Summary of the invention

Main purpose of the present utility model is to provide a kind of domestic aerial, links the medial and lateral receiving sheet by coil, and have a gap between the receiving sheet of medial and lateral, and can receive UHF and VHF frequency range simultaneously.

In order to achieve the above object, the utility model provides a kind of domestic aerial, mainly be made up of end box, enclosing cover, signal amplifier and receiving sheet, described receiving sheet is connected in described signal amplifier, and described signal amplifier and described receiving sheet are inserted end box and covered by enclosing cover; Described receiving sheet is located at described signal amplifier both sides respectively with symmetrical manner, and described receiving sheet is a metal material; Inboard receiving sheet is triangular in shape, and protrudes out a link piece and combine with described signal amplifier; Outside receiving sheet be a semicircle, and described inboard receiving sheet and described outside receiving sheet utilize coil to link together, and leaves a gap between described inboard receiving sheet and described outside receiving sheet.

During enforcement, box of the described end links bracing frame or foot rest.

Compared with prior art, domestic aerial described in the utility model, be used to receive TV VHF and uhf band, it is mainly by box body, signal amplifier, receiving sheet and coil are formed, be positioned at the signal amplifier both sides and be provided with receiving sheet with symmetrical manner, and inboard receiving sheet omits triangularity, as for outside receiving sheet then is semicircle, in described, outside receiving sheet utilizes coil to link together, and in, has a gap between the receiving sheet of the outside, and can will receive only the inboard receiving sheet of uhf band originally, by the setting in coil and gap, make the range of receiving of antenna can extend to the VHF low frequency partly.And when signal amplifier and receiving sheet are inserted end box, again enclosing cover is covered and press into end box, can utilize bracing frame or foot rest, make domestic aerial can be hung on wall, upright or yaw is located in the plane, and can receive UHF and VHF frequency range simultaneously, not only handsome in appearancely do not take up space, more can arbitrarily put in indoor and can be not lofty, quite convenient and practical.

Embodiment

At first, see also shown in Figure 2, three-dimensional exploded view of the present utility model, it is mainly by end box 4, enclosing cover 40, signal amplifier 3, receiving sheet 2 and coil 20 are formed, be positioned at signal amplifier 3 both sides and be provided with receiving sheet 2 with symmetrical manner, described receiving sheet 2 is metal material (as a tinplate), be convenient to the signal of reception antenna, and inboard receiving sheet 21 omits triangularity, and protrude out a link piece 211 in central authorities, can be semicircle as for 22 of outside receiving sheets for being connected conducting with signal amplifier 3, and utilize coil 20 that inboard receiving sheet 21 is linked together with outside receiving sheet 22, simultaneously interior, outside receiving

sheet

21,22 have a gap 23.When signal amplifier 3 and receiving sheet 2 are inserted end box 4, and utilize enclosing cover 40 to cover to press into end box 4, promptly finish the assembling (as shown in Figure 3) of domestic aerial 5.In addition, described domestic aerial 5 cooperates bracing frame 41 or foot rest 42, can directly domestic aerial 5 be placed in desktop or received signal on the plane arbitrarily, also can use on the wall by wall hanging, especially can receive UHF and VHF frequency range simultaneously, not only more do not take up space and handsome in appearance, more can arbitrarily put in indoor can be not lofty yet.

Then, please still consult shown in Figure 3ly, described domestic aerial 5 is disposed across received signal on desktop or the plane by foot rest 42 and can directly support.And the utility model also can uprightly be positioned on plane or the desktop, sees also shown in Figure 4ly, turn 90 degrees as long as revolve, and domestic aerial 5 is upright, utilizes foot rest 42 to be supported on plane or the desktop equally and can put.Can certainly in advance bracing frame 41 be locked on the wall, cooperate shown in Figure 5, the location hole 45 (joining shown in Figure 10) that this moment, domestic aerial 5 back sides were offered, combine with the reference column 411 of bracing frame 41, and can use and do not take up space (as shown in Figure 6) in wall by wall hanging, do not worry because of collision influences reception yet, very convenient.
