He aha ka Batwing Antenna a pehea e hana ai?

 

ʻO ka hoʻolālā hoʻolālā o ka FMUSER VHF batwing antenna

 

ʻO ka antenna batwing, a i ʻole super turnstile antenna, he polarized (cross dipole, horizontal polarization) omnidirectional antenna me ke ʻano like me ka batwing a i ʻole ka bow tie, ka mea maʻamau i hoʻohana ʻia i ka hoʻolaha pāʻoihana VHF a me UHF.

 

Turnstile a me Super Turnstile

 

Ua loaʻa maoli ka antenna batwing mai kahi ʻano cross dipole i kapa ʻia he antenna turnstile.

 

ʻO kahi hiʻohiʻona o ka FMUSER VHF batwing antenna

 

ʻOiai ua hoʻohana ʻia ka mea hope ma nā hui VHF a me UHF (e pili ana i 30 MHz a 3 GHz) e like me ka mea mua, ʻoi aku ka nui o ka noi koa o ka mea hope, a ʻo ka mana radiation he 3dB haʻahaʻa ma mua o ka radiation kiʻekiʻe o ka hapalua hawewe dipole me ka mana like. 

 

Hoʻolālā ʻia ka antenna batwing e lanakila ai i kēia hemahema.

 

'ole

 

Hoʻokumu ʻia ka antenna batwing i ʻelua mau mea pā pālahalaha ʻano ʻēheu kū hoʻokahi. Hoʻokomo pinepine ʻia nā ʻāpana ʻelua o kēlā me kēia ʻēheu ʻēheu ma luna o ka mast maʻamau i kahi mokuʻāina o 90 ° perpendicular i kekahi. 

 

No laila, hiki i nā dipoles ʻelua o ka ʻēheu ʻēheu ʻēheu ke loaʻa i ke ʻano omnidirectional (ʻo kēlā me kēia māhele he 90 ° ʻokoʻa mai kēlā me kēia, a he ʻehā mau pae i ka huina, ʻo ia hoʻi 360 ° omnidirectional). 

 

ʻO nā hiʻohiʻona hoʻoheheʻe ʻana o 4 bays FMUSER VHF batwing antenna

 

No laila, hiki i kēia ʻano antenna ke hana i ka radiation polarization horizontal. Ke kūkulu pono ʻia (e laʻa, ka hoʻopaʻa ʻana i ke kūpaʻa), hiki i ia mau antenna ke loaʻa i kahi VSWR o 1.1: 1 a i ʻole ka liʻiliʻi ma mua o 30% o ka bandwidth a loaʻa ka nui o ka waiwai.

 

Noi mai no ka olelo

 

He aha ka ʻōnaehana Batwing Antenna piha?

 

Eia nā ʻāpana kumu o ka ʻōnaehana antenna batwing:

 

  • Batwing antenna cross element x2 (hānai kūʻokoʻa)
  • ʻO ka mea hoʻokaʻawale mana antenna
  • Laina Hoʻouna ʻoʻoleʻa (e laʻa me 3-1/8'' coax ʻoʻoleʻa)
  • Antenna kau ʻana kia
  • Pākuʻi pae

 

ʻOiaʻiʻo, ma kahi o kēia mau mea pono, pono ʻoe e hoʻolohe i:

 

  1. ʻO ke kiʻekiʻe o ka ʻāina maʻamau (HAAT).
  2. Kiʻekiʻe honua
  3. ʻO ke kiʻekiʻe e kau ana i nā Antenna

noi

 

Hiki iā ʻoe ke ʻike pinepine i nā kiʻi ma Google e ʻōlelo ana ua hoʻokomo ʻia nā antenna batwing he nui ma ke kia hoʻokahi, a ʻo kēlā me kēia antenna batwing e hoʻokaʻawale mau ʻia (ma kahi o hoʻokahi lōʻihi nalu). ʻO ke kumu o kēia e hoʻonui i ka loaʻa ʻana o ka pae. 

 

Ma waena o lākou, hoʻohana ʻia ka huaʻōlelo "bay" e kuhikuhi i kahi antenna batwing hoʻokahi. ʻO ka hui collinear i hoʻokumu ʻia e ka hoʻopaʻa ʻana i nā antenna ʻēheu cradle bat hiki ke hōʻemi i ka mana radiation keu (maʻamau i ke kuhikuhi axial) a hāʻawi i ka loaʻa kiʻekiʻe a me ka loaʻa kiʻekiʻe kiʻekiʻe, kahi e kūpono ai ka batwing antenna no ka hoʻolaha honua.

 

ʻO nā hiʻohiʻona hoʻohālikelike o ka FMUSER VHF batwing antenna

 

ʻO ka antenna batwing ka antenna i makemake ʻia no ka lekiō haʻahaʻa haʻahaʻa a me ke kīwī. ʻO kēia no ka mea hiki i ka mea dipole o ka antenna batwing ke hāʻawi i kahi bandwidth ākea no ka antenna. 

 

ʻO ka bandwidth broadband a me ka hana maikaʻi loa e hoʻonani ia no ka hoʻohana ʻana i nā mea hou ATV. He kūpono kēia ʻano no nā hui hoʻolaha e makemake ana e hoʻohana i hoʻokahi antenna e kōkua i nā mea hoʻouna he nui e hoʻouna i nā hōʻailona TV.

 

Noi mai no ka olelo

 

ʻOiai ʻo ka antenna batwing ka mea mua i hoʻohana nui ʻia i ka TV broadcast antenna, ma kahi o ke kamaʻilio VHF (FM, TV), hoʻohana pinepine ʻia ka antenna batwing i ka kamaʻilio pūʻali koa a me ke kamaʻilio ukali, ʻokoʻa ko lākou helehelena, ʻaʻole wau e lawe iā ʻoe i nā kikoʻī ke ʻole. makemake ʻoe iaʻu, e waiho i kāu leka a e haʻi mai iaʻu!

FMUSER: Loaʻa kiʻekiʻe VHF Batwing Antenna Manufacturer

 

Ma ke ʻano he mea hana ʻoihana a me ka mea hoʻolako i nā antenna hoʻolaha ʻēheu ʻēheu, ua hāʻawi ʻo FMUSER i nā hopena turnkey piha no nā haneli o nā lekiō a me nā kīwī a puni ka honua, me:

 

  • Nānā maikaʻi o ka huahana ma mua o ka hoʻouna ʻana
  • Hāʻawi ʻia i nā kaʻa he nui o nā antenna batwing a me nā kime
  • Kākoʻo pūnaewele no ka hoʻokomo ʻana a me ka wehe ʻana i nā antenna
  • ʻO ka lawelawe ma hope o ke kūʻai aku, etc. 

 

Hiki i kāu antenna batwing ke kū i nā makahiki he mau makahiki o ka makani, ka ua, ka hau, a me ka uila uila, a e lawelawe palekana a maikaʻi hoʻi i kāu mau kahua hoʻolaha no ka manawa lōʻihi.

  • Hoʻokipa ʻia nā mea hoʻohui ʻē aʻe, e ʻoluʻolu e kelepona mai iā mākou no nā mea hou aku (e laʻa me NTSC & CCIR channels, zero IMD, galvanized steel, beam tilt and null fill, Interbay lines, etc.)
