This not only means your signal is not going as far as it should — you also run the risk of the reflected energy damaging your transmitting device i. While doing that, make sure there are no objects that can interfere with the antenna reception. The signal pattern from such antennas tends to be disk-like in a horizontal omnidirectional pattern, 360 degrees around the antenna. While antenna farms might look cool, they typically mean degraded performance for all antenna-based devices.
