Abstract

The utility model relates to a receiving antenna device. A vacuum aluminum plating terylene thin film is cut into a wideband compound vibrator, and a VHF frequency range angle-shaped vibrator and a UHF frequency range fan-shaped vibrator are connected with the wideband compound vibrator. The wideband compound vibrator is stuck and sewed in a sandwich layer of curtain cloth material with a sticker. A feeding point of the compound vibrator is connected with a flat feeding line with 300 ohms, the sandwich layer of a curtain is led out, and the utility model is formed. The antenna receives a signal of television frequency at a window of a building. Therefore, the utility model overcomes the phenomena that because of the shielding action of the building having a reinforced concrete structure and the absorption of a wall, a television signal is greatly attenuated, snow points occur, a television program is disturbed, and double images occur. The utility model has various functions.

Description

Curtain type indoor receiving antenna for TV set

The utility model relates to and a kind ofly collects curtain and the television set reception antenna is the window curtain type TV signal receiving antenna device of one.

This machine of use antenna or the domestic aerial TV reception that some is common are often because the shielding action of building and the absorption of wall make electromagnetic wave arrival indoor back decay very big.The building of the especially area of building dense, and reinforced concrete structure, bigger to the attenuation of TV signal, cause TV image unintelligible usually, there be " snow " to disturb and ghost phenomena, effect is watched in influence.

In order to address this problem, domestic aerial should consider to avoid the shielding of room wall as far as possible, places received television signal and be chosen in the window place.But for general indoor reception antenna, be placed on window and use the restriction that then is subjected to antenna volume and shape, inconvenience is arranged more.

The purpose of this utility model is the TV signal receiving antenna device that a kind of improved curtain pattern will be provided, and it can prevent effectively that " snow " disturbs and overcome ghost phenomena, TV receiving effect is improved and improve, and can one-object-many-purposes.

The purpose of this utility model is achieved in that the suitable cloth of making curtain is cut into two identical sizes, long 1.7 meters, wide 1.6 meters, wherein piece of cloth material is stretched and is kept flat in one plane, vacuum aluminum-coated mylar (is moored as aluminium, it is very solid, flexible, anti-kinking and bending, be often used as the compound package material of some commodity, belong to the high-quality conductor) as the material of antenna active dipole, it is cut into two of the composite oscillators that a kind of VHF frequency range dihedral oscillator and uhf band fan-shaped vibrator be connected as a single entity with scissors.On the face of aluminium plating terylene film composite oscillator insulation, smear one deck adhesive sticker equably then, entirely left and right symmetrically pastes on the curtain cloth, the vacuum aluminum-coated mylar composite oscillator sewing that will stick on the cloth with sewing machine is reinforced again, one end of one 2 meters long 300 Europe ribbon feeders is peelled off the plastic peel of 2 centimeter length, the copper wire that exposes is scalded upward scolding tin with ferrochrome, in case this terminals oxidation and rusting.Then these feeder line terminals are received two distributing points of vacuum aluminum-coated mylar composite oscillator respectively.The concrete grammar that feeder line is connected with composite oscillator is: the conductor that earlier the aluminium plating terylene film conductor at feed place is wrapped feeder line, use very thin aluminium flake again, length and width is 2 centimetres, behind the semi-surrounding of feed junction and flat with pliers folder, so that feeder line and oscillator contact point are solid and reliable.The place that ribbon feeder contacts with the curtain cloth is sewed on two diatoms with sewing machine along feeder line, antenna oscillator lead-out wire and curtain cloth have been fixed together.At last the onesize curtain cloth of another piece, with sewing machine two blocks of curtain clothes are stitched together on the topped cloth of pasting the aluminium plating terylene film composite oscillator at this piece, just made the interlayer curtain.Draw feeder terminal and connect Europe, 300 Europe-75 impedance transformation adaptation aerial plug, just finished manufacturing of window curtain type television receiving antenna.

The utility model be because only needing to paste in the interlayer of casement fix the broadband composite oscillator that the vacuum aluminum-coated mylar conductor material of a kind of usefulness is cut into, and is attached thereto and connects, draw a flat TV feeder, so structure is simple especially.Not only can receive all TV programme of VHF frequency range 1-12 channel with it, can also receive the TV programme of many channels in the uhf band.Especially this antenna uses at the window place of building, avoided because the shielding action of reinforced concrete construction and the absorption of wall, the TV image that causes very high attenuation to cause to electromagnetic wave has " snow " to disturb and ghost phenomena, so, the indoor reception antenna of window curtain type television set more helps the induction of television frequency signal is received than general television set domestic aerial.

The concrete structure of utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is concrete shape, structure, the length dimension data of the active composite oscillator that is connected as a single entity of the VHF frequency range dihedral oscillator that is cut into according to the vacuum aluminum-coated mylar conductor material of usefulness that the utility model proposes and uhf band fan-shaped vibrator, and the floor map that is connected with feeder line of oscillator.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device comprises curtain cloth (1), (2) of using two same sizes, so that make the curtain of interlayer.Vacuum aluminum-coated mylar composite oscillator (4), (5) stick on the casement (1) with adhesive sticker earlier, again composite oscillator (4), (5) and 300 Europe ribbon feeders (3) are all sewed on curtain cloth (1) with sewing machine thread, like this can firm and durable.300 Europe ribbon feeder (3) terminals will same respectively composite oscillator (4), (5) two distributing points are connected firmly, the casement (1) that the casement of the same size of another piece (2) and this piece are being fixed composite oscillator (4), (5), feeder line (3) is stitched into the curtain of interlayer then, and the end that feeder line (3) is extracted from the curtain interlayer is connected with Europe, 300 Europe-75 impedance transformation adaptation TV set aerial plug.The indoor reception antenna of making of window curtain type television set when received television program, should be evened up and hang from above on rope or iron wire (6) of window top.
