Antennas for the SDR Shield
Radio reception on AM, shortwave and amateur radio bands stands or falls by the quality of the antenna used. Good results are easy: you just take a wire 30 meters long and string it ten meters above ground between two trees, as far as possible away from your house. In reality this is not always achievable. So we need to find the ideal compromise: an antenna that is effective, unobtrusive — and small.
