Model No: 2.4-18R 

FEATURES: 
 

The 

2.4-18R 

is a high gain, Wave Guide Fed Yagi. Computer optimized for use in the 2350-2500 MHz band. 

Mechanically optimum computer calculations are held by CNC stamping out the director element structure. The low-loss 
Polyethylene Radome covers and adds to the strength of the antenna. Vertical or Horizontal polarization is achieved 
simply by rotating the antenna 90 degrees.  
 
The 

2.4-18R 

is one of the best performers for it’s size in the market. If more gain is required, stacking two at 8”  

apart nets another 3.0 dB gain. All antenna hardware is stainless steel for long life.  

SPECIFICATIONS: 

*Subtract 2.14 from dBi for dBd
