Kodi VHF Slot Antenna ndi Chiyani Ndipo Imagwira Ntchito Motani?

VHF slot antenna ndi imodzi mwazofala kwambiri kuwulutsa tinyanga zopangidwira kufalitsa wailesi mu gulu la VHF. Imagwiritsidwa ntchito kwambiri pamapulogalamu owulutsa pa TV pamayendedwe pafupipafupi a 167-223 MHz. 

Mtengo VHF kagawo ka antenna ili ndi polarization yopingasa, mawonekedwe a radiation yopingasa ya omnidirectional, komanso mawonekedwe ocheperako oyimirira, omwe ndi oyenera kuwulutsa kwa digito ndi analogi.

Design

VHF slot antenna imapangidwa makamaka ndi ma radiation omwe amayikidwa muzitsulo zosapanga dzimbiri. 

Pakhomo la mlongoti ndi chimango chachitsulo chosapanga dzimbiri zimapanga thupi lalikulu la VHF slot antenna. Mphunoyo imapangidwa ndi aluminiyamu alloy, ndipo zinthu zinayi zowunikira zimapanga resonator yamakona anayi.

Popanga zotsekera, gulu lathu la mainjiniya lidaganizira mozama kumasulira kwa zero ndikupendekeka kwa mtengo: 

1. Kupendekeka kwa angle: 0.5 digiri
2. Kupeza kwa mlongoti: 11 dB
3. Radiation (Yopingasa): yozungulira.

Chitsulo chachitsulo chosapanga dzimbiri chili ndi ntchito zoikamo ndi kumangirira kuti zitsimikizire kukhazikika kwa ma radiation patsekeke, komanso zimakhala ndi ntchito za radiation ndi chitetezo cha kuwala. 

Popeza patsekeke lalikulu n'zosavuta kupunduka, zitsulo zosapanga dzimbiri chimango akhoza kuonetsetsa kuuma ndi kukhazikika kwa poizoniyu patsekeke. 

Chitsulo chosapanga dzimbiri chikhoza kukhazikitsidwa mwachindunji kumbali ya nsanja popanda kusintha mawonekedwe a patsekeke.

kapangidwe

Nthawi zambiri, mawonekedwe a VHF slot antenna ndiosavuta ndipo nthawi zambiri amakhala ndi izi:

• Chitsulo cholimbitsa
• Chophimba chachitetezo
• Zakudya zokhazikika
• bulaketi
• Lowetsani doko
• Mtundu wothandizira
• Thupi lalikulu la antenna
• Chophimba cha fiberglass

Zofunika

Pankhani ya zida, ma VHF slot antennas amapangidwa kuchokera kuzinthu zotsatirazi:

• Mkuwa wam'madzi
• Mkuwa
• zotayidwa
• Virgin Teflon

Muli Ndi Makina Athunthu a VHF Slot Antenna System?

Zotsatirazi ndizoyambira kwambiri VHF kagawo ndondomeko ya antenna zida:

1. Payokha kudyetsedwa VHF kagawo mlongoti
2. Malo otetezedwa (chivundikiro cha slot kapena chosindikizidwa cha radome)
3. Antenna coaxial cable (nthawi zambiri chingwe cha feeder, eg1-5/8'' coax)
4. Chingwe chophatikizira chowonjezera
5. Antenna Mounting Mast / Bracket

Mukufuna kudziwa zambiri? Chonde kambiranani ndi timu yathu yogulitsa!

Zachidziwikire, kuphatikiza pazida izi, pakukhazikitsa, muyenerabe kulabadira:

1. Malo oyika antenna. Mutha kukweza ma antennas athu a VHF pamwamba pa nsanja, m'mbali mwa nsanja, kapena mozondoka. Ngati atakwera pambali, ganizirani m'lifupi mwansanja kapena m'mimba mwake ya mast kuti mukhale ndi ma radiation abwino opingasa. Nthawi zambiri, mafunde a VHF ndiatali ndipo m'mimba mwake wa mast alibe mphamvu.
2. Kuti mupindule kwambiri. Ikani tinyanga ziwiri kapena zingapo molunjika. Kusankha koyenera kwa kutalika kwa mzere wosinthira mzere ndi coaxial feeder pakati pa node kumatha kuthetsa mavuto a zero-fill interpolation ndi kupendekeka kwa mtengo.
3. Kutalika kwapansi
4. Kutalika kwa antenna

FMUSER: Wopanga Kupindula Kwambiri kwa VHF Slot Antenna

FMUSER yapereka mazana a owulutsa pa TV padziko lonse lapansi mayankho a turnkey omwe amaphatikiza magwiridwe antchito ndi kusinthasintha, kuphatikiza zida zapamwamba za antenna slot, malangizo oyika pa intaneti, ntchito zomaliza zogulitsa, ndi zina zambiri. 

Tikuwonetsetsa kuti kagawo kanu Mlongoti ukhala wofanana ndendende ndi nsanja yanu yowulutsira ndipo ipitiliza kukutumikirani kwazaka zambiri pakuwulutsa kwambiri.

Mbali Zazikulu Zazinthu Zathu

• Gulu III (167-223 MHz)
• Njira yodalirika yopanga (yopangidwa kuchokera ku mkuwa, mkuwa, aluminiyamu, ndi namwali PTFE)
• Mapangidwe apamwamba (kukana dzimbiri, kukana mphepo, kukana kugwedezeka, etc.)
• Zowonjezera zina ndi zolandilidwa, chonde titumizireni kuti mumve zambiri (kugwiritsa ntchito mphamvu kwa antenna kokhazikika kumalola kuwonjezeka. Kupezeka mu mphamvu zamagetsi kuchokera ku 1kW mpaka 90kW, kumathandizira mopingasa, mozungulira, ndi elliptical polarization, azimuth ndi ma elevation modes, kupanikizika kapena osapanikizika. , etc.)
• Zabwino kwambiri Stand wave ratio.
• Standard Heavy null fill
• Njira zozungulira, zozungulira, kapena zozungulira zilipo.
• Ma azimuth okhazikika ndi mitundu yophatikizika mwachizolowezi ilipo.
• Ma radomu ang'onoang'ono komanso odzaza ndi mphepo yotsika (posankha)
• Kuwongolera pa intaneti (chonde tilankhule nafe ngati mukufuna chitsogozo patsamba)
• Mwaukadaulo wotsimikizika chigawo soldering
• Kuyesa chitetezo ndi magwiridwe antchito musanachoke kufakitale
• Zingwe za feeder ndi zida zina za mlongoti (ngati mukufuna)
