For direction finding, I ordered a handheld yagi antenna for the UHF radio from Arrow Antennas (arrowantennas.com)
Arrow II Hand Held Portable, Item# 146-3BP
Female SMA to BNC Adaptor, Item# FSMA-BNC

Here is a handheld yagi antenna that you can build

I like the design philosophy of the tBeacon. It can pick up GPS position from the 3DR Solo GPS, and transmit it via UHF radio.

Receive the GPS position and 3DR Battery voltage via an inexpensive $30 to $40 UHF 2 meter Baofeng UV-5R radio:
