Parts list:
No.
1 Power feeding coil 1
2 Mounting pipe 1

4 U-bolt w/lock washer and nut 2
5 Hex bolt 2
6 Hex bolt w/lock washer 1
7 Upper element 1
8 Lower element 1

Note:
In order to keep the high gain of your CFM-95SL antenna, please
use high quality coax of 50 Ohm impedance.
Assembly Instructions:
1) 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, SWR 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.
