My son wants to eventually do a Fox Hunt some day. I think it would be really fun.
On another note, we finally received his antennas. Now we just need to find some cable at an affordable price long enough to make the runs. We also need to figure out how to ground the antennas for lighting strikes properly. The military antennas and stuff I was used to working with had grounding nuts and posts and stuff, but this stuff doesn't.
This is known as a TDOA, Time-Difference-Of-Arrival detector and is a kit available from:

I am using a 8 foot ground rod purchased at Home Depot.
I am thinking about hooking it to the ground for my house that is outside.
I the house has a ground rod, you could use that as well, but it is recommended to have one as close to where the antenna's enter the house. it is also a good idea to consider lightning protectors.
