Assembly Instructions:
Specifications:
• Fr equenc y range: 88- I 08MHz
• I mpedanc e: 5 0 Ohm
• G a i n : 3. 4dBi
• V S W R : Less than 1.5:1
• B a n d - wi d t h after tuning. 3 MHz
• M a x Power input: 200 Watts
• L e n g t h : 8 8 MHz 9 8 inches (2490mm)
108MHz 7 5 inches (1905mm)
• We i g h t : 2lbs 7ozs (1.1kgs)
I) D eter m i ne the transmit frequency using the chart. Adj us t the length extending
beyond the lower element. I t is not necessary for the upper element measurement
to be exact. I f within 1/2 inch of the target length, SW R will be within acceptable
levels.
2) A t t a c h the assembled elements to the power feeding coil.
3) A t t a c h the three radials to the power feeding coil and tighten the nuts with a
wrench.
4) As s em bl e the two mounting brackets to the support pipe. Pass your coax through
the pipe and connect to the SO-239 connector.
5) S l i de 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. I f possible, check your system for SWR of less than 1.5:1 be-
fore transmitting.
