The Mexican University of Morelos has developed the world's smallest television antenna, which is not inferior in signal reception quality to its full-size counterparts. It looks like a compact rectangle measuring 11 x 6.5 x 0.6 cm and weighs only 12 grams. When coated, the weight increases to 80 grams.
The antenna can be mounted on the roof without a traditional mast. It is unpretentious to weather conditions, can function even at low temperatures and does not require electricity. A room version is also possible without the need for fixing in a specific place. With a signal splitter, multiple TVs can be connected to the antenna.

According to the project manager Margarita Tespoiotl, the idea of creating a small antenna arose with the advent of new materials and technologies available. For the first time, the mini-antenna was tested in California, where it provided reception of 70 digital channels, and in Mexico City - 28.
