Cutting Copper for 6m LFA Yagi

Here is a step by step photo album showing how I prepared home center copper pipe for use in a three element Loop-Fed-Array Yagi-Uda antenna (aka LFA Yagi Antenna).

The Coplanar Loop Fed Array (LFA) Yagi-Uda design from G0KSC provides an excellent design foundation for an all copper version of a 3 element 6m balunless beam with superior front to back performance. Shown are comparisons between model simulations and prototype measurements.
