VHF Slot Antenna yog dab tsi thiab nws ua haujlwm li cas?

VHF qhov kav hlau txais xov yog ib qho ntawm feem ntau tshaj tawm antennas tsim los rau kev xa xov tooj cua hauv VHF band. Nws yog tsuas yog siv hauv TV tshaj tawm daim ntawv thov nyob rau hauv ntau zaus ntawm 167-223 MHz. 

Lub VHF qhov kav hlau txais xov muaj kab rov tav polarization, omnidirectional kab rov tav radiation qauv, thiab nqaim ntsug hluav taws xob qauv, uas yog heev haum rau digital thiab analog broadcasting.

tsim

VHF qhov kav hlau txais xov yog feem ntau yog tsim los ntawm cov kab hluav taws xob hluav taws xob tau teeb tsa hauv cov qauv hlau stainless. 

Lub kav hlau txais xov kab noj hniav thiab cov ncej stainless hlau ua lub cev tseem ceeb ntawm VHF qhov kav hlau txais xov. Cov kab noj hniav yog ua los ntawm aluminium alloy, thiab plaub lub ntsiab lus radiating tsim ib lub voj voog aluminium resonator.

Thaum tsim cov kab noj hniav, peb pab neeg engineering tau txiav txim siab xoom filling interpolation thiab beam qaij: 

1. Lub kaum sab xis: 0.5 degrees
2. Kav hlau txais xov nce: 11 dB
3. Radiation (kab rov tav): omnidirectional.

Stainless hlau thav duab muaj lub luag haujlwm ntawm kev teeb tsa thiab nrawm kom ruaj khov ntawm cov kab hluav taws xob hluav taws xob, thiab tseem muaj cov haujlwm ntawm hluav taws xob thiab kev tiv thaiv lub teeb. 

Txij li cov kab noj hniav loj yog qhov yooj yim rau deform, stainless hlau ncej tuaj yeem ua kom lub zog thiab ruaj khov ntawm cov kab noj hniav. 

Stainless hlau ncej tuaj yeem kho ncaj qha rau sab ntawm tus pej thuam yam tsis hloov cov kab noj hniav.

qauv

Feem ntau, cov qauv ntawm VHF qhov kav hlau txais xov yog qhov yooj yim thiab feem ntau muaj cov hauv qab no:

• Reinforcement hlau
• Kev tiv thaiv npog
• Rigid pub
• bracket
• Tswv yim chaw nres nkoj
• Txhawb nqa
• Kav hlau txais xov lub cev
• Fiberglass npog

Hais txog cov ntaub ntawv, peb lub VHF qhov kav hlau txais xov yog tsim los ntawm cov ntaub ntawv hauv qab no:

• Marine tooj dag
• Tooj
• Txhuas
• Virgin Teflon

Dab tsi muaj qhov ua tiav VHF qhov kav hlau txais xov?

Cov hauv qab no yog qhov yooj yim tshaj plaws VHF qhov kav hlau txais xov system Cheebtsam:

1. Kev ywj pheej pub VHF qhov kav hlau txais xov
2. Qhov kev tiv thaiv qhov (slot cover los yog kaw tag nrho radome)
3. Kav hlau txais xov coaxial cable (feem ntau feeder cable, eg1-5/8 '' coax)
4. Pressurized feeder cable
5. Kav hlau txais xov Mounting Mast / Bracket

Tau kawg, ntxiv rau cov cuab yeej no, thaum lub sijhawm teeb tsa, koj tseem yuav tsum tau them sai sai rau:

1. Antenna installation qhov chaw. Koj tuaj yeem mount peb VHF qhov kav hlau txais xov nyob rau sab saum toj ntawm tus pej thuam, ntawm sab ntawm tus pej thuam, lossis upside down. Yog mounted rau sab, xav txog ntauwd dav lossis mast txoj kab uas hla kom zoo kab rov tav hluav taws xob. Feem ntau, VHF wavelengths ntev dua thiab mast txoj kab uas hla tsis tshua muaj txiaj ntsig.
2. Rau kev pab ntau dua. Muab ob lossis ntau lub kav hlau txais xov vertically. Kev xaiv tsim nyog ntawm kev sib kis kab ntev ntawm kab converter thiab coaxial feeder ntawm nodes tuaj yeem daws cov teeb meem ntawm xoom-fill interpolation thiab beam qaij.
