Model No: 902-5 YAGI
FEATURES:
The 902-5 Wireless internet antenna, has been designed to give you optimum performance for the smallest
package size. The new 5/16” element design decreases the effects of rain and light snow deterioration often seen
in similar antennas.
The heart of the 902-5, the folded dipole, provides a virtual flat match for over 30 MHz. The gain has been designed to roll
-off quickly above range limits to prevent receiver overload from high power services above 930 MHz. The heavy duty
boom and 5/16” elements, give the ISP service confidence for superior performance and longevity.
The 902-5 is a DC grounded antenna designed to work with many radios including the Wave Rider. The 3003 and 3004
Wave Rider radios have internal DC circuit protection built in.
SPECIFICATIONS:
*Subtract 2.14 from dBi for dBd

Step 2:
Attach the folded dipole to the rear
boom section by sliding the unit back
and forth until it is in place.
Step 3:
It may be necessary to remove the first
element to slide the dipole in place.
Attach the dipole with an 8-32 x 1 1/4”
screw.
Step 5:
Attach the mounting U-bolt and Cradle
in the correct polarity holes. Use the
two 1/4-20 hex nuts and lock washers.

lubricant like WD-40 on the threads
of the U-bolt. Stainless material will
seize if not lubricated.
