Объяснение

The PL-259, or UHF connector, is the traditional amateur connector for HF and VHF work because it is rugged, cheap and easy to install. It is a screw-on rather than bayonet type, it is not watertight, and its impedance discontinuity makes it unsuitable for microwave use despite its UHF nickname.
