In that case, the signal becomes much stronger.<\/p>\n<p style=\"padding-left: 40px;\">Tuning is done with a 900 pF variable capacitor. To listen to mediumwave, I simply disconnect one side of the shortwave loop. With just that single variable capacitor, I can tune all of the bands.<\/p>\n<p style=\"padding-left: 40px;\">It\u2019s a surprisingly effective antenna for small portable receivers, and it\u2019s built entirely from recycled materials\u2014at no cost.<\/p>\n<p style=\"padding-left: 40px;\">I hope you enjoy it.
