The 610-21A is a high gain Yagi, computer optimized for use in the 607-620 MHz band and can be used for transmit or receive functions. Mechanically, the 3/16" rod elements are mounted through the boom, insulated and locked in place with stainless keepers.
The heart of the 610-21A 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 coaxial connectors are triple O-ring sealed. Other key mechanical and electrical parts are CNC machined from 6061-T6 aluminum and all hardware except U-bolts are stainless steel.
The 610-21A offers uncompromising performance, enduring mechanical construction and long term electrical integrity.
