Tiny Noodle Tenna for HF limited spaces.
Here's another fascinating HF antenna for limited or restricted spaces. Thanks to Rudi (K7RAW) for this ingenious use of a "pool noodle" for a simple vertical helix antenna covering the 40 through 14 meter Amateur Radio bands. As Rudi explains, this ultra simple HF antenna is ultra stealthy, requires no ground radial system, and is entirely portable.

Here are some comments from Rudi (K7RAW): his is a BRAND NEW type of HF antenna for those with extremely limited space to setup a conventional 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 end. It uses widely available ordinary parts which cost less than
