433MHz | 868MHz Antenna

This range has been designed as a cost-effective antenna to provide longer range coverage for 433 | 868MHz ISM band applications. The omnidirectional radiation pattern allows the antenna to be quickly installed. This antennas provides an ideal solution for infill coverage, or to improve gain for a subscriber installation. Optional wall or bracket mount.

Antenna comes with 5m cable and SMA connector and provides 2dBi gain.

Lora (Long Range) is a patented digital wireless data communication technology developed by Cycleo of Grenoble, France, and acquired by Semtech in 2012. Lora uses license-free sub-gigahertz radio frequency bands like 169 MHz, 433 MHz, 868 MHz (Europe) and 915 MHz (North America). Lora enables very-long-range transmissions (more than 10 km in rural areas) with low power consumption. The technology is presented in two parts — Lora, the physical layer and LoRaWAN (Long Range Wide Area Network), the upper layers.

Lora and LoRaWAN permit inexpensive, long-range connectivity for the Internet of Things (IoT) devices in rural, remote and offshore industries. They are typically used in mining, natural resource management, renewable energy, transcontinental logistics, and supply chain management.

RF Antenna knowledge

1. Antenna Gain

Gain is one of the most important parameters of the antenna system, the definition of antenna gain and omnidirectional antenna or half-wave dipole antenna related. Omnidirectional radiation is assumed that in all directions and radiation power of the radiator, the antenna gain in a given direction is the field strength in that direction.

2. The antenna input interface

In order to improve the reliability of passive intermodulation and RF connector, enter the base station antenna interface using 7/16DIN-Female, before the antenna is used, the port should cover, so as not to form oxides or entering impurities.

3. Antenna size and weight

In order to facilitate antenna storage, transportation, installation, and safety, to meet the electrical indicators, the antenna dimensions should be as small as lightweight as possible.

4. Wind loads

The base station antennas are usually mounted on tall buildings and towers, especially in coastal areas, the annual wind speed and requires the antenna work at 36m / s when without destroying the 55m / s when.

5. The working temperature and humidity

The base station antenna should be at ambient temperature -40 ℃ - + work within a range of 65 ℃. The base station antenna relative humidity should be within the range of 0-100% of a normal working environment.
