ʻO kahi RF Dummy Load kahi mea i hoʻohana ʻia e hoʻohālikelike i kahi ukana uila i ka wā hoʻāʻo. Hiki iā ia ke hoʻāʻo i kāu lako RF me ka ʻole o ka hoʻopili ʻana i nā nalu radio.

Inā ʻoe i ʻike ma ke kahua o RF a ʻaʻole paha, pono ʻoe i kahi ukana dummy RF no ka hoʻāʻo ʻana i nā lako RF no ka hōʻoia ʻana i ka hana maʻamau o ka lekiō. Akā ʻike ʻoe pehea e ʻike ai i ka ukana dummy RF maikaʻi loa i ka wā e kū ana i nā koho like ʻole i ka mākeke?

No ke kōkua ʻana iā ʻoe e kūʻai i kahi ukana dummy RF kūpono a haʻahaʻa, hōʻike mākou i 6 mau mea nui e noʻonoʻo ai. E hoʻomaka kākou!

1 # Mana Mana

Ke hoʻāʻo nei ʻoe i ka lako RF, e loaʻa iā ʻoe ka ukana dummy RF e holo mau ana. No ka hana ʻana me ka palekana, no laila, pono ʻoe e noʻonoʻo inā ʻoluʻolu ka mana mana me kāu mau pono ma mua o ka mana kiʻekiʻe.

ʻO ka maʻamau, ʻōlelo ʻia ʻo ka haʻahaʻa haʻahaʻa RF dummy haʻahaʻa (ma lalo o 200w) no nā lekiō amateur a me nā lekiō haʻahaʻa haʻahaʻa ʻoiai ʻo ka mana kiʻekiʻe RF dummy ukana no nā lekiō ʻoihana.

2# Lahui alapine

Pono ʻoe e noʻonoʻo inā pili ka laulā alapine i kāu mau pono. ʻO ka mea maʻamau, loaʻa i kahi haʻahaʻa RF dummy kahi alapine ākea e like me DC (ʻo ia ka 0) a 2GHz, no laila ʻaʻole pono ʻoe e hopohopo nui iā ia. 

3 # Nā Waiwai Impedance

E like me nā ʻōnaehana antenna, pono ke hoʻokūkū maikaʻi ka RF dummy load me nā kumu RF pū kekahi. No laila, ʻo ka waiwai dummy load impedance e like me ka antenna a i ʻole ka laina hoʻouna.

ʻO ka RF dummy load 50 Ohm a me 75 Ohm nā ʻano maʻamau a mākou e hoʻohana ai. A ʻo ka RF dummy load 50 Ohm e kūlike me nā kumu RF maikaʻi loa i nā kūlana RF.

4 # Pūnaehana Hoʻopau Wela

ʻO ke kumu o ka ukana RF dummy e hoʻololi i ka antenna a loaʻa ka ikehu RF. E hoʻololi ʻia ka ikehu i hoʻopaʻa ʻia i wela i ka haʻahaʻa dummy, no laila, pono ʻoe e hoʻolohe i ka ʻōnaehana hoʻopau wela.

ʻO ka mea maʻamau, ke hilinaʻi nei ka ukana dummy i nā heatsinks, a ua hana ʻia lākou mai ka alloy, alumini, a me nā mea ʻē aʻe, a ua kapa ʻia kēia ʻano haʻahaʻa dummy load heatsink maloʻo. Ma waho aʻe o ka ʻōnaehana dissipation ma luna, aia kekahi mau ukana dummy RF e hoʻopau ana i ka wela e ka wai, me ka wai, ka aila a me ka ea, etc. 

Wahi a kā mākou ʻenekini Jimmy, ʻo ka hoʻoluʻu wai ke ala maikaʻi loa e hoʻopau ai i ka wela akā pono ia i ka mālama paʻakikī.

5 # Nā ʻano mea hoʻohui

ʻO ka hoʻohui ʻana i nā kumu RF me ka ukana dummy RF ʻo ia ka hana hope loa i ka hoʻomākaukau. ʻO nā mea a pau āu e hana ai, ʻo ia ka hōʻoia ʻana o ka mea hoʻohui. 

ʻO ka RF dummy load he ʻano ākea o nā ʻano mea hoʻohui, me ke ʻano N, ʻano BNC, a me nā mea ʻē aʻe.

Panina

Ma ke kamaʻilio ʻana, ua lako ʻoe i ka ʻike e kiʻi i ka ukana dummy RF maikaʻi loa. ʻO ka ukana dummy RF maikaʻi ka mea maʻamau i ke kūkulu ʻana i ka lekiō. 

Inā makemake ʻoe i kōkua hou aʻe i ke kūkulu ʻana i kāu lekiō, no ke aha e ʻimi ʻole ai i kahi hōʻailona hilinaʻi no ke kōkua? No ka laʻana, ʻaʻole hiki iā FMUSER ke hāʻawi wale iā ʻoe i nā ukana dummy RF me ka nui o nā mana mana mai 1W a 20KW, i lako me nā ʻano mea hoʻohui like ʻole a me nā ʻano hana hoʻoheheʻe wela e hoʻokō i kāu mau pono like ʻole.

Inā makemake ʻoe e pili ana i ka ukana dummy RF, e ʻoluʻolu e kelepona mai iā mākou!
