LoRa LPWAN IoT Antennas

LoRa LPWAN IoT Antennas four hot products

LoRa LPWAN IoT Antennas are a hot topic right now and building out a reliable network based on 868 MHz or 915 MHz requires the deployment of quality antennas and accessories. Here we look at four robust antenna types to facilitate consistent and dependable installation.

High gain outdoor omni-directional antenna

On the edges of the network where signal strength cannot always be depended on, a quality outdoor antenna is often a go to solution. Common requirements for such antennna are be robust with the antenna and bracket built from quality components, offer high gain (5 dBi+) to provide a stable signal, be compact enough to be discreet and offer flexible mounting options. Combining these factors will deliver consistent performance whatever the climate conditions. A fine example of such an antenna is the WMO86916.

Wall-mount omni-directional antenna

Some external LoRA LPWAN IoT antennas are required because the antenna cannot, for one reason or another, be mounted directly onto the radio. For reasons of signal coverage, location of radio/terminal below ground or in a shielded area, willful damage or simply practicality, wall-mounted omni-directional antennas are often used. For most applications they need to be compact, discreet and cost-effective while offering robust RF performance. They also need to be easy to install in order to keep installation costs/time to minimum. Two excellent choices of such antennas are the Wall-Blade and the WCO-868-WMB. Both are very compact, easy to install and offer accomplished RF performance.

Low profile permanent mount puck antenna

Antennas are often required to mount directly onto a terminal or enclosure. Mostly permanently mounted by a threaded boss through which the cable is fed, they offer a secure and effective way to facilitate 868 MHz and 915 MHz communications. Such antennas need to be very compact with a durable radome, be of a material to withstand inclement weather, possess a durable mounting stud and offer reliable RF performance. Many of the small pucks, smaller means that they less likely to draw attention to themselves, are groundplane dependent i.e. they have to be mounted onto a metal surface. One such antenna is the Button 868 915 MHz antenna. This antenna is compact as it gets without compromising on RF performance.

Terminal/Radio-mounted dipole antenna

In cases where the antenna does not need to be mounted away from the radio or terminal, a dipole antenna can offer reliable RF performance when directly connected via a coaxial connector. This type of antenna is not the smallest, you can find small 1/4 wave antennas that are much more discreet, but they typically offer robust RF capabilities. Especially where no groundplane is available, for example if the terminal has a non-metal enclosure, the dipole style antenna can offer RF advantages over rival terminal antennas. In addition, do verify the build quality of such antenna so that you can be assured that it is built to last as inferior antennas can be very easily damaged thereby demanding costly engineer revisits. A good example of a quality dipole antenna is the BKR915 and the BKR868.

Aside from the antennas, it is wise to make sure that if you are running coaxial extension cables you use quality cables to minimise cable losses. At 868 MHz and 915 MHz for cable runs up to 10M, you could typically use RF195 type cable. From 10-20M it would be worth considering RF240. And for longer RF400 cable installations. Using inferior coaxial cable will negate the benefits of use quality antennas as signal losses across the inferior cables will be experienced.

Some of the antennas mentioned can be purchased via the Connex webshop.

High Gain 915 MHz

High Gain 915 MHz LoRa LPWAN antenna ideal for outdoor installs

A new High Gain 915 MHz outdoor wall-mount omni-directional ideal for LoRA and LPWAN applications has been released by EAD. Offering 5.8 dBi gain at 915 MHz, the WMO86916 is a compact and robust solution. It is supplied with an effective, reversible L-bracket allowing both wall-mount and pole mount capability.

The WMO86916 antenna is supplied with a white low loss 5M cable as standard terminated in a SMA-Male connector. Other connectors such as RP-SMA and RP-TNC are available. The cable length can also be customised from 0.5M to 5M in overall length.

Designed with fringe sites in mind, this high gain 915 MHz antenna is an excellent for ensuring signal continuity. The antenna tube is made out of fibreglass for longevity and with an overall length of just 840mm, the WMO86916 is compact enough to be discreet in many installations. Applications include remote monitoring applications, ultilities, RF mesh networks and unlicensed RF frequency band deployments.

Alternative omni-antennas for 915 MHz are available including the compact Wall-Blade antenna and the WCO-915-WMB antenna.

The WMO86916 also supports 868 MHz with a gain figure of 5.8 dBi.

Low loss RF coaxial cables

Low loss RF coaxial cables – comparing your options

This blog article entry considers the merits of choosing which of various low loss RF coaxial cables to use for IoT, LTE or LORA wireless applications where an external antenna is used to connect to router, gateway or terminal.

In this article, we will consider cables such as RG174, RG58, RF195, RF240 and RF400 as possible coaxial cable choices for your installation.

The first point to consider is that running extension or jumper cables between the antenna and the radio (router, modem, terminal, gateway, wireless device – for the sake of this article we’ll simply use the term radio) is that the cable will always introduce loss into the system. Whether you use very low loss, high quality coaxial cable or very thin and “lossy” cable, attenuation will be introduced between antenna and radio. A key area to focus on is to minimise the loss introduced by the cable in order to maximise the performance of the antenna. On longer cable runs it is very important to use low loss RF coaxial cables otherwise attenuation is too great for a functional wireless deployment.

Looking at RG174, it is a thin coax typically with a PVC sheath and can be used often for lower frequencies up to a very maximum of 2-3 metres. Most often it is used for what we call “pigtail” or adapter cables which a short cables that typically connect a cable to radio often to convert from one connector to another or if a connector presenting to the radio is too small to be fitted to a very low loss coax. (RF400 cables are 10.2mm diameter and as such connectors like MMCX, QMA, MCX cannot be fitted to RF400).

RG58 is a stranded coaxial cable about 5mm in diameter. It can be used for longer runs than RG174, however we typically recommend customers switch to RF195 which is also 5mm in diameter, but due to its solid copper core and superior insulation is lower loss than RG58.

RF195 is typically used in cable runs for 4G and cellular applications up to maximum cable run of 10M. Any more than 10M then the attenuation introduced by the cable into the system starts to affect the overall performance. The advantages of RF195 is that it is cost-effective, flexible and has good RF properties making it ideal for 5M extension cable requirements.

For longer runs that RF195 offers or for lower loss performance over 5 to 10M, then RF240 low loss coaxial cables are an ideal selection. RF240 is very similar to LMR240. With an overall sheath diameter of 6.1mm, it can be offer in a PVC all-purpose sheath or a LSZH (Low Smoke Zero Halogen) CPR Class Eca compliant sheath.  RF240 could be used up to about 15M cable runs for 4G and cellular applications and probably shorter runs if using it for WiFi. Once again, RF240 is cost-effective, but it is also flexible and robust making it ideal in installations where cable routing might be a little tricky.

For even longer cable runs, we have RF400 with PVC sheath for multi-purpose applications and RF400 LSZH Eca cable. These two cables are very low loss and we supply cables runs up to 50 or 60M depending on the frequency used in the installation. Both RF400 low loss RF coaxial cables are approx. 10mm in diameter, offering a little bit of flexibility, but most key is excellent RF properties meaning that you can minimise attenuation from the antenna to radio in your system.
