Basic question for the RF inclined... Improving an antenna by connecting it to the ground of a 3-prong outlet!!!

I had a thought the other night. My wireless keyboard has limited range when my Home Theater PC (HTPC) is enclosed in a cabinet. I have already tapped into the keyboard receiver to access the antenna trace on the circuit board by adding a long wire which I string away and outside of the cabinet. This improved the range. Then I had my thought, what about wiring my external antenna wire into the ground of a 3-prong power outlet. I thought about testing the voltage and current between the antenna wire and ground prong but decided what the heck it is suppose to be grounded. Well, the range is well extended now, but I am wondering what are the risks? I am probably risking damage to my keyboard receiver but so far it works great. I am a very amateur electronics person so I know some stuff but I don't know what would be the best solution to protecting the receiver from damage, if it is needed at all. My questions are why shouldn't I do this, what are the risks, and is there anyway to do this while minimizing the risks?

Also, what about 802.11b? I am thinking that is even more risky since the AP is both a receiver and transmitter and grounding the transmitter signal would probably diminish its range substantially.

Thanks!

Hmmmm.... whatever works, I guess. That antenna trace was tuned to a specific frequency. By adding a wire, you de-tuned it. I would have expected this would make it less effective, not more. Then you grounded it. This should have killed any signal. But apparently both actions had the opposite effect to that which I would have expected. But then, I'm not a communications expert, so.... whatever works. Having it grounded shouldn't hurt it as far as I know.

Of course, with the wire added, you're no longer "wireless", now are you? Might as well buy a normal keyboard if you are going to tether yourself anyway. :)
