Signal interference is a source of annoyance to listeners. It degrades the quality of reception of the desired broadcast program.
Severe interferences can cause the received signal to be completely unintelligible.
This is very disturbing for dedicated listeners of broadcasts affected by such harmful interference. An interference-reducing antenna described below has been shown to increase the program intelligibility. It is of simple design, low cost, and can be built from material commonly available to most households. An additional telescoping whip antenna similar to the one used with the receiver radio or a stiff wire. Two pieces of Aluminum foil having same width and length as those of the portable radio receiver A clean piece of plywood or equivalent, non conducting of electricity, big enough for overall support Two short pieces of connecting wire with screws for connection as required.
