HF Trap Antennas

Introduction

A popular way of multibanding antennas is to install parallel tuned circuits, or traps.  There are two different techniques used.  One technique is to resonate each trap in the middle of the ham bands, while the other is to resonate the traps between ham bands.  The latter, while less intuitive, can offer more bands with fewer traps, if properly designed.
