Cassegrain Antenna 26.5-40GHz Frequency Range, Pezani 40dBi Typ.RM-CGA28-40

Mlongoti wa Cassegrain ndi mlongoti wowoneka bwino wapawiri, womwe dzina lake ndi kapangidwe kake zimachokera ku telesikopu ya Cassegrain. Zimapangidwa ndi chowonetsera choyambirira (paraboloid) ndi chowonetsera chachiwiri (hyperboloid), chomwe chili pamwamba pa malo owonetsera oyambirira.

Mfundo yake yogwiritsira ntchito ili motere: nyanga ya chakudya poyamba imatulutsa mafunde a electromagnetic kupita ku chowonetsera chachiwiri, chomwe chimawonetsera mafunde pa chowonetsera choyambirira. Chowunikira choyambirira chimawonjeza mafundewa kukhala mtengo wofanana, wolunjika kwambiri kuti utumize. Njira "yopindika" iyi imalola kuti chakudyacho chiyikidwe kuseri kwa chowunikira choyambirira, kuchepetsa kutayika kwa ma feedline ndikuchepetsa kukonza.

Ubwino waukulu wa mlongoti uwu ndi kupindula kwake kwakukulu, ma lobes otsika, mawonekedwe ophatikizika (poyerekeza ndi parabola yautali wautali), komanso kuyika kwa chakudya ndi zolandirira kumbuyo kwa chowunikira choyambirira, chomwe chimachepetsa kutaya kufalikira. Choyipa chake chachikulu ndikutsekeka kwa gawo la mtengo waukulu ndi chowunikira chachiwiri ndi mawonekedwe ake othandizira. Amagwiritsidwa ntchito kwambiri polumikizirana ndi ma satelayiti, zakuthambo zamawayilesi, ndi makina amtundu wautali wa radar.
