The R7000
+
requires guying at two points with a non-conductive material
(Figure E). The R80 kit contains 250 feet of UV stable 400 lb. tensile
strength guy rope. This is enough guy rope to secure an R7000+
mounted on an eight foot support mast on level ground. Extra rope
can be used to tie off the counterpoise wires. If more guy rope is
required, use a similar material with equivalent specifications.
Insert three 631 guy brackets into the 411 worm clamps already placed
on the radiator in Step 1. Tighten the worm clamps.
Attach the guy ropes to the guy brackets using a 259 thimble (Figure
2). The thimbles are provided to eliminate wear on the guy rope at this
connection point. Use pliers to open the end of each thimble and insert
the thimble into the hole on the guy bracket. Use pliers to close the
opening in the thimble end. Tie the guy ropes securely and cover the
knot with electrical tape to eliminate snagging during antenna raising.
Notes for raising the R7000
+
1) Ensure your support mast is securely mounted. The base of the
R7000
+
must not be allowed to move.
2) Do not let the guy ropes snag during antenna raising.
3) Walk the antenna up and down slowly
4) The wind loading of the R7000+ is small.
Do not over tension the
guy ropes.
Guy anchors must be securely installed and capable of
properly supporting the antenna.
5) Double check antenna assembly before raising to minimize repeated
raising and lowering.
6) Have sufficient help to perform installation.
7) Check guy ropes occasionaly for tightness and wear. The guy rope
should be replaced every three to five years depending on your
environment. Do not use polypropelene rope.
8) Calculate guy rope lengths before installation using equation in
Figure G. Add extra length for tying off.
9) Sear rope ends with open flame to prevent fraying.
