The condition for resonance in a monopole antenna is for the element to be an odd multiple of a quarter-wavelength, " ? " / 4.

The traditional typographic units are based either on non-metric units, or on odd multiples ( such as 35 D 83 ) of a metric unit.
13.
Triplen harmonic currents ( odd multiples of the third harmonic ) are additive, resulting in more current in the shared neutral conductor than in any of the phase conductors.
14.
I know that some value of " x " will make both ax and bx equal to an odd multiple of \ pi but can't think of a way to find this value.
15.
Posted speed limits, to conform to the French Highway Code, must be in odd multiples of ten ( e . g ., 10, 30, 50, etc . ), though you can still see 40, 60 and 80 sometimes.
16.
Constructive interference occurs when the phase difference between the waves is an "'even multiple "'of ? ( 180?) ( a multiple of 2?, 360?), whereas destructive interference occurs when the difference is an "'odd multiple "'of ?.
17.
The difference between the two sound carriers is 15.5 times the line frequency ( 15.5 x 15625 Hz = 242187.5 Hz ) which, being an odd multiple of half line frequency, reduces the visibility of intermodulation products between the two carriers.
18.
Resonant antennas usually use a linear conductor ( or " element " ), or pair of such elements, each of which is about a quarter of the wavelength in length ( an odd multiple of quarter wavelengths will also be resonant ).
19.
The product of " every odd multiple of the product of pi and the imaginary unit plus the natural log of the absolute value of the surd-conjugate of the golden ratio " and the negative multiplicative inverse of the natural log of 2

:: : : OTOH \ sqrt7 and \ sqrt19 are each close to an odd multiple of 1 / 14, so almost as far away from a multiple of 1 / 7 as you can get . talk ) 09 : 29, 27 March 2013 ( UTC)
