Most likely, with such an antenna you will be able to pick up a DVB-T2 digital television signal at a distance of about 20 - 40 kilometers in direct line of sight, or a reflected signal at 8 - 15 kilometers from the television center.
The total length of the wire necessary for the manufacture is: 158 centimeters.
The active receiving part of each frame is its top and bottom horizontal parts.
It turns out that a two-element loop antenna contains four elements and is equivalent to a double-deck phased array assembled from two-element antennas.
The influence of the two additional elements of the second floor is stronger than the addition of two directors to the antenna.
