Scanner Antenna Optimum Length For My Scanner Antenna ?

Optimum length for my scanner antenna ? - scanner antenna

I bought a telescopic antenna for my scanner. I am interested in listening to the FM frequency of 130 MHz. I may take up to six antennas, but the frequency, what is the optimal duration of the expansion?

    Optimal quarter wave whip antenna.

    Wavelength (m) = 3 x 10 ^ 8 divided by frequency (Hz)

    or 3 x 10 ^ 8 div from 130 x 10 ^ 6 = 2.3 m

    A quarter-wavelength of 130MHz is 0577 meters.
