The C&T RF Antennas Inc’s Rubber duck antennas can be connected directly to the wireless device or alternately attached to a magnetic base, which can be mounted vertically or horizontally on any metal surface. The base is then connected to the device with an extension cable.

The C&T RF Antennas Inc provides a variety of antenna styles and types to suit the most varied applications. All include a low-noise amplifier (LNA) to provide sensitive performance in the toughest environments (40° to +65° C with high humidity). And all feature famous Trimble quality and reliability gained from nearly two decades of supplying RF antennas for commercial and military requirements.

The Lora 915 Mhz is a half-wave dipole antenna ideal for 915 MHz terminals and devices that require a ground plane independent antenna
This is a 915 MHz half-wave dipole antenna and ground plane independent, designed for ISM-Band terminals and devices that do not have a ground plane or metal surface on which to mount a 1/4 wave antenna.

Housed in a durable sheath, the 915MHz rubber duck antenna has a U.FL connector that allows the antenna to operate in a horizontal or vertical position. This makes it suitable for portable devices where the orientation of the product is subject to change or is not known.

With a VSWR of less than 2:1 and a gain of 2 dBi, the 915MHz is an effective antenna solution for a range of 915 MHz ISM band applications.

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.

ISM antenna Solution 

ISM bands were originally allocated for the industrial, scientific and medical purpose. Typical applications include a large range of machine-to-machine RF systems. 
C&T RF Antennas Inc offers easy-to-implement standard antennas for all the most important ISM bands.
C&T RF Antennas Inc PCB antennas for ISM applications offer very small size without compromising RF performance. This combined with the inherent immunity of ceramic antennas to other radiators and the hand effect makes them extremely desirable solutions for small hand-held devices.
The helical antennas offer extreme performance for free-space applications.

Narrowband IoT (NB-IoT) is a Low Power Wide Area Network (LPWAN) radio technology standard developed by 3GPP to enable a wide range of cellular devices and services. The specification was frozen in 3GPP Release 13 (LTE Advanced Pro), in June 2016. Other 3GPP IoT technologies include eMTC (enhanced Machine-Type Communication) and EC-GSM-IoT.

NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and high connection density. NB-IoT uses a subset of the LTE standard but limits the bandwidth to a single narrow-band of 200kHz. It uses OFDM modulation for downlink communication and SC-FDMA for uplink communications.

What is the purpose of an antenna?
An antenna is used to convert electric energy into radio waves which enable communication/ instruction between two points. These are usually a radio transmitter and receiver- no radio device will work without one. Depending on the application, antennas can sometimes be as simple as a piece of wire. They work when radio waves reach an antenna and cause the electrons inside it to vibrate. This creates an electric current that duplicates the original signal.

What is the Gain?
Gain is a key performance indicator which combines an antenna’s directivity and electrical efficiency. Gain describes how well the antenna converts input power into radio waves headed in a specified direction or vice versa. Essentially, it refers to how well the antenna works to receive or transmit a signal compared to if you didn’t have one.
Gain is measured in Decibels (dBi) and the larger the dBi, the more gain it has. High gain antennas are useful for manipulating the signal to go further in one direction and less in another but do not increase the signal strength overall. For example, using a high gain antenna on your wifi router would improve the signal reach on the floor it’s on, but rooms on other floors of the house are likely to have some trouble connecting to the internet.

What Types of Antenna Are There?
These are some basic antenna types that can be used for a variety of applications, along with some basic characteristics:
C&T RF antennas Inc stocks a wide range of antenna that can be used for a myriad of applications, including some of those listed above. Take a look at the antennas section of our website for full information, or do not hesitate to send us the inquiry email to
