50 MHz 5 element EMT Conduite Beam
A practical blueprint for a 5-element Yagi beam antenna using EMT conduit for 6 meters.
Description
Presents the mechanical and electrical specifications for a 5-element Yagi beam antenna designed for the 6-meter band. The resource details element lengths, spacing, and boom dimensions, specifically utilizing EMT conduit for construction. It includes a diagram illustrating the element layout, a coaxial balun connection, and a reported SWR curve, providing a practical blueprint for hams to replicate the design.
The design achieves a reported SWR of 1.1:1 at 50.125 MHz, indicating efficient impedance matching across the primary 6-meter DX window. The boom length is specified at 2.44 meters (8 feet), with element lengths ranging from 2.87 meters for the reflector to 2.59 meters for the director 3. This configuration suggests a gain figure typical for a 5-element Yagi, likely in the range of 9-10 dBi, making it suitable for local and sporadic-E DX contacts.
