Introduction

The RA-17 antenna is a foldable three element antenna based on the Yagi-Uda antenna array design. This three element design has a good front to back ratio and deep side nulls. The elements are foldable. The design is considered to be a "brush buster" and is great for applications where the antenna will be abused and other antennas might be damaged or broken. The replaceable elements are available in kits sold separately. The elements can be easily replaced in the field with few tools. This is the durable version of the old style 3 element antenna that many researchers used in the 1970's.
