Measured RL on finished antenna at antenna connector.
All antennas in production are mesured to achieve highest possible results.
On this 5 element rear mount Yagi 144 MHz to 145 MHz Return Loss is exemplary.
What is possible to achieve with superior design with latest professional full-3D electromagnetic modelling software.
HP8753ES 6 GHz Network Analyzer Measured Smith-Chart. 5 elements 2 meter rear mount Yagi antenna was on working position. Superb results.
