I don't have one here to measure, but such antennas are always highly compromised when working over the huge frequency range of the HackRF. At the low end, it's practically a paperclip, and at the high end it's way too long.
You've heard the expression, "Better, Faster, Cheaper, pick any two"? With antennas it's gain, bandwidth and pattern, pick any two. cover I can't offer too much in specific, there are lots of possibilities depending on how it was designed. The ARRL Antenna manuals are a very good resource, covering practically DC to Daylight.
