If you have 12 radios that are each 6 inches long and you line them up on a table, the total length would be calculated by multiplying the number of radios by the length of each radio. So, 12 radios × 6 inches per radio equals 72 inches. Therefore, the table needs to be at least 72 inches long to accommodate all the radios lined up.
unlimited most radio supply outfits will provide an antenna mast to 78 inches, but you can get your machine shop to make a longer mast for a few $$$ extra
The ideal length for an AM radio antenna is typically around 1/4 of the wavelength of the radio waves being received, which is approximately 100 to 300 meters.
(The power of the radio transmitter) times (the length of time it continues to transmit)
Radio waves have the longest wavelength among the electromagnetic spectrum, ranging from several meters to kilometers in length.

Bear in mind that different radio stations have different formats, and not all radio programmers require the same length for the songs that they play, but that said, radio songs are typically not more than 3 minutes in length.
A digital wave length emits a constant signal that quickly declines when out of range (XTS3000 portable radio) An analog wave length gradually declines when out of range (GTX radio)
The formula to calculate the length of an antenna is: Length (in meters) = (Speed of Light / Frequency) / 2. Plugging in the values for radio waves at 300 Hz: we get Length = (299,792,458 m/s / 300 Hz) / 2 = 499,654.43 meters.
Radio waves are the electromagnetic waves with longest wavelength.
It depends on the media (radio, television) and length of time.
