SMC/BMC Antenna Reflector

High precision, high efficiency, and high gain

The most important job of using bmc reflector for the manufacture of
antennas is to fully exploit its features and achieve high precision in
antenna design from product design and process. Under the condition that the
shrinkage ratio of the material and the SMC molding shrinkage rate have been
considered in the mold size design, the SMC antenna reflective surface has a
smaller shape from the original design paraboloid after molding. That is,
the accuracy of the SMC molded antenna is completely guaranteed by the
accuracy of the mold. The rms value of the SMC antenna molded integral
reflection surface is 0.25 mm, and the rms value of the single-piece
reflection surface of the split antenna is less than 0.3 mm, and the rms
value of the reflective surface after assembly is less than 0.6 mm.

Corrosion Resistance of SMC/BMC Antenna Reflector
Conventional antenna materials such as aluminum plates and steel plates are
made of metal materials, not as good as SMC which as a non-metal dielectric
composite material in terms of acid resistance, alkali, salt, and corrosion
resistance. The Pikington laboratory in the United States used infrared to
analyze the surface of SMC materials and found that its surface is covered
by additives, resin, and very fine calcium acid filler. It has good acid
resistance, water resistance and corrosion resistance. The antenna
reflection made by this material is solved the disadvantage of the
traditional metal material antenna is easy to corrode. In coastal areas,
rainy, humid areas and areas with excessive acid rain, the anti-corrosion
advantages of SMC molded antennas are particularly prominent. The SMC molded
antenna samples were placed in 130 highly corrosive chemical environments at
an ambient temperature of 50 ° C. The results showed that the test samples
showed little or no change.

Long Life SMC/BMC Antenna Reflector
The average aluminum plate antenna is as small as 2-3 years in the coastal
area, and more often 4-6 years, and it will generally be damaged by salt
spray erosion and aging. The most obvious example is the cable TV (CATV) in
Taiwan, which was built earlier than the mainland. It is estimated that
there are nearly 1000 satellite TV receiving antennas on the island, all
built in the mid-1980s, all of which were aluminum plate antennas, until the
early 1990s. , that is, has begun to replace. The service life of SMC molded
antennas is generally more than 15 years; PROMLIN's prototype SMC molded
antennas in 1985 are still working normally, and they are subject to
typhoons and heavy rain every year.

Strong Wind Resistance of SMC/BMC Antenna Reflector

Since the antenna reflection surface is designed during the molding process,
multiple longitudinal and circumferential rib structures are designed.
According to the structural strength calculation, the SMC antenna can
withstand a wind load of 45 m/s, which shows its remarkable structural
rigidity and strength.

Special Reflective Layer Technology of SMC/BMC Antenna Reflector

The reflective surface of the SMC antenna uses a metal aluminum mesh as a
reflective layer of electromagnetic waves. The aluminum mesh in the finished
antenna is evenly embedded under the surface SMC, which can reflect
electromagnetic waves and insulate the atmosphere, and plays a good
protective role.

Good consistency, no deformation, easy to transport and install
Because SMC antenna adopts membrane pressure technology under high
temperature and high pressure. Its material properties and processing
technology determine the unparalleled consistency of SMC antennas with other
antennas. This not only ensures the accuracy and high gain of the antenna,
but also is very easy to install and debug. SMC, commonly known as "glass
reinforced plastic", has the characteristics of no deformation, which
eliminates the adverse effects of antenna deformation on the satellite
receiving system during transportation.

Our bmc compound andbmc composite products have a wide range of
applications: differents of auto parts, different kinds of motors, Battery
box and high voltage box ,building materials, electrical appliances, Energy/
power generation, etc.
