The G5RV is an excellent all-band (3.5-30 MHz) 102 Ft. dipole. The 102 Ft. dipole with 31 Ft. feeder of 450 ohm transmission line achieves a resonance on all bands from 80 to 10 meters with only one antenna without any loss in traps and coils The impedance at the end of the 450 ohm feed line is 50-60 ohms.

 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.

 III. Installation

 The G5RV must be fed with a coax cable at least 70 Ft. long in order for the antenna to perform properly.

I. Introduction

The G5RV-M is an excellent all‑band (160-10 meter band) dipole. The 204 ft. Dipole with 64 ft. Feedline of 450 ohm transmission line achieves a resonance on all bands from 160 thru 10 meters with only one antenna without any loss in traps or coils. The impedance at the end of the 450 ohm feedline is approximately 50-60 ohms.

II. Description of operation

On 160 meters the electrical center of the antenna is at about 30 ft. Down the 450 ohm feedline. On other bands it functions on a multiple of wavelength principle.

The G5RV-M is slightly short on 160 meters where the 450 ohm feedline serves as a form of matching stub and/or impedance matching transformer on the other bands.

III. Installation

The G5RV-M should be fed with 140 ft. Of coax cable for maximum efficiency.

I.         Introduction

 G5RV JR is an excellent all-band (7.0 - 30MHz) 51 Ft. dipole. The 51 Ft. dipole with 17 Ft. feeder of 450 ohm transmission line achieves a resonance on all bands from 40 to 10 meters, with only one antenna without any loss in traps and coils. The impedance at the end of the 450 ohm feed line is approximately 50-60 ohms.

 II.              Description of Operation

 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.

 III.       Instructions

 The G5RV JR must be fed with a coax cable at least 35 feet long in order the antenna to perform satisfactorily.

The Multi-Bander is an excellent all-band (3.5-30 MHz except 10MHz) 102 Ft. dipole. The 102 Ft. dipole with 31 Ft. feeder of 300 ohm transmission line achieves a resonance on all bands from 80 to 10 meters, except 30 meters with only one antenna without any loss in traps and coils The impedance at the end of the 300 ohm feed line is 50-60 ohms, a good match for the transformer and new RG8x mini foam coax.
