Antenna Mounting Options

Antennas are available in a variety of packages to suit different applications such as antennas for vehicles, portable equipment, outdoors or vandal resistant. Each type of antenna is constructed to suit the environment with low profile, weatherproof, small form-factor or high gain versions.

  • PCB Antennas

    PCB antennas are designed to be fitted in portable equipment or where space is a premium.Sequoia offer embedded PCB antennas to suit most frequencies and technologies including GSM/3G/GPRS/Bluetooth/WiFi and ISM bands.

    Quad Band GSM / GPRS / 3G  PCB antenna GSM/GPRS/3G/2.4 PCB Antenna 18x18mmGPS 26dB PCB mount antenna 24x19mm, 26dB GPS PCB antenna, 150mm cable, uFL connector Echo 5 GPS PCB antenna, 18dB 15x15mm 
  • Vandal resistant Antennas

    Vandal resistant antennas a highly durable designs typically with low profile and rugged construction. These antennas usually have through-hole mounting with sturdy bolt to hold the antenna in place. Their low-profile design and rounded edges make them very difficult to remove or break. These are typically used for applications where the antenna may be visible and succeptable to malicious or accidental damage Most frequencies are available in vandal resistant antennas. Additionaly mast antenna types are available as 2 or 3 in one antennas for, typically, GSM, WiFi + GPS antennas in one package.

  • Adhesive fixing antennas

    Adhesive antennas are easy to fit to existing equipment and we have adhesive antennas for most frequencies and technologies. The adhesive antennas are very flat and take up little space and area ideal where you don't want to draw attention to the antenna. These are suitable for external or internal to the electronics box solutions so they lend themselves to be hidden from view. Additionally, many of these antenna types are available in IP67 capability for true outdoor waterproof use.

  • Magnetic mount antennas

    Magnetic mount antennas are quickly and easily installed and removed as required. Typically used for vehicles, the also see use in industrial applications for GSM/GPRS/3G.

  • Combined Antennas

    Combined antennas operate with more than one technology e.g. combined GPS and GPRS or combined GPS and 3G where the application requires both data transmission and positioning via GPS. Other options combine GSM and WifI all in one antenna package. 2 or 3 antennas in one package are commonly availabel and have many customers.

    Vandal Resistant, low profile GSM/GPRS/3G antenna GSM/GPRS/3G & 2.4GHz low profile, thru-hole antenna - END OF LIFE  IP60 Rated GSM/GPRS & 3G through hole mount antenna  20/26dB gain GPS Through-hole, body mount antenna Combined GSM/GPS low profile, through-hole, waterproof antenna 

Wifi Antennas / Bluetooth Antennas

Sharing the 2.4GHz frequency band, antennas designed for WiFi will work equally well for Bluetooth wireless devices. Our WiFi range of antennas is now very comprehensive for anyone coverting their products to encompass WiFi connectivity. Discrete internal antennas through to high gain swivel types are all available from Siretta.

GPRS and 3G Antennas

For M2M connectivity over wireless networks using 2G GPRS or 3G networks, Sequoia's GSM antennas are widely used by systems installers and product developers.

Antennas Terminology

  • Voltage Standing Wave Ratio (VSWR)
    The values of VSWR will be greater than or equal to 1. For optimum transmission the VSWR value should be as close to 1 as possible. Higher values mean than there is a loss of signal due to mismatch between source and antenna. If the antenna is mismatched to the source then it will reflect a percentage of the transmitted power back to the source which causes interference and potential degradation of signal.
  • Frequency
    Antennas are designed to work at specific frequencies. e.g. for Wifi/Bluetooth the centre frequency is 2.4GHz and antennas designed for WiFi and Bluetoth are optimised for this frequency. If a wifi antenna is used for a difference frequency e.g. 868MHz then its performance will be significantly below normal.
  • Omni Directional Antennas
    Omni directional antennas radiate in all directions and therefore are used where the location of the receiving station is not known.
  • Directional Antenna
    A directional antenna as its name suggests will provide maximum signal transmission across a narrow cone from the antenna. Directional antennas are used where the direction of the receiving station is known.
