Spring antenna on Wireless Tracker v1.1

The spring antenna on the wireless tracker basically sucks. I desoldered it and added a 29mm piece of wire anf tripled my range. However, I’d rather have a very high gain antenna which would require an external antenna. Why doesn’t this board come with a u.fl connector for the WiFi/Bluetooth 2.4Ghz antenna? I’d pay a couple extra bucks per board if I didn’t have to modify it so it had longer range. Any ideas?

Thanks!
