā ʻia no ka hoʻohana haʻahaʻa haʻahaʻa, VCO hoʻohui, PLL, ame AM broadband demodulate wikiō, ʻO ke alapine o ka lawe leo e liʻiliʻi i ka module; lawe ʻo ia i kahi pūʻolo papa hoʻokahi, He mea maʻalahi ia no nā mea hoʻohana e hoʻoemi i nā noi.

Pono ka hoʻohana ʻana o kēia module e hoʻopili wale i ka lako mana, uwea leo, a me ka uwea wikiō, a hoʻohui i ka antenna e hoʻohana i nā ʻano mea uila uila e kākoʻo ana i ka hoʻokipa TV analog, me nā kelepona paʻalima, Nā TV, laptops, MP4, a me nā kiʻi kikohoʻe.

Hiki iā ʻoe ke hana i kēia mea hoʻolele wikiō uila UHF me kahi amplifier 10-watt?

I kēia manawa ʻaʻohe mea hoʻouna wikiō analog me kahi 10-watt PA. ʻAʻole wale ia e hoʻohui i kahi 10-watt PA i kā mākou transmitter wikiō analog. Pono e hoʻolālā hou a hana hou.

Manaʻo ka ʻenekinia e hoʻāʻo mua ʻoe i kā mākou transmitter wikiō analog maʻamau. Ma hope o kou hoʻohana ʻana, e haʻi mai iā mākou i ka mea e hoʻomaikaʻi ʻia a hiki iā mākou ke hoʻohui iā lākou i ka laʻana hou me kahi 10-watt PA. No laila makemake ʻoe e hoʻāʻo i kahi laʻana (ʻaʻohe PA) ka mua?
