antenna in the middle, "house antenna"-no find another name for it-is to receive at 137 MHz directly from satellite images of weather service. Is no longer used now for that antennas are much more portable, smaller, cheaper and more presentable.
Something like the picture below. All these antennas can also be used for radio astronomical practices.
