A 4 Vertical Array ( 4-square ) for 30m
The idea for this antenna originates from Les EA5AVL (SK) who built the ’40m Compact 4-Square Antenna’. A very nice concept. I decided to build a light weight 30m version of it and decided I would design it from scratch using EZNEC. There were constraints: all antenna components had to come from the PA3A junkbox and the array should be light weight and portable.
