Abstract
The utility model relates to a U-band omni-bearing TV receiving aerial which is composed of a supporting rod, an oscillator bracket, a connecting box body, reflecting nets, U-band oscillators, a matcher, an amplifier, a power distributor, a cable, etc. The utility model has essential that the U-band oscillators are made into three oscillators which are connected with three equant parts of a circle and are fixed to the box body by the bracket. Thus, the utility model forms omni-bearing orientations of 360DEG. The corresponding position of the rear side of each oscillator is provided with one metallic reflecting net. Due to the adoption of the technical proposal, the utility model can receive signals in an omni-bearing way as well as directly improve receiving gain. The utility model can also be conveniently combined with television aerials of various forms with middle and lower frequency ranges so as to form omni-bearing all channel TV receiving aerials. The utility model has the advantages of novel design, reasonable structure, convenient installation and debugging and obvious receiving effect.
Description
The utility model U frequency range omnidirectional receiving antenna for TV belongs to the television receiving antenna of high band.
" the U frequency range omnidirectional full channel tv receiving antenna " produced receives problem though solved TV signal comprehensive, all-channel at present, also overcome the problem that is used for comprehensive, full frequency band reception antenna complex structure, Installation and Debugging difficulty in the past, but can also further improve by the TV signal receiving gain of practical application, to improve the reception of antenna to high band.
The purpose of this utility model is: provide that the comprehensive receiving ability of a kind of TV signal to high band is strong, gain is high, convenient again and any in, the U frequency range omnidirectional receiving antenna for TV of low channel television receiving antenna combination.
The purpose of this utility model is achieved in that the U frequency range omnidirectional receiving antenna for TV key of being made up of pole, box body, carriage, reflector net, U frequency range oscillator, adaptation, amplifier, electric power source distribution device, cable is the oscillator of U frequency range is made 3,3 five equilibriums (3 directions) by circle are separately fixed on the box body by 3 oscillator carriages, behind each oscillator and establish a metallic reflection net.
Directly improve gain 1-1.6db owing to adopted above-mentioned technical scheme that this antenna is received in comprehensive TV signal to high band, but also can be easily with various forms of in, the television antenna of low-frequency range is combined into full channel tv receiving antenna, thereby improved the overall performance of antenna.
Below in conjunction with drawings and Examples this programme is illustrated:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a connection schematic diagram of the present utility model.
1 pole, 2 box bodys, 3 lids, 4.5.6 carriage, 7.8.9 reflector net, 10.11.12U frequency range oscillator, 13 adaptations, 14 amplifiers, 15 electric power source distribution devices, 16 cables among the figure.
