Why the complete system matters
Traps provide compact multiband behavior but add component loss, weight, voltage stress, weather exposure, and interactions. Non-trap designs can be longer or mechanically more complex in different ways.
The assumption that breaks it
A trap does not simply become a perfect open circuit on one band and invisible wire on another; current and reactance exist across frequencies.
Build or deploy it correctly
Choose from required bands, space, power, weight, maintenance, and efficiency; follow exact trap placement and orientation, weatherproof it, and verify every band after final installation.
Use the exact product guide, electrical topology, geometry, materials, loading, feed, return path, support, and environment. Mechanical fit or a visually similar arrangement does not establish electrical equivalence.
