G5RV Mutli-Band Antenna
INSTALLATION & USE
1. The G5RV Antenna requires no additional soldering or assembly. The antenna is completely
assembled, and ready to hang right out of the package.
2. Due to the multiband nature of a G5RV, an antenna tuner is recommended for proper SWR
tuning.
3. Ideally the center insulator should be supported and hung as high as possible, optimally a
minimum of 16’ for the 40m, 31’ for the 80M, and 62’ for the 160M version, above the
ground.
4. Attach rope to each of the end insulators of the antenna and suspend from appropriate tree or
other structure. Allow a slight amount of sag if attaching to trees to allow for wind swaying.
5. Both radiating elements should be hung horizontally under ideal conditions, however they can
be installed as a semi-inverted-V as long as the total angle between both elements stays greater
than 170º
6. The matching section (window-line) should descend at a right angle to the radiating elements.
7. A
MINIMUM
of 70 feet of 50Ω coaxial feedline is
REQUIRED
to be used between the vertical
balanced window line and your HF radio / antenna tuner. This antenna design does not use
expensive baluns for matching. The coaxial feedline works in conjunction with the balanced
window line to form the matching network. This long standing, highly regarded antenna design
is not only less expensive, but also more forgiving in less-than-ideal installation environments
than Windoms or other off-center fed dipoles.
8. Adequately weatherproof the coaxial connection with Self Sealing Coax Heat Shrink Tubing w/
internal sealer, available from
W8AMZ Amateur Radio Products
or a coax sealing type of product
to prevent or minimize line contamination.
