2 meter 5 elements antenna. Measured outstanding low SWR from 144 MHz to 146 MHz. Less than 1.1 on whole band. Excellent for Tropo or FM repeater work. Those results are achieved at antenna connector.
144 MHz 5 elements FM and Tropo antenna. Dipole “N” Connector and balun detail on PA144-5-1.5B. Excellent mechanical properties.
Different dipole and element view on high-class 2m band 5 elements antenna. Used different UV-Resistant element insulators that we produce.
Measured Return Loss on finished antenna on antenna connector. All antennas in production are mesured to achieve highest possible results.
On this 2m 144 MHz 5 elements antenna Return Loss is exemplary. What is possible to achieve with superior design with latest professional full-3D electromagnetic modelling software.
Beautifully taken picture on PA144-5-1.5B 2m portable – tropo FM antenna 5 elements.
Measured Smith-Chart taken with HP8753ES 6 GHz Network Analyzer. 5 elements 2 meter Yagi antenna was on working position. Supreme results.
