Prime Focus Parabolic Antenna 8-18 GHz 35dB Typ.Gain RM-PFPA818-35

Prime Focus Parabolic Antenna ndiye mtundu wapamwamba kwambiri komanso wofunikira wa mlongoti wowunikira. Lili ndi zigawo ziwiri zazikulu: chowonetsera chitsulo chowoneka ngati paraboloid of revolution ndi chakudya (mwachitsanzo, nyanga ya nyanga) yomwe ili pamalo ake.

Kuchita kwake kumatengera mawonekedwe a geometric a parabola: mafunde ozungulira omwe amachokera pamalo owoneka bwino amawonetsedwa ndi mawonekedwe owoneka bwino ndipo amasinthidwa kukhala mtengo wowongolera kwambiri wandege kuti utumize. Mosiyana ndi zimenezi, panthawi yolandira, mafunde a zochitika zofanana kuchokera kumunda wakutali amawonekera ndikukhazikika pa chakudya pamalo okhazikika.

Ubwino waukulu wa mlongoti uwu ndi mawonekedwe ake osavuta, kupindula kwakukulu, kulunjika chakuthwa, komanso mtengo wotsika wopanga. Zoyipa zake zazikulu ndikutsekeka kwa mtengo waukulu ndi chakudya komanso mawonekedwe ake othandizira, zomwe zimachepetsa mphamvu ya tinyanga ndikukweza milingo ya lobe yam'mbali. Kuphatikiza apo, malo omwe chakudyacho chili kutsogolo kwa chowunikira chimatsogolera ku mizere yayitali ya chakudya komanso kukonza zovuta. Amagwiritsidwa ntchito kwambiri polumikizirana ndi ma satelayiti (mwachitsanzo, kulandirira kwa TV), zakuthambo wawayilesi, maulalo a microwave terrestrial, ndi makina a radar.
