Web20 aug. 2024 · The Slinky-wire is "helically" or "spirally" wound - basically a cylindrical coil. The diameter of the coil is small ( < 0.5%) compared to the wavelength that the antenna is used for. Likewise, when the coil is stretched, the pitch of the turns ( = axial distance between successive turns) is similarly small. In this case, the antenna is called ... Web“Tapered Area Small Helix” or TASH for short. Apparently, the antenna was given that “catchy name” to help the article readers remember the antenna. TASH rhymed with trash.
