required to use coaxial cable with a dipole antenna. The balun transfers power between the single-ended coax and the balanced antenna, sometimes with...

The G5RV antenna is a dipole with a symmetric resonant feeder line, which serves as impedance matcher for a 50 Ω coax cable to the transceiver. Louis Varney...

mounted collinearly (in a line), fed in phase. The coaxial collinear (COCO) antenna uses transposed coaxial sections to produce in-phase half-wavelength radiators...

RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize...
