How a yagi antenna works
WebA lower resistivity means you will need less of a metal to reduce the resistance to an acceptable target. Here's a selection, ordered from lowest to highest resistivity in nano-ohm-meters (nΩm), of some metals you might consider using in an antenna: Silver: 15.9. Copper: 16.8. Gold: 24.4. Aluminium: 26.2. Zinc: 59.0.

Web11 de abr. de 2016 · This is how a Beverage Receiving Antenna works. While they are highly directional, they are abysmally efficient, <1%, and peak gain can be as low as -20dBi because of this poor efficiency. The receiver compensates, however. You don't care about SWR, so long as it isn't incredibly high, like >20:1, for the same reason.
