Stationary, omnidirectional antennas
An omnidirectional antenna is an antenna that can receive the signal equally well from all directions. Also known as omni, omnidirectional antenna, etc. An omni-directional antenna can also have a gain. In this case, the radio field is 'flattened', i.e. deformed in such a way that the antenna does not hear as much up and down, but better in the distance.
FM omnidirectional antennas can be found at almost every radio amateur, they are the ideal antenna for local traffic. Vertically polarized like most antennas like relays and mobile stations they are easy to install and unobtrusive in appearance. Multiband antennas offer good performance and trouble-free operation on the most popular FM amateur radio bands such as 2m, 70 and 23cm.
