Model No: 915XBISP 

FEATURES: 

 The 

NEW

915XBISP 

high performance Yagi, is the latest product to come out of 

M2’s

 Engineering Lab. Using 

our customers’ suggestions, we have black powder coated the entire antenna creating a hard finish that is tougher than         
conventional paint. Solid 5/16” aluminum rod is used for the element structure allowing for slight rain and snow         
accumulation. Built on a 1” heavy duty boom and includes a heavy duty mounting clamp, allowing for a wide range of 
masts sizes from 1 1/4” to 2”. 

 
The heart of the 

915XBISP

, the folded dipole, provides a virtual flat match for over 30 MHz. Again using our customers’ 

suggestions, the mating connector now faces down for ease of cable connection. The gain has been designed to roll-off 
quickly above range limits to prevent receiver overload from high power services above 930 MHz. 
 
The 

915XBISP 

is a DC grounded antenna designed to work with many radios including Motorola Canopy, Vecima         

Networks, Trango and many others.
