Chii chinonzi VHF Slot Antenna uye Inoshanda Sei?

Iyo VHF slot antenna ndeimwe yeakajairika nhepfenyuro antennas yakagadzirirwa kutapurirana redhiyo muVHF bhendi. Inonyanya kushandiswa muTV kutepfenyura maapplication mune frequency renji ye167-223 MHz. 

Iye VHF slot antenna ine horizontal polarization, omnidirectional yakatwasuka mwaranzi pateni, uye nhete yakatwasuka mwaranzi pateni, iyo yakakodzera kwazvo kutepfenyura kwedhijitari neanalogi.

patani

Iyo VHF slot antenna inonyanya kuumbwa neradiation cavity yakaiswa musimbi isina tsvina chimiro. 

Iyo antenna mhango uye simbi isina tsvina inoumba muviri mukuru weVHF slot antenna. Iyo mhango inogadzirwa nealuminium alloy, uye zvinhu zvina zvinopenya zvinoumba rectangular aluminium resonator.

Kana tichigadzira mhango, timu yedu yeinjiniya yakanyatso funga zero yekuzadza kududzira uye kurerekera danda: 

1. Tilt angle: 0.5 madhigirii
2. Antenna kuwana: 11 dB
3. Radiation (Horizontal): omnidirectional.

Iyo simbi isina tsvina furemu ine mabasa ekuisa uye kusungirira kuve nechokwadi kugadzikana kweiyo radiation cavity, uye zvakare ine mabasa eradiation uye mwenje kudzivirira. 

Sezvo mhango hombe iri nyore kukanganisa, simbi isina tsvina inogona kuve nechokwadi chekuoma uye kugadzikana kweiyo radiation cavity. 

Iyo simbi isina tsvina inogona kugadziriswa zvakananga padivi peshongwe pasina kushandura chimiro chegomba.

mamiriro

Kazhinji, chimiro cheVHF slot antenna chiri nyore uye chinowanzo kuve nezvinhu zvinotevera:

• Simbi yekusimbisa
• Kudzivirirwa kavha
• Rigid feed
• Bracket
• Input chiteshi
• Tsigiro furemu
• Antenna huru muviri
• Fiberglass chivharo

zvinhu

Panyaya yezvigadzirwa, yedu VHF slot antennas inogadzirwa kubva kune zvinotevera zvinhu:

• Marine ndarira
• mhangura
• aruminiyamu
• Mhandara Teflon

Chii Chinosanganisira Yakazara VHF Slot Antenna System?

Aya anotevera ndiwo akanyanya kukosha VHF slot antenna system zvikamu:

1. Yakazvimirira yakadyiswa VHF slot antenna
2. Iyo yekudzivirira slot (slot chivharo kana chisimbiso chakazara radome)
3. Antenna coaxial tambo (kazhinji feeder tambo, eg1-5/8'' coax)
4. Pressurized feeder cable
5. Antenna Mounting Mast / Bracket

Ehe, mukuwedzera kune iyi midziyo, panguva yekuisa maitiro, iwe uchiri kufanira kutarisisa kune:

1. Nzvimbo yekuisa antenna. Iwe unogona kukwira yedu VHF slot antennas kungave pamusoro peshongwe, padivi peshongwe, kana kumusoro pasi. Kana akaiswa padivi, funga shongwe hupamhi kana dhayamita yemastadhi kune yakanaka yakachinjika mwaranzi. Kazhinji, VHF wavelengths yakareba uye mast diameter haina mhedzisiro.
2. Kuti ubatsirwe zvakanyanya. Rongedza maantenna maviri kana anopfuura akatwasuka. Kusarudzwa kunonzwisisika kwekureba kwemutsara weiyo inoshandura mutsara uye coaxial feeder pakati pemanodhi inogona kugadzirisa zvirinani matambudziko e-zero-zadza interpolation uye beam tilt.
3. Ground urefu
4. Antenna yekuisa urefu

FMUSER: Yakakwira Kuwana VHF Slot Antenna Mugadziri

FMUSER yakapa mazana evatepfenyuri veTV kutenderera pasirese nemhinduro dzeturnkey dzinosanganisa kuita uye kuchinjika, kusanganisira emhando yepamusoro slot antenna kits, online yekumisikidza mirairo, yakazara mushure mekutengesa sevhisi, nezvimwe. 

Isu tinova nechokwadi chekuti slot yako Iyo antenna ichanyatso kufananidzwa neshongwe yako yekutepfenyura uye icharamba ichikushandira iwe kwemakumi emakore pakunyanya kutepfenyura kuita.
