Continuous Omni-Directional Amplified CA-2500 Antenna

Batwing or the Jack are great options.

If you have a dramatic difference between you and your neighbors try running a coax from their antenna to your stuff. Use it as the signal source and you can use a barrel to couple the signal to your stuff. Of course you need to understand a bit of what you are doing. Or just replace the antenna and go for it.
