Tiny Noodle Antenna for HF Limited Spaces
Here's another great antenna idea from Rudi (K7RAW)...using a "pool noodle" as an HF antenna. The antenna is closely related to a spirally-wound vertical helix, such as a metal "slinky" toy. The antenna works amazingly well for it small size--a perfect fit for apartment and condominium dwellers. Rudi does an excellent job of explaining both the theory and practical applications of this fascinating antenna.

It is derived from the Slinky Antenna but with a few upgrades. It is less than 1/5th the length of a normal dipole, yet performs similarly. No ground, radials, counterpoise, tuner or BalUn required. Just a coax feedline with a Mix 31 common-mode ferrite choke at the antenna e
