I'm new to ham radio and sdr. I managed to get a few fm stations on my pc using a nooelec r820t dongle. I figure a better antenna would allow me to receive more bands/frequencies but don't know what antenna to get. I'm in an apt and they won't allow antennas outside so it has to be an antenna I can keep in my apt I've been looking at falcon's dipole antennas but don't know which one to get. They advertise 2m 90 cm etc but like I said, I'm new to this. Which antenna should I get (I have about a $40 limit)? would I be limited to just the advertised bands the antenna advertises? Which antenna would be the most versatile?
