What is a 433MHz High Gain Antenna Helical Antenna?
The 433MHz High Gain Antenna Best RF Antenna CTRF-ANTENNA-SP-0433-7804 is a 5dBi 433MHz High Gain Antenna helical antenna with a length of 78×4.3mm size spring antenna manufactured by C&T RF Antennas Inc.
The Spring Antenna Matches With 433mhz Lora Breakouts, Bonnets, And Feathers. They’re Made Of Copper Wire So You Can Solder Them Easily.
A spring antenna is a metal coil that is typically installed between the mount and the antenna itself.
Springs are added to antennas to provide stress relief to both the antenna and the antenna mount in wind and in situations when obstacles such as tree limbs are likely to be struck by the antenna.
The 433MHz High Gain Antenna Best RF Antenna spring antenna CTRF-ANTENNA-SP-0433-7804 matches great with any of our 433MHz RFM and LoRa breakouts, bonnets, and Feathers. They’re made of copper-clad wire so you can solder them easily.

How to choose a spring antenna?
1. Spring antenna selection skills
Spring antennas can be divided into nickel-plated, gold-plated, and copper spring antennas according to their materials.
According to the frequency, there are generally 315/490/868/915MHz/2.4G/5G/3G/GSM/4G/LTE/Lora/ISM/PCS/NB-IoT spring antennas.
Selection skills:
When choosing a spring antenna, you can see its size, length, gain, impedance, material, frequency, standing wave ratio, and other parameters according to actual project requirements.
2. Rubber ducky antenna selection skills
According to the connection method of the antenna head, the rubber ducky antenna can be divided into a straight rubber ducky antenna, elbow rubber ducky antenna, and folded rubber ducky antenna;
Classified by material: gold-plated and nickel-plated rod antennas.
Selection skills:
According to the module frequency used in the project, select the rod antenna of the corresponding frequency, and pay attention to whether the length of the rod antenna, the connection method of the antenna head, the material, the gain, the impedance, the standing wave ratio, etc. match.
3. Tips for selecting a magnetic mount sucker antenna
The frequency can be divided into 315/433/490/868/915MHz sucker antenna, 2.4G Wifi sucker antenna, 5G Wifi sucker antenna, 4G LTE sucker antenna, and 3G GSM sucker antenna.
Selection skills:
If the power of the module is more than 2W, it is recommended to choose a magnetic mount sucker antenna, and whether the project is waterproof, consider the cable length, input impedance, standing wave ratio, gain, suction cup size, and other parameters.
C&T RF Antennas Inc. supplies the spring antenna coil helical antenna with 315 Mhz, 433 Mhz, 868 Mhz, 915 Mhz, Wi-Fi, GSM, etc.
