23 centimeter tape
The 23-centimeter band is the frequency range from 1.240 GHz to 1.300 GHz . It is in the microwave spectrum . The name is derived from the approximate wavelength of this frequency range. This is why this frequency band is also known as the 24 centimeter band .
23 centimeter amateur band
On July 14, 2017, a Troposcatter - SSB connection was established as a range record over 2662 km between south-west England and Gran Canaria .
