Range
The Marshall tracking collar was designed to be the most powerful transmitter on the market. It should
provide up to twice the range of most competitive high output models under most hunting conditions.
Like any radio tracking collar, the range of the Marshall collar varies with the terrain. Tests have shown
its range in the mountains of the western United States to be anywhere from 25 to 100 miles,
depending on the height of the transmitter, the height of the receiver, and the type of terrain and
obstructions. Typical eastern, forested hunting conditions give 5 to 20 miles.
If you want to compare the Marshall collar with another transmitter, you must test them at the same
time. The easiest way to do this is to hang the Marshall collar and the collar you are comparing, on a
fence rail or level tree branch and do a drive off test. It is important that both collars be at the same
height off of the ground, and that the antennas on both collars are facing vertically. A quick test can be
done a short distance away judging the relative signal strengths on your receiver, but the best test is to
drive off until you loose the first collar completely, then check the signal of your Marshall collar. As you
are testing, be sure to rotate the yagi antenna on your receiver to the vertical position matching that of
the collar's antenna to find the best signal strength for each collar.
Remember that tests done in different places will always give different results. Even testing at different
times of day can give different results. This is why you must always compare two transmitters by testing
them together at the same time in the same place.
Using the Receiver
The normal way to hold your receiver is with the antenna horizontal. Horizontal gives more pinpoint
accuracy, but if you are tracking a very weak signal, the vertical orientation might be better, so try both.
The signal is strongest if the receiver
antenna is lined up in the same orientation
as the collar’s antenna. Since the collar’s
orientation on the dog and the terrain can
change, always try rotating your yagi from
horizontal to vertical to attain the best
signal possible.
Whatever range you get, you can be sure that the Marshall collar gives you the best signal you can possibly get
under those specific conditions.
