Which of the following describes a G5RV antenna?
- A.A wire antenna center-fed through a specific length of open-wire line connected to a balun and coaxial feed line (correct answer)
- B.A multi-band trap antenna
- C.A phased array antenna consisting of multiple loops
- D.A wide band dipole using shorted coaxial cable for the radiating elements and fed with a 4:1 balun
WhyA G5RV antenna is a wire antenna center-fed through a specific length of open-wire line connected to a balun and coaxial feed line. A G5RV antenna is a wire antenna center-fed through a specific, carefully chosen length of open-wire transmission line, which then connects to a balun and ordinary coaxial feed line running the rest of the way to the shack, a design meant to work reasonably well across multiple HF bands, answer A. It isn't a trap antenna, isn't a phased loop array, and isn't built from shorted coaxial cable radiating elements, those describe different antenna designs entirely.
