This precaution will prevent damage to the antenna system as the tree sways in
the wind. In soft earth or areas where fixed objects are not available, a dead-man
type anchor may be used. A dead-man anchor is shown in View D of Fold-Out 1.
Whichever anchor you use be sure it's properly installed or the antenna system
won't be up for long.
Guy Stake Installation. Now that you are familiar with the components of the AN/GRC-
103 antenna system and types of antenna anchors, the next thing that must be
accomplished is the location and installation of guy stakes. A procedure has been
developed whereby the guy stakes can be located at proper intervals around the antenna
mast. Open Fold-Out 2 and refer to it while studying the procedure for guy stake
Place the mast assembly upright at the center of the area selected as the mast
With the universal tool, from the accessories kit, and one guy stake, walk 12
paces (30 feet) directly into the wind. Drive the guy stake into the ground
with the universal tool.
Pick up two stakes and return to the antenna mast. Walk 6 paces (15 feet) to
point D and drop one guy stake.
From point D turn right and walk 10 paces (25 feet) to point B. Drive in the
second guy stake then retrace 10 paces to point D.
Pick up the stake that was left at point D and walk in a straight line for 10
paces (25 feet) to point C. Drive in the third guy stake.
By following these five steps each guy stake will be properly spaced around the antenna
mast. Proper guy stake placement will ensure equal tension on the antenna mast.
