Let them wander together and the characteristic impedance changes along the run; let them touch and you have a short at full power. The spacers keep the geometry honest from the feedpoint to the exit slot -- which is the difference between a transmission line and two wires in a tube.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 14px;\"\u003e\u003cstrong style=\"color:#1a1a1a;\"\u003eWho needs spares.\u003c\/strong\u003e Anyone rebuilding a feedline kit, adding height with an extension, or restringing after a section swap. Three is the standard count for a stock antenna; taller builds and extensions use more. Keep a set on the shelf and a rebuild becomes an afternoon instead of a wait.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 14px;\"\u003eAssembly order matters: the spacers go on before the upper sections join.
