The feature that omnidirectional covers, open antenna particularly boat-carrying, airborne communicating antenna it is also desirable to have anti-lightning strike merit
Energy.The high efficiency of antenna is mainly obtained by the coupling of radiant body electricity size, for wideband omnidirectional sky
For line, in order to ensure the electrical property of whole band antenna, its size is less than normal, so makes its sky
Line low side inefficient, improves the way that low side efficiency can use electricity size to increase, if increasing longitudinal ruler
Very little, then high-end antenna radiation pattern will be affected, if increasing lateral dimension, then antenna complete
Will be affected to out-of-roundness, therefore, exist between the bandwidth of antenna, omni-directional, efficiency, directional diagram
A series of contradiction；Due to the construction features of antenna itself, most of antennas do not possess anti-lightning strike function,
It is typically employed in antenna delivery outlet and increases spark gap, indirect lightning strike electric current is led and realizes on mounting platform preventing
The function of thunderbolt.
