On 3.5 MHz, the electrical center of the antenna starts at approximately 15 Ft. down the 450 ohm line. On 3.5 MHz a portion of the dipole is operating as a folded dipole. The antenna functions as two half-waves in phase on 7 MHz with a portion folded in the center. In the 14 MHz band, the antenna operates as a three half-wavelength antenna. On 21 MHz the antenna acts as two full-wavelengths in phase. On the 28 MHz band it operates as two one and a half waves in line fed in phase.
G5RV is slightly short on 80 meters, where the 450 ohm line
serves as a matching stub and both a stub and/or
impedance matching transformer on the other bands.
To perform properly the G5RV should be fed with a coax cable at least 70 Ft. long..
