Line 71: === Helical resonator === {{main\|Helical resonator}} A helical resonator is a [[helix]] of wire in a cavity; one end is unconnected, and the other is bonded to the cavity wall. Although they are superficially similar to lumped inductors, helical resonators are distributed element components and are used in the [[VHF]] and lower [[UHF]] bands.<ref>{{multiref\|Whitaker, p. 227.\|Doumanis ''et al.'', pp. 12–14.}}.</ref> == Circuit blocks ==
