High Precision Copper Antenna Wire Forming Spring For Precision Parts
In the field of wireless communication, the spring antenna plays a very important role and is often used with the wireless module in many projects.
First, the role of the spring antenna
Spring antenna is a very important part in wireless communication.
Its function is to radiate and receive radio waves. When
transmitted, high-frequency current is converted into
electromagnetic waves; When received, the electromagnetic waves are
converted into high-frequency current. In simple terms, it is
receiving the transmitting signal.
Two, spring antenna classification
1, according to the frequency classification: 315MHz spring
antenna, 433MHz spring antenna, 868/915mhz spring antenna,
470/490mhz spring antenna.
2, according to the material classification: gold-plated spring
antenna, copper spring antenna, nickel plating spring antenna.
Three, what are the advantages and disadvantages of the spring
antenna
Advantages: the cost of spring antenna is relatively low compared
with other antennas, and the size is small, easy to install, the
antenna standing wave ratio performance is good, has a good
anti-vibration anti-aging ability. The wireless module and antenna
can be used together to make the wireless transmission distance
longer.
Disadvantages: its gain is relatively small, and not waterproof,
generally used as a built-in antenna.
General wireless modules use antennas: spring antenna, rod antenna,
sucker antenna, sucker antenna is relatively more expensive than
spring and rod antenna. When choosing the antenna, we mainly look
at the frequency, gain, impedance, standing wave ratio, material,
size and other parameters are in line with their needs.

1. Should I use a spring on CB antenna?
A spring is beneficial for most CB antennas, provided you are using
a good, conductive spring of the correct size for your antenna. You
should definitely add a spring if there is a chance your antenna
will strike limbs or other obstacles, or when you need to add
length to an antenna for SWR improvement.
2. What does an antenna spring do?
very antenna should have a spring to protect the antenna, mount and
vehicle. These springs are made from long-lasting, top-grade
electro-polished stainless steel.
3. Will a CB radio work without an antenna?
CB Antenna - Without an antenna, your radio is useless! Don't
forget this key component. CB Antenna Mount - You'll need a mount
of some sort to attach the antenna to your vehicle. If you'll be
using a magnet, roof or trunk-lip antenna, you won't need to worry
about this as the antenna base doubles as the antenna mount.
4. How does a whip antenna work?
The whip antenna is a monopole antenna, and like a vertical dipole
has an omnidirectional radiation pattern, radiating equal radio
power in all azimuthal directions (perpendicular to the antenna's
axis), with the radiated power falling off with elevation angle to
zero on the antenna's axis.
