Description

TECHNICAL FIELD

[0001] The present invention is related to digital terrestrial TV antennas for receiving UHF broadcasts, and more specifically to constructive details thereof.

PRIOR ART

[0002] Digital terrestrial TV antennas for receiving UHF broadcasts are known.

[0003] The TV antenna described in ES1038624U comprises a support rod where the dipole or active element and the directing elements are disposed, a die cut part forming the reflector and a fastening part linking the rod and the reflector. The fastening part has a fixing system for fixing to the support rod formed by two pins ending in a wedge encircling the support rod and by pivots fixing said fastening part to the support rod.

DISCLOSURE OF THE INVENTION

[0004] The object of the invention is to provide a digital terrestrial TV reception antenna as described in the claims.

[0005] The digital terrestrial TV reception antenna of the invention comprises a reflector comprising a through hole, a linking rod and a support element in which a plurality of directing elements are distributed.

[0006] The linking rod and the support element are two different elements and an end of the linking rod is housed inside the support element.

[0007] The fact that the linking rod and the support element are two different parts instead of a single part makes the digital terrestrial TV antenna according to the invention more compact when storing and transporting it.

[0008] On the other hand, since the parts are smaller, they are more manageable and this therefore facilitates assembling the antennas, which is generally done at a considerable height and under difficult maneuverability conditions.

[0009] Furthermore, the housing of the support element in which the linking rod is housed serves as a guide for facilitating the assembly, thereby reducing the effort used in doing so.

[0010] These and other advantages and features of the invention will become more evident in view of the drawings and detailed description of the invention.
