Go for it!
I'm the sysop of a GA WebSDR and its a fun hobby. I am about to swap in an Active Mini-Whip antenna. I am amazed at how well those little suckers work! I home-brewed one, then just for fun, grabbed one off of Amazon for ~$12 and the Amazon model works great. I did use my own build for the DC injector and there are a few things you need to do to make it work better.

This thing works great from VLF up to 20 meters. I can even see the 60kHz WWVB signal on the waterfall. Its pretty cool.
