What is the 160-meter band used for?
160-meter band refers to the band of radio frequencies between 1.8 and 2 MHz, just above the medium wave broadcast band. For many decades the lowest radio frequency band allocated for use by amateur radio, before the adoption, at the beginning of the 21st century in most countries, of the 630- and 2200-meter bands.

What frequency is 160 meter band?
between 1.8 and 2 MHz
160-meter band refers to the band of radio frequencies between 1.8 and 2 MHz, just above the medium wave broadcast band.
How long is 160 m dipole?
Simple Transmitting Antennas As stated in the introduction to this article, the first biggest challenge for operating on 160m is the physical size of an efficient transmitting antenna. The length of a half wavelength dipole at 1.85 MHz is approximately 253 feet (each side would be about 127 feet).
What is top band amateur radio?
1.810 – 2.00 MHz Also known as ‘top band’, the 160m band is usually grouped in with the HF bands and is the lowest frequency band commonly in use by HF operators (although it is actually an MF band).
How long is a 160 meter end fed antenna?
The unique design characteristics of this 60 foot long 10-160 Meter HF antenna enables it to approach resonance on the major HF bands (10/12/15/17/20/40/80 Meters). You can even use an external tuner to match 160 meters.
What does HF mean in ham radio?
High frequency
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).
How long is a 160 meter dipole?
As stated in the introduction to this article, the first biggest challenge for operating on 160m is the physical size of an efficient transmitting antenna. The length of a half wavelength dipole at 1.85 MHz is approximately 253 feet (each side would be about 127 feet).
Why do most amateur stations use lower sideband on the 160 meter 75 meter and 40 meter bands?
To make communications consistent and to keep bandwidths to a minimum, the convention is to use lower sideband (LSB) communications for the longer wavelength (lower frequency) bands at 160, 75, and 40 meters.
