Antennas What, If Anything Within Reason, Would Make Rabbit-ear Antennas Work Better?

What, if anything within reason, would make rabbit-ear antennas work better? - antennas

I live in a small building with 7 floors of condominiums in downtown SF and rabbit ear antennas Crouching generics are not worth it! Where can I go shopping for a viable alternative? All I can do, and / or add, I welcome a little better. I'm almost 3.4 channels of course, everything with snow. Help!
