What is the history of helical antenna?
Helical antennas were first proposed by the American engineer John D. Kraus in the early 1950s. They gained popularity due to their compact size and wide bandwidth, making them suitable for various applications, including satellite communication and space exploration. The design features a helical element that radiates electromagnetic waves in a circularly polarized fashion, which was particularly advantageous for receiving signals from satellites in motion. Over the years, helical antennas have undergone various improvements, but their fundamental design principles have remained largely unchanged.
Formula module in helical gear?
the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth the module of a helical gear is calculated in the same way of that of a spur gear: module=pitch diameter / no of teeth
What is stirrups in civil engineering?
helical reinforcement
What is the difference between helical gear and screw?
Spur gears have straight teeth while helical gears have curved teeth. Generally, helical gears are usually quieter and smoother in operation, while spur gears are easier to make and much less expensive.Helical gears are stronger than spur gears.
Can you replace an XM radio antenna with any other antenna like a 3ft hard cb antenna?
You can replace an XM radio antenna with a CB antenna, a ham 40-meter mobile antenna, a cellphone antenna, a GPS antenna, a TV antenna, a wire coat hanger, a 6 GHz microwave antenna, or a chain of paperclips. However, since none of them is optimized to operate at the frequencies of XM radio, like the XM antenna is, none of the others will work as well. Most of them will likely be so inefficient at the satellite radio frequencies that when you use one of those, you hear nothing at all on your radio.
Where helical antenna is used?
it is used in space
A helical antenna is made up of coil and what?
plane reflector
What is the use of ground plane in helical antenna?
A ground plane in a helical antenna acts as a reflector, enhancing the radiation pattern and efficiency of the antenna. It helps to direct the radiated signal in a desired direction and minimizes signal loss due to ground reflections. The ground plane also provides a stable reference point for the antenna structure.
What are the disadvantages of helical antenna?
Efficiency drops with added turns. Maximum efficiency is about 80% with a 3-4 turn helical and drops to about 60% at 12 turns.

What is the advantage of a helical wire satellite antenna?
Circular polarization characteristics of a helical antenna help offset the effects of spin modulation from satellites in motion, that is, the tendency for satellites to spin causing the position of their antennae to change rapidly in accordance with the spin, causing a fluctuation in the signal as received by a fixed signal on earth. Circular polarization of the earth fixed antenna reduces the fluctuating effects of the satellite's spin on the recived signal.
Where is the radio antenna located on a 2000 Lincoln Navigator I have no reception but all other features work?
the antenna is in the right rear side glass.
What is frank dance s helical model of communication?

What is Helical Sequence?
helical sequence
What is the meaning of helical?
Of or pertaining to, or in the form of, a helix; spiral; as, a helical staircase; a helical spring.
What is Antenna hopping what are the Features Which type of cabinet can accept hopping?
In antenna hopping the transmit antenna is changed during the interleaving period resulting in an increased channel diversity which can be converted into a performance gain through the channel coding.
