Generally, directionality is tricky to do handheld over a wide bandwidth.
Another approach is a phased rx array, could even be as few as 2 antennas, and from that you get a bearing too.
- amatecha 2y agoMay I introduce you to: the Log-periodic dipole array antenna[0], allowing quite a broad response range with decent directionality in a single antenna. There's probably a practical limit to just how broadband you can make one, but just from a quick search I found one commercially-available antenna[1] that covers 120mhz-2.5ghz, for example.

- bobmcnamara 2y agoDidn't read it, but it's going to be poor directivity for that meager bandwidth. If you're going to go with that wide of a beam why not use a single element and wave it around? I should also mention the third trade off, size, plays into this tool.
