What determines the accuracy?

Assuming that proper processing is done, the accuracy is determined by the number of antenna elements. A four element array has a one sigma or typical accuracy of about 2.5 degrees and an eight element array has a one sigma or typical accuracy of about 1 degree. For mobile operation, Read more…

What is the sensitivity?

On our first direction finders, the receiver’s squelch was used to determine whether a signal was present or not. It was necessary with these models to adjust the squelch so that the receiver remained squelched under no signal conditions. The sensitivity was then equal to the squelch threshold of the Read more…

How do you measure accuracy?

We measure accuracy under very controlled conditions that are designed to eliminate multipath reflections. The DF antenna is rotated on an index head and the bearing angles are recorded at 1 degree intervals. The error at each angle is then calculated and the mean and standard deviation computed. This process Read more…

Can I transmit close to the DF?

The preamps used are rated at 100 milliwatts maximum input and in our series 7000 direction finders we provide additional protection that increases the rating to about 1/2 watt. Transmitting 10 or more watts from a mobile antenna a few feet away in the same band will probably damage the Read more…
