#2 - ATTACH COUNTERPOISE WIRES

There are three counterpoise wires for the R7000
+
. Each is twenty
feet long (Figure C). The counterpoise wires provide a proper
match for 80 meter operation on the R7000
+
. The anti-resonator
in each counterpoise wire keeps the twenty foot length of wire
from detuning the higher frequency bands.
The three counterpoise wires attach to the R7000 base with existing
hardware (Figure B). Each counterpoise wire is tied off to one of
your three guy points. Tie the wire and rope together in a knot.
No insulator is required. Tape knot to prevent snagging. The
counterpoise wires should hang at an angle between 60 and 90
degrees relative to the support mast (Figure D). The ends of each
wire should be three or more feet above ground to minimize
detuning. Do not over tighten these wires. Do not use them
as guy supports.
