Installation Manual
Model CFM-95SL
5/8 wave LPFM Broadcast
Base Station Antenna
Assembly Instructions:
Specifications:
• Frequency range: 88- I 08MHz
• Impedance: 50 Ohm
• Gain: 3.4dBi
• VSWR: Less than 1.5:1
• Band-width after tuning. 3MHz
• Max Power input: 200 Watts
• Length: 88MHz 98 inches (2490mm)
108MHz 75 inches (1905mm)
• Weight: 2lbs 7ozs (1.1kgs)
I) Determine the transmit frequency using the chart. Adjust the length extending
beyond the lower element. It is not necessary for the upper element measurement
to be exact. If within 1/2 inch of the target length, SW R will be within acceptable
levels.
2) Attach the assembled elements to the power feeding coil.
3) Attach the three radials to the power feeding coil and tighten the nuts with a
wrench.
4) Assemble the two mounting brackets to the support pipe. Pass your coax through
the pipe and connect to the SO-239 connector.
5) Slide the power feeding coil into the mounting pipe and secure it with the hex bolt.
The antenna is now ready to be used. Keep the tuning chart for future use should you
ever need to re-tune it. If possible, check your system for SWR of less than 1.5:1 be-
fore transmitting.

Summary

Antenna Assembly Instructions

Determine Transmit Frequency

Adjust element length based on target frequency for optimal SWR, referencing the provided tuning chart.

Attach Elements to Power Feeding Coil

Connect the assembled upper and lower antenna elements to the power feeding coil.

Attach Radials to Power Feeding Coil

Secure the three antenna radials to the power feeding coil, ensuring they are tightened with nuts.

Assemble Mounting Brackets

Mount the two brackets onto the support pipe, pass coax through, and connect to the SO-239 connector.

Mount Power Feeding Coil

Slide the power feeding coil assembly into the mounting pipe and secure it with the hex bolt.

Outdoor Installation Safety and Warnings

General Safety Precautions

Follow all safety instructions, use non-conductive tools, and work with an assistant for outdoor installations.

Power Line Proximity Hazards

Maintain a safe distance from power lines; assume all overhead lines are live to prevent contact.

Electrical Shock Response Procedures

Guidelines for assisting someone in contact with electricity, emphasizing not to touch the person directly.
