Technical features of the whip antenas

Hey everyone

Could someone tell me what is the tech features of the kraken whip antenna?

Data like:
Frequency range;
Gain in different frequencies;
Impedance.

By the way, is there any Data Sheet of these antennas?

Since now, thank you.

Hi, the usable frequency range is around 100 Mhz to 1 GHz.
