R9
Your Cushcraft R9 vertical antenna is designed and manufactured to give trouble free service. This antenna
will perform as specified if the instructions and suggestions in this manual are followed and care is used
in the assembly and installation. When checking the components received in your antenna package use
the parts listed beside each diagram. There is a master parts list on page 2. If you are unable to locate
any tube or component, check the inside of all tubing.IMP0 RTANT: Save the weight label from the outside
of the carton and lot # from the white label on the carton end. Each antenna is weighed at the factory to
verify the parts count. If you claim a missing part,you will be asked for the weight verification label and
PLANNING

IS IN OPERATION NEITHER PEOPLE NOR PETS CAN COME IN CONTACT WITH ANY PORTION OF
YOUR ANTENNA INCLUDING THE COUNTERPOISE RODS. DEADLY VOLTAGES AND CURRENTS
MAY EXIST . ALSO, SINCE THE EFFECTS OF EXPOSURE TO RF ARE NOT FULLY UNDERSTOOD,
LONG TERM EXPOSURE TO INTENSE RF FIELDS IS NOT RECOMMENDED. THERE ARE SEVEN
WARNING STICKERS WHICH MUST BE ATTACHED TO THE ENDS OF THE COUNTERPOISE RODS
AS SHOWN IN FIGURE E.
MOUNTING
Your mast should be rigid and pointing straight up. Always use a mast at least 1-3/4 inches (4.4 cm) but
not larger than 2-1/8 inches (5.4 cm) in diameter
. If you guy the mast, use

SYSTEM GROUNDING
Direct grounding of the antenna mast is very important for safety.
This serves as protection from lightning
strikes and static buildup, and from high voltages which may be present in the equipment attached to the antenna.
A good electrical connection should be made to one or more ground rods directly at the base of the antenna
or mast using a least #10 AWG ground wire and noncorrosive hardware. For details and safety standards,
consult the National Electrical Code. You should also use a coaxial lightning arrestor, situated outside and

at least 10’ above earth ground for best operation. It cannot be mounted on the ground. Secure a location
clear from surrounding objects such as buildings, trees, power lines, towers, guy wires, antennas and
metallic objects .Ideally, it should be 60’ from any metal vertical structures, such as a tower. The R8 may
be mounted higher than 10’ above earth ground without modification. That is the beauty of its ground-
independent design.
