Omnidirectional fiberglass Antenna 390-420MHz 5dBi
Chiyambi cha Zamalonda
Mlongoti uli ndi maulendo afupipafupi a 390-420MHz ndi kupindula kwa 5dBi, kuonetsetsa kuti ntchitoyo ikugwira bwino ntchito zosiyanasiyana.
Ma antennas athu amnidirectional fiberglass amapangidwa mochititsa chidwi 85%, kuonetsetsa kulumikizana kodalirika komanso kokhalitsa.Mulingo wake wa IP67 wosalowa madzi umatsimikizira kukana nyengo yoyipa, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito panja kulikonse.
Chimodzi mwazinthu zodziwika bwino za mlongoti wathu wa omnidirectional fiberglass ndi kuthekera kwake kutumiza ndi kulandira ma siginecha mbali zonse nthawi imodzi chifukwa cha kapangidwe kake kozungulira.Izi zimatsimikizira kufalikira kwakukulu komanso kugawa kwazizindikiro moyenera, kuchepetsa malo osawona komanso kupereka kulumikizana kosasinthika.
Antennas athu amnidirectional fiberglass antennas amapangidwa kuchokera ku zida zapamwamba kwambiri kuti zitsimikizire kulimba komanso kugwira ntchito kwanthawi yayitali ngakhale pazovuta kwambiri.Kumanga kwa fiberglass sikungowonjezera kulimba kwake, komanso kumapangitsa kuti ikhale yopepuka, yophweka kuyika ndi kukonza.
