A wire antenna center-fed through a specific length of open-wire line connected to a balun and coaxial feed line✓Richtige Antwort
A multi-band trap antenna
A phased array antenna consisting of multiple loops
A wide band dipole using shorted coaxial cable for the radiating elements and fed with a 4:1 balun
Erklärung
The G5RV is a flat top about 102 feet long, fed at its center through a matching section of open-wire line — about 34 feet of 450-ohm line on the full-size version — which then connects to a balun and coaxial feed line. It contains no traps and no loops; the open-wire section is what makes it usable on several bands.
