IMT’s slimline omni antennas are highly efficient, wideband, ground plane independent 1, 2, or 3 tier arrays of balanced centre-fed collinear dipoles, housed in a rugged, aesthetically pleasing, fiberglass tube. The antenna has an inline spring making the antenna ideal for camera back applications. The spring allows the antenna to fold over and returns to the vertical position when the obstruction is clears. High performance with consistent gain and radiation patterns across their wide operating bands results from a unique conical dipole and double isolating choke design preventing stray currents on the feed system. See the datasheet for a schedule of frequency bands and gains available.
