The 213-10 is an easily assembled, medium sized, computer designed Yagi that covers 210 to 217 MHz. Original designed for channel 13 TV stations, this antenna has a flat gain and VSWR. Strong, yet lightweight and streamlined, it compliments any VHF system. The heart of the 213-10 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.
