A hydraulic antivibration device is provided that is capable of suppressing generation of strange sounds while ensuring a low dynamic spring characteristic upon inputting of relatively small amplitude vibration and a high damping characteristic upon inputting of relatively large amplitude vibration. To that end, upon inputting of relatively large amplitude vibration, displacement-regulating ribs of one of sandwiching members serve to regulate displacement of an elastic partition membrane pinched by the sandwiching members thus obtaining a high damping characteristic. The displacement-regulating ribs consist of three pieces extending radially and rectilinearly, so that the area of openings of the sandwiching members is made wide enough to ensure more a low dynamic spring characteristic. Displacement-regulating protrusions of the elastic partition membrane are disposed to correspond to the displacement-regulating ribs thereby ensuring to suppress the generation of strange sounds.

The invention discloses a double-frequency transmitting monopole antenna for portable high-frequency ground wave radar. The double-frequency transmitting monopole antenna consists of an antenna upper section, a wave trap, an antenna lower section, a feed base and a ground network, wherein a conductor on the antenna upper section is h1 high and a conductor on the antenna lower section is h2 high. When the wavelength lambda 2 corresponding to the radar signal frequency f2 meets a formula of h2=k lambda2/4, the wave trap makes resonance oscillation so as to equivalently isolate the antenna upper section and ensure that the antenna upper section becomes a typical quarter-wave vertical monopole on the ground and has a major lobe of a radiation directional diagram along the ground surface. When the radar signal frequency is far lower than f2, the wave trap is in dissonance, so that the whole height of the antenna is equivalently increased to h3, and therefore the whole antenna forms a quarter-wave monopole with resonance being in lower frequency f1, meets a formula of (h1+h2+h3)=k Lambda 1/4 and has a major lobe of a radiation directional diagram along the ground surface as well. The double-frequency transmitting monopole antenna disclosed by the invention can work on two frequency bands respectively taking f1 and f2 as central frequencies conveniently, and both the two frequency bands have major lobes of directional diagrams along the ground surface. Besides, the adopted feed base realizes favorable waterproof structure design.
