Balun wire
웹1일 전 · The CCTV baluns are also known as UTP baluns and CAT5 baluns, and they allow CAT-5 cable and other twisted-pair wire to be used in CCTV camera and HD security camera installations. Using video baluns allow installers to use more cost-effective structured cabling techniques to wire security cameras instead of using traditional RG59 Siamese coax cable. 웹2024년 8월 17일 · Does a long wire antenna need a balun? There must be a current balun, not a voltage or unun one, in order for it to work. Strong common mode impedance and high voltage breakdown are required for a 1:1 ratio. Given its high SWR, the coaxial feed line should be high-quality and short.

웹2일 전 · Houd de afstand tussen de BalUn en de aanpassingstrafo zo kort mogelijk. In het geval dat er alleen een impedantie aanpassing moet worden gemaakt maar beide systemen zijn ongebalanceerd (asymmetrische) dan is alleen een aanpassingstrafo voldoende. Denk aan een ground plane antenne, end fed antenne of long wire antenne met 1:9 BalUn.
