A plastic plate was used so that the pattern of the substrate did not touch the metal.

I was able to connect to the car whip antenna and received only digital signals such as JT-65 and FT-8 (7.074Mhz, 14.074Mhz USB)
To compare with FT-857, I connected the same antenna to the FT-857.
I did not feel a big difference because the area and antenna was not good.
Because digital communication is possible using FT-857 in the this condition, uBITX is also expected to be enough for digital communication.
