What is 70cm band Good For?
Amateurs predominately use the band for FM or digital voice communications through repeaters (useful for emergency communications), as well narrow band modes (analog and digital) for long distance communications (called “DX”, including Moonbounce). The band is also popular for Amateur Satellite Service.
What is PL259?
PL-259 Connectors, Adapters & Reducers for Ham Radio Applications. The PL-259 is also known as a UHF connector with the common male/female variants. The male UHF PL259 is the most common connector used to interconnect equipment and antennas in ham shacks.
What’s better 2m or 70cm?
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.
Which has better range 2m or 70cm?
2m can pass around trees, leaves and other such foliage easier than 70cm which makes it good for rural settings, but 70cm is better if you’re in a place with lots of buildings since it can pass through doorways and windows easier.
Is 2 meter band a plan?
Notes: The frequency 146.40 MHz is used in some areas as a repeater input. This band plan has been proposed by the ARRL VHF-UHF Advisory Committee….2 Meters (144-148 MHz)

What kind of antenna do I need for a two meter radio?
The article consist of two version of a 12.5 Ohm 3 elements yagi beam antenna plans for the two meter band, a full sized and a shortened version expecially designed for the SSB and CW on 144 MHz. 3 elements VHF yagi antenna – 3 elements VHF Yagi homebrew antenna designed with YAGIMAX 3.
What kind of band Plan do I need for 2 meters?
Thus, it makes sense to have a band plan that divides the band up into segments for each type of operation. 2 Meter Band Plan As shown in the table, the ARRL 2 Meter amateur band plan supports a wide variety of radio operation. Large portions of the band are dedicated to FM operation, consistent with the popularity of the FM mode.
How big is an antenna for 144 MHz?

What is the impedance of a 2 meter antenna?
2m Quad Turnstile Antenna – The loops are made of 10 mm round aluminum tube. No bending pliers was used to gently bend 90 degrees to obtain a square with 53 cm inner sides. Each loop has an impedance of approximately 100 Ohm.
