Qfh Antenna Calculator, 1 mm, and bending radius of 13 mm. Description of the construction of a quadrifilar helicoidal antenna. Free, accurate, and easy to use. PDF | On Mar 10, 2015, George Slade published The Basics of Quadrifilar Helix Antennas | Find, read and cite all the research you need on ResearchGate This document discusses a quadrifilar helix (QFH) antenna designed for UHF frequencies. This is called a "Quadrifilar Helix" or QFH Antenna. This antenna is unique in its simplicity of design and powerful 3DP-QFH is a quadrifilar helicoidal antenna for 137MHz, build out of 3D-printed connection elements, PVC-tubing and welding rod.
