Indication:
the wavelength and the band code character is indicated;
In the case where two bands should be encoded, these should be separated by a comma.
Unit : m
resolution: 0.01 m
Format:
V.VV-B
V.VV-B,V.VV-B
'VV.VV' encodes the value of wavelength.
'B' encodes the band;
each separated by a hyphen ('-')
Example:
the radar transponder beacon wavelength '3cm (X) - Band' is indicated as '0.03-X'
Remarks:
The attribute 'radar transponder beacon wavelength' encodes the specific wavelength at which
a radar
transponder beacon transmits.
Radar transponder beacons generally work on the following wavelengths:
- 3cm (X) - Band
- 10cm (S) - Band
Nevertheless, wavelengths outside the marine band are used.
