Description

Technical Field

[0001] The utility model relates to a staggered high-gain logarithmic antenna, and relates to the field of television signal reception. Background Art

[0002] At present, ordinary high-gain logarithmic antennas usually install multiple waveguides on both sides of a fixed pole in parallel horizontally to achieve the reception of television signals. Furthermore, there are also two or three fixed poles connected together at one end, and waveguides are installed horizontally and longitudinally in parallel on each fixed pole, and finally the television signal is received by opening the tail wing. Although the above method achieves high gain, there are still shortcomings in signal reception; at the same time, the traditional method of signal output lines of these antennas is to weld them to welding pieces, and then fix the welding pieces to the fixed poles. This method not only increases the process and cost, but also increases the transmission loss and processing defect rate, thereby affecting the television reception effect. Summary of the invention

[0003] The purpose of the utility model is to provide a wider receiving surface in view of the above-mentioned deficiencies, and at the same time improve the installation method of the signal output line so that the signal output line is directly and tightly connected to the fixing rod, so as to achieve a staggered high-gain logarithmic antenna for the purpose of reducing working procedures, reducing transmission loss and processing defect rate.

[0004] The technical scheme adopted by the utility model is: a staggered high-gain logarithmic antenna, characterized in that it comprises an upper fixed rod, a lower fixed rod, a signal output end and a signal output line, a plurality of upper waveguides are installed on both sides of the upper fixed rod, and the upper waveguides on both sides are staggered, a plurality of lower waveguides are installed on both sides of the lower fixed rod, and the lower waveguides on both sides are staggered, and at the same time, the upper waveguides and the lower waveguides are not located on the same side when on the longitudinal radial line; the signal output end is arranged on the lower fixed rod, and fixing grooves are arranged on the lower fixed rod and the upper fixed rod, and the signal output line is led out from the signal output end and extends out along the lower fixing groove on the lower fixed rod and then extends into the upper fixing groove on the upper fixed rod to realize connection.

[0005] The staggered high-gain logarithmic antenna is characterized in that it also includes a bottom cover and a fixing clip, the bottom cover is fixed on one end of the upper fixing rod and the lower fixing rod, and fixes the connection between the signal output line and the upper fixing rod, and the fixing clip is fixed on the other end of the upper fixing rod and the lower fixing rod.

[0006] The staggered high-gain logarithmic antenna is characterized in that buckles are provided on one end of the upper fixing rod and the lower fixing rod, and the buckles match and are fixed with the positioning holes on the bottom cover.

[0007] The utility model can be used to enhance the reception of television signals because the upper waveguide and the lower waveguide are arranged in a staggered three-dimensional layout. At the same time, the signal output line welding type is changed to a direct compression connection, which reduces the process, transmission loss and processing defect rate, and is more conducive to signal transmission.
