Marshall transmitters and receivers are now available to Falconers worldwide in 433 MHz (UHF) versions.

The 433-434 bands have been widely used in the UK and Europe for many years. However, in the US, they are Amateur Radio bands and regulated by law. US falconers with a HAM license can have the Marshall transmitters broadcast their Call Sign in Morse Code once every ten minutes as regulations require. Getting a Ham license is inexpensive, worthwhile and easy.

The antennas on the transmitters are much shorter, about half the length, as shown here on a BackPack mounted peregrine falcon. The shorter length can make the transmitters safer to use and lower the risk of tangling with quarry.

The antennas on the receivers are much shorter, about half the size. This makes the overall receiver design much more compact and easy to use while walking or inside the vehicle.

The new Desert case is also half the size. Shown in this picture is the 433 Desert Case on the left, compared to the 216 Desert Case on the right. Both are custom modified Pelican cases with special foam inserts to protect the receiver from damage. These are the highest quality protective cases in the world and are waterproof and airtight.

Shown here is a complete system:

1- Custom Desert Case with special inserts

2- UHF Field Marshall, with it's handle removed and in the slot

3- two RT Turbo transmitters and batteries

4- Marshall Tailmount install tool and two large-size tail gold pieces

Every Field Marshall has been designed to be reconfigurable. A Quick-release attachment with simple thumbwheel lets you easily remove the yagi antenna or handle from the receiver case.

These attachments match each other so that the handle can then be attached directly to the yagi antenna in the same secure way.

This also means that the Marshall yagi antenna can be connected to another receiver.

In many parts of the world, the receivers are carried over the shoulder by the falconer using this cordura Field Holster, included with every receiver sold.
