The basic equipment to get started on 2m is a receiver,
a directional antenna, and an attenuator.
Most folks start with an HT or a mobile rig for the
receiver. It is good if it has an "S" meter that is
easy to read (you can manage without the meter, but
it is more difficult.)
There are several options for antennas. Yagis and
quads are common, with anywhere from 2 to 6 elements
(or more for the hardcore hunters.) A 2-element quad
is easy to build from PVC pipe and wire - a lot of
the local folks have built them
The attenuator is probably the hardest part for most
beginning hunters. You can buy or build a switched
attenuator, but when you get close your radio will
pick up so much signal through the case that the
meter will be full scale without an antenna. The
answer is an "offset" (or "active") attenuator.
This is just an oscillator and a mixer. There are
several designs floating around on web, including
one on Joe Moell K0OV's website at www.HomingIn.com
(which probably has just about everything you need
to know about transmitter hunting. Joe literally
wrote the book on it! Well, actually, he coauthored
it with WB6UZZ.)
Then you will have to find a way to mount it in the
car. Generally this is done by sticking it out the
passenger window. (It isn't safe to try to drive and
operate the antenna at the same time.) I attach a
short length of PVC pipe to the top of the door
with nylon straps or duct tape to help hold the
mast. (The mast passes through it and drops down
inside the car.)
Now, one thing you will need to clarify is just what
is meant by "foxhunting". In most parts of the US,
this is done primarily in cars, but in other parts
of the world it is done on foot in a large forest.
(Or on skis or snowboards, in some cases...)
Equipment is similar, but tape measure yagis are
prefered over quads, which tend to catch on branches.
(Check WB2HOL's web site for the classic tape measure
yagi design.)
To have the most fun, you need someone to hunt with.
Join the local group if there is one. Otherwise, get
some friends together and have one hide and transmit
while the others look for them.
Good luck, and happy hunting!
