Building Coaxial Traps
- This page describes the design and construction materials W8WWV used to build a coax
ial cable trap. A coax
ial cable trap is a parallel resonant circuit that is usually inserted in an antenna element to enable multiband operation.
- The Coax
trap program computes design parameters for the construction of coax
for HF usage. Typically these are constructed from PVC tube and RG58/59 coax
Bootstrap coax traps for antennas
- Analysis of an antenna trap where a coil is formed of a length of coax
cable, the outer conductor of one coax
end is tied to the inner conductor of the other coax
end, and the remaining connections form the terminals for the trap.
