This plastic box is 141mm (5.55 inch) long. The active board with a low-noise transistor is much smaller. The transistor is not shielded against electromagnetic and radio frequency interference. So I wrapped the entire plastic box with copper tape. The signal is amplified by about 10 dB. The signal quality has improved by approx. 7 dB. Most channels now have 100% signal strength and some 68% signal quality. Good enough.
