The image is a framed poster with a white background and black text. The title of the poster is "Vykres jerábú" which translates to "Vykres jerabu" in English. Below the title, there are three illustrations of different types of antennas. 

The first illustration on the top left shows a red and green antenna with a long pole and a curved antennae. The second illustration shows a green and red antenna with two antennas attached to it. The third illustration shows two antennas on either side of the antennae, one on top of the other. The antennas are connected by a series of wires and cables.

There are also two smaller illustrations on the bottom left and right sides of the image, one of a red antenna and the other of a green antenna. The illustrations are accompanied by text that explains the different antennas and their functions. The poster appears to be hanging on a wooden wall with a decorative pattern.
