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.
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, most omni antennas use the larger ‘BNC’ connector. A simple adapter (included with the purchase of an omni from Marshall Radio) can be used to connect other vehicle mounted antennas to your Marshall Receiver.
FULL SIZE COLLAPSE YAGI ANTENNA
The Field Marshall VHF comes with a “full size” collapsible yagi antenna as standard. Offer rugged simplicity.
Coverage
The Field Marshall 100 covers the first 100KHz of the band (216.000-.099).
The Field Marshall 4000 covers 4 Full Bands (216.000-219.999).
