In order to ensure effect, described conical disc oscillator is also 16.
The utility model is compared compared with prior art, has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and with low cost, its antenna strut is provided with antenna pedestal, is convenient to arrange disc oscillator and conical disc oscillator on antenna pedestal, and the utility model acts on the ability that can improve the utility model signal acquisition by disc oscillator and conical disc oscillator simultaneously; Meanwhile, its disc oscillator and conical disc oscillator all can rotate, and therefore disc oscillator and conical disc oscillator can be contracted on antenna strut, thereby can reduce volume of the present utility model, can be easy to carry, and be convenient to set up.
(2) described disc oscillator of the present utility model is connected on antenna pedestal by circumferential band, is convenient to rotary disk oscillator.
(3) antenna strut of the present utility model is provided with antenna pedestal upper end and matches and merge the upper platen that can slide up and down along antenna strut, can be convenient to strut disc oscillator by platen on this, is convenient to set up in the time using the utility model.
(4) on upper platen of the present utility model, be also provided with the upper pressing cap matching with antenna strut, can be convenient to promote upper platen by this upper pressing cap and slide on antenna strut, and then strut disc oscillator.
(5) on antenna strut of the present utility model, be also provided with antenna pedestal lower end and match and merge the pressing disc that can slide up and down along antenna strut, can be convenient to strut conical disc oscillator by this pressing disc, be convenient to set up in the time using the utility model.
(6) on pressing disc of the present utility model, be also provided with the upper lower pressing cap matching with antenna strut, can be convenient to promote pressing disc by this lower pressing cap and slide on antenna strut, and then strut conical disc oscillator.
(7) disc oscillator of the present utility model is 16, after these 16 disc oscillators can being strutted when use, can form a circle, thereby after these 16 disc oscillators are uniformly distributed, can carry out omnibearing signal capture, can improve sensitivity of the present utility model.
(8) conical disc oscillator of the present utility model is 16, after these 16 conical disc oscillators can being strutted when use, can form a taper shape, thereby after these 16 conical disc oscillators are uniformly distributed, can carry out omnibearing signal capture, can further improve sensitivity of the present utility model.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail:
Embodiment
As shown in Figures 1 to 3, telescopic type omnidirectional antenna of the present utility model, comprises antenna strut 1.For the ease of antenna oscillator is set, on described antenna strut 1, be also provided with antenna pedestal 2, described antenna pedestal 2 is fixed on antenna strut 1.Antenna oscillator of the present utility model comprises disc oscillator 3 and conical disc oscillator 4, and described disc oscillator 3 is arranged on the upper end of antenna pedestal 2, and 4 of described conical disc oscillators are arranged on the lower end of antenna pedestal 2, and this disc oscillator 3 and conical disc oscillator 4 all can rotate.
Described disc oscillator 3 is connected on antenna pedestal 2 by circumferential band 5, and as shown in Figure 1, disc oscillator 3 of the present utility model is 16.Strut 16 disc oscillators 3 for the ease of disposable simultaneously, be also provided with platen 6 on described antenna strut 1, described upper platen 6 is socketed on antenna strut 1 and can slides up and down along antenna strut 1, and on this, platen 6 matches with the upper end of antenna pedestal 2.Slide on antenna strut 1 for the ease of promoting upper platen 6, on platen 6, be also provided with upper pressing cap 7 on described, as shown in Figure 1.Described upper pressing cap 7 matches to merge with antenna strut 1 and is socketed on antenna strut 1, and the upper pressing cap 7 in the present embodiment is structure as a whole with upper platen 6.When use, promote upper pressing cap 7 downwards, can depress platen 6, upper platen 6 to disc oscillator 3 firmly, can strut 3,16 disc oscillator 3 horizontal openings of disc oscillator, forms a circle, as shown in Figure 2.When contraction, upwards promote upper pressing cap 7, then shrink disc oscillator 3, as shown in Figure 3.
