What is stirrups in civil engineering?
helical reinforcement
What is a reconfigurable antenna?

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.
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.
