Further, the broadband dipole antenna be triangle dipole antenna, three triangular ridges of triangle dipole antenna Grafting locking connects successively on side, and aerial plug, aerial plug socket antenna pedestal are connected on any one triangle seamed edge.

Further, three triangle seamed edges splicing position is equipped with the hasp of locking grafting.

Further, described two suit the hasp that section splicing position is equipped with locking grafting.

Further, described first and second suit section suit the electric connector of square tube grafting for coaxial cable connector N-J and N-K connections.

Further, the electric connector of the antenna oscillator and oscillator socket is Q9 connectors.

Compared with prior art, the beneficial effects of the invention are as follows：

1st, log-periodic antenna is suited line, broadband dipole antenna by the way of plug Split assembled, antenna structure It is easy for assemble or unload, using maneuverability, pack Quick portable.

2nd, two suit corresponding two groups of line and suit square tube, one group by the way of male and female insertion, another group is suiting square tube The connection mode of coaxial cable connector N-J and N-K is inside adopted, grafting is accurate, convenient, and cooperation splicing position hasp is fixed, it is ensured that letter Number circuit connection transmission performance is unaffected.

3rd, antenna oscillator uses the frame mode of Q9 connectors, and oscillator insertion Q9 base jacks are slightly turned clockwise, make to shake Sub- pedestal spring pops up firmly clamping oscillator, takes into account grafting convenience and communication efficiency.

4th, broadband dipole antenna uses equilateral triangle triangle dipole antenna, using the package assembly mode of plug, three Triangle seamed edge forms a triangle antenna, convenience in transport and carrying.By two equilateral triangle antennas and logarithm period The aerial plug of antenna connection is inserted into log-periodic antenna and suits in the jack of end antenna base of line respectively, makes broadband dipole Sub-antenna and log-periodic antenna is organic is assembled, the secondary complete 30-3000MHz ultrashort wave wide band logarithmic cycles day of composition one Line has reached preferable communication efficiency.

The Antenna Operation frequency range is wide, and unique structure is easy for assemble or unload, using maneuverability, packs Quick portable, antenna High gain, same effect is good, and motor vehicles field is facilitated to communicate.
