What does 2 meter band mean?
The term 2 Meters commonly refers to a frequency band assigned for Amateur Radio use.
It means that the radio waves transmitted at 144 million times per second (MHz) are 2 meters in length.
See Wavelength for more information.
Frequencies in and near this range are also referred to as VHF-High Band..
How far can VHF transmit?
Transmission power ranges between 1 and 25 watts, giving a maximum range of up to about 60 nautical miles (111 km) between aerials mounted on tall ships and hills, and 5 nautical miles (9 km; 6 mi) between aerials mounted on small boats at sea level.
Is 70cm better than 2m?
2m- Good all around band for talking/chatting, but since its VHF, signal travel depends on what’s in its way and the power output of the radio. 70cm- Good band, since its UHF its good to have in the city or around tall buildings or inside of buildings because its wavelength penetrates obstacles better.
How long is a 2 meter antenna?
about 19 inchesGround plane antennas are easy to recognize by their appearance. First off you’ll notice the radiating element. This element is 1/4 wavelength long, or about 19 inches for the 2 meter band.
How long is 2 meters example?
2 Meters = 6.5616798 Feet. A meter, or metre, is the fundamental unit of length in the metric system, from which all other length units are based. It is equal to 100 centimetres, 1/1000th of a kilometre, or about 39.37 inches. A foot is a unit of length equal to exactly 12 inches or 0.3048 meters.

What travels farther VHF or UHF?
VHF frequencies can penetrate objects better than UHF. VHF can also travel farther. If a VHF wave and a UHF wave were transmitted over an area without barriers, the VHF wave would travel almost twice as far. … Remember, UHF signals are shorter than VHF, this is important when you’re in or around buildings.

What is the most popular ham band?
20 meters – 14.0–14.35 MHz – Considered the most popular DX band; usually most popular during daytime. QRP operators recognize 14.060 MHz as their primary calling frequency in that band.
How do I call CQ?
To start a contact, call “CQ” or answer someonecalling CQ. A CQ is a general call to get a random contact. Before calling CQ, listen to find a frequency that unoccupied by any other station.
What is the 70cm calling frequency?
For new hams who are likely to get started in local VHF/UHF operation, the national calling frequencies to be concerned with are 2m and 70cm FM simplex (non-repeater). These are 146.520MHz and 446.000MHz, respectively, and should be included in your radio’s scanned channels.
What is the 10 meter calling frequency?
The 10-meter band is a portion of the shortwave radio spectrum internationally allocated to amateur radio and amateur satellite use on a primary basis. The band consists of frequencies stretching from 28.000 to 29.700 MHz.
What does 10 meter CB mean?
10 Meter Radios are Amateur Radios, also known as Ham Radios. … The 10 Meter Band consists of frequencies stretching from 28.000 to 29.700 MHz. This means that you can still use a standard CB antenna- just be sure to get an antenna that has a power rating that will handle the power output of your 10 meter radio.
Is 2 meters UHF or VHF?
The 2-meter amateur radio band is a portion of the VHF radio spectrum, comprising frequencies stretching from 144 MHz to 148 MHz in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and …

How far can you talk on a ham radio?
Even though Ham radio has more inherent range than other options like the FRS walkie talkies, the popular 2m and 70 cm bands available to Technician-level Hams are generally limited to line-of-horizon or line-of-sight range. If you’re using a handheld unit, you may only get 1-2 miles.
Why is it called ham radio?
Ham radio is a popular term for amateur radio, derived from “ham” as an informal name for an amateur radio operator. The use first appeared in the United States during the opening decade of the 20th century—for example, in 1909, Robert A.
What band is 70cm?
The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.
Why are Baofeng radios so cheap?
One of the reasons the Baofeng UV-5R radios may be so inexpensive is they are not aimed at a specific Niche, therefore they save money on big advertisements and promotions like the ham radio equipment manufacturers like Yaesu Icom and kenwood. They also do not test and advance any technology.
Can a ham radio be traced?
