Model No: 222-10EZ 

FEATURES: 

 

The 222-10EZ is an easily assembled, medium sized, computer designed Yagi that covers 222 to 226 MHz with 

flat gain and VSWR. Strong, yet lightweight and streamlined, it compliments any VHF system. The heart of the 222-10EZ 
is a unique Driven Element Module with superior weather resistance and power handling abilities. All connectors are O-
ring sealed  to the CNC machined block and internal connections are sealed in a space-age silicone gel with a dielectric 
strength nearly 4 times greater than air. The Balun coax connectors are triple sealed.  
 

Other key mechanical and electrical parts are CNC machined from 6061-T6 aluminum and all hardware except U-

bolts is stainless steel. It features our silicone-gel sealed, weatherproof driven element assembly and a unique internal 
balun. Want higher power capability or some other change? Please contact the factory for details.
