The reason for this is that coated wire can be easier to work with as if it touches something conductive such as metal it is OK. Bare wire must be kept away from anything conductive to work properly. If bare wire comes into contact with anything conductive that material becomes part of the ...

NettetBare copper grounding wire is less expensive than insulated grounding wire and works well in many industrial applications. Particularly for large projects, using bare copper may yield significant cost savings. In some cases, bare grounding wire may also be less labor-intensive, as it doesn’t need to be stripped before termination. Nettet9. feb. 2024 · The effect of insulation on wire antennas.

NettetHalf-Wave Dipole Length. The “traditional” formula for the length of a half wave dipole is 143 / F in meters (or 468 / F in feet), where F is the frequency in MHz. However, this is only a rough estimate, and doesn’t consider several other factors. We can get a sense of the variation by modeling a dipole that is 20 m (65.6 ft) long.
