I've worked 160m using an inverted-L and a loaded vertical. Both worked fine but the inverted-L seemed to work better overall. I've used different rigs on 160m including: Drake B line, Kenwood TS-830, Ten Tec Omni VI+ they all worked but the DSP noise reduction in the Omni VI+ was very helpful for pulling CW signals out of the noise on 160m. My comments above on the K7MEM calculator is about the calculator alone. It works, it produces a good starting point for different loaded dipole configurations. Whether a low 160m dipole is a good idea is a different conversation but the calculator does what it's supposed to do in terms of figuring out wire lengths and loading inductors.
