coaxial traps antenna

Wire antenna with coaxial cable traps - This multiband antenna 10-80 meters is a home made project by I1BAY. Has been used for SOTA activations with great results. Traps are done with coax cable turns, dimensions are in the attached schema.

An Improved Multiband Trap Dipole Antenna - This improved multiband trap dipole introduces a new trap design and a change in trap location. The antenna features double-coaxial-cable-wound traps having lower reactance and a higher quality factor (Q) than earlier coax-cable traps by W8NX

Coaxial Traps for multiband antennas - A new perspective on the analysis and design of this popular antenna element. By Karl-Otto Müller, DG1MFT

Building Coaxial Traps - This page describes the design and construction materials W8WWV used to build a coaxial cable trap. A coaxial cable trap is a parallel resonant circuit that is usually inserted in an antenna element to enable multiband operation.

Tuning HF Coaxial Antenna Traps - The problem with making your own trapped HF antennas is usually getting the coaxial traps tuned to frequency.
