"IN THIS CORNER, THE LIGHTWEIGHT CHAMPION, TAKING UP LESS SPACE AND ALSO WEIGHING LESS THAN A CAN OF SODA..... IT'S THE EGG!!!"
The Egg is an easy-to-use 1:1 Choke Balun for up to 400 watts, with stainless SO-239 connections at both ends to easily plug in your coax feed with PL-259. Combats common-mode interference in a range from 1.8 to 54 MHz (160 meters through 6 meters.) The Egg is waterproof and suitable for a permanent installation, or also great for your field setup or to-go kit.
Thanks for looking!
