Omnidirectional Antennas
Made in Germany

Schwarzbeck LogoTMC Design Logo 

Made in the USA

An omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis. When graphed in three dimensions this radiation pattern is often described as doughnut-shaped.
