Just returned from a large exhibition of military hardware in Denmark - talked to Rohde and Schwarz among others - and noticed, that their circular array DF antennas - did not need to be adjusted when frequency changed - diameter remains constant.
Any chance the Kraken will be able to work with a fixed diameter circular array in the future - covering around 100 to 500 Mhz ?
Their PR-200 receiver was awesome b.t.w. - though primarily used a hand-held log-periodic antenna for manual DF - quite a bit slower than a well tuned Kraken.
I believe most military arrays have multiple antennas in them, and they will auto switch depending on frequency.
With the kraken 5-channel and a 50cm array you could cover about 100 - 255 MHz. You need to account for the fact that on the lower end resolution drops though.
If you have a large number of elements, you can expand the range too, as you can use smaller spacing multipliers and not have to worry about resolution becoming poor on the lower frequency end.
Most high end military arrays probably use 8+ or so elements. With an 8 element array you could cover about 100 - 400 MHz.

Number of elements is the answer. Counted 7 on one array, the other was enclosed in a polymer cover, so hard to tell
Seen arrays with many more, 16+
Thanks for the response.
So: How about using two Krakens, clocks syncronized - and a “slight” mod to the software for 10 channel support.
Already looking to buy a second unit for mobile use
Finally - can you read the serial number via software - needed for mapping registration. My Unit is build into a box, mast mounted- to keep cables at the 8 meter delivered by Arrow

The serial number is only available on the outside of the enclosure.
