80 - 10 Meter HF Antenna
Manufactured by My Radio OASIS
What separates this antenna from the rest out there?
The G5RV is an superb all-band (3.5-30 MHz) 102 Ft. dipole.
The 31.5 Ft. ladder line feeder of 450 ohms achieves a resonance on all bands
from 80 to 10 meters with only one antenna and without any loss in traps or coils.
The impedance at the end of the 450 ohm feed line is 50-60 ohms
which makes it perfect for a direct connect to standard 50 ohm coax.
Description of Operation
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 is two full-wavelengths in phase. In the 28 MHz band it operates as two one and a halfwave in line fed in phase.
The G5RV is slightly short on 80 meters where the 450 ohm line serves as a form of matching stub and both a stub and/or impedance matching transformer on the other bands.
