I am using a software defined radio and am looking for a good (and cheap) airband antenna to hook up to it. The antenna is most likely used indoors and with 10-15 miles of airport. I'm even willing to build an antenna if that makes more sense. I also need to be able to move it easily. Since I have to move it from home, to the office, to school. Any help would be greatly appreciated. Thanks so much.
