Description
MAXIMUM SENSITIVITY
Getting the best range requires having the most “useful sensitivity” in a receiver. The combination of receiver, the matching cable and the antenna designed for specifically for it constitute a complete package that must work in harmony to achieve the most sensitivity possible. The Digital Field Marshall will give the most range of any Tracking Receiver in the World. Nothing goes farther than the Field Marshall, especially in cities or areas of “unwanted radio noise.” With better than -154dBm sensitivity, the Field Marshall can discern the weakest signals.
USE WITH GPS
Adding a Field Marshall UHF to your GPS system allows you to precisely locate the transmitter inside GPS denied environments (inside a building, or locate the signals when GPS satellites are blocked), or when the transmitter is in thick cover. Using the Field Marshall UHF to track the “Beeping” signal from the RT and Turbo GPS extends range when the transmitter is close to the ground.
EASY TUNING
Tuning with the enhanced tune knob is broad and is protected from accidental contact so it’s not easily bumped off your tune setting when getting in and out of the vehicle.
LIGHT WEIGHT
Using newest generation electronic components, a collapsible yagi and creative packaging allows us to fit a lot into a small space.
And, our commitment to using aluminum alloys which have the maximum strength to weight ratios makes this receiver as light and strong as technically possible.
WATER RESISTANT
Almost. The receiver is not designed to be used in very wet conditions, yet it will hold up in light rain. If it is accidentally submerged through accident or fall, it should be drained and allowed to dry before re-using.
OPTION TO USE VEHICLE TO POWER RECEIVER
The car adapter is designed to bypass the batteries and power the receiver for extended periods inside the vehicle in order to save the batteries, to preserve them for long walks away from the car. The cigarette lighter adapter can found in the accessories. The Field Marshall uses common easy to find AAA batteries which are not rechargeable.
WHAT BATTERIES TO USE
For general use, Alkaline AAA batteries are the most cost effective and provide good battery life but Lithium AAA batteries offer the best performance in cold weather, are the lightest, and last the longest. Remember to always remove batteries from your receiver during periods of long storage (off season). Rechargeable batteries (such as NiCad or NiMH) should not be used as they do not provide sufficient and consistent voltage to operate the receiver effectively.
Always use name brand batteries (like Energizer or Duracell) with a comprehensive warranty, in case there is ever an accident with the actual batteries inside your receiver.
OPTION TO USE WITH OMNI ANTENNA
The Field Marshall easily excepts input from an external antenna, simply remove the coaxial cable from the receiver body, and plug in the coaxial cable from your external antenna. The Field Marshall uses a ‘SMB’ connector, some external antennas may require an adapter.
COMPACT COLLAPSIBLE YAGI ANTENNA
The Field Marshall UHF comes with our latest generation collapsible yagi antenna as standard.
Coverage
The Field Marshall 500 covers the first 500KHz of the band (434.000-.499).
What are the regulations for using the 433/434MHz band in the United States and Canada?
The use of the 433 (or UHF) band in the USA & Canada requires the user to apply for a Ham Radio License (easily attainable by paying a small fee and passing a written test). Once done, the user is now a legal ‘station’ and is able to use the quiet UHF band and at much higher power levels. To legally use telemetry on this band, your transmitter must broadcast your station ID (Ham Radio Call Sign) once every ten minutes in Morse Code (a feature exclusive to Marshall transmitters). You simply provide us with your Call Sign and we’ll include it in each of your UHF transmitters.
