Where economy is important, these Yagis are your best choice. Aluminum 3/16 inch (.5 cm) rod elements and 7/8
inch (2.2 cm) booms are standard with economy Yagis. The PE457-6 features insulated, through-the-boom element
mounting. The P406-3 and P457-3 6dB models have the elements mounted on the side of the boom.
