ANT-8/9-SPS1-1

## **ANT-8/9-SPS1 Series Panel Mount 868/915 MHz LPWA Antenna** 

The ANT-8/9-SPS1 antenna is an external panel mount puck-style multiband antenna designed for use in 868 MHz and 915 MHz frequency bands for low-power, wide-area (LPWA) applications such as LoRaWAN®, Sigfox® and WiFi HaLow™ as well as ISM and remote control applications.

## **VSWR** 

Figure 2 provides the voltage standing wave ratio (VSWR) across the antenna bandwidth. VSWR describes the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency. Reflected power is also shown on the right-side vertical axis as a gauge of the percentage of transmitter power reflected back from the antenna.

## **RETURN LOSS** 

Return loss (Figure 3), represents the loss in power at the antenna due to reflected signals. Like VSWR, a lower return loss value indicates better antenna performance at a given frequency.

## **PEAK GAIN** 

The peak gain across the antenna bandwidth is shown in Figure 4. Peak gain represents the maximum antenna input power concentration across 3-dimensional space, and therefore peak performance, at a given frequency, but does not consider any directionality in the gain pattern.

## **RADIATION EFFICIENCY** 

Radiation efficiency (Figure 6), shows the ratio of power delivered to the antenna relative to the power radiated at the antenna, expressed as a percentage, where a higher percentage indicates better performance at a given frequency.

## **RADIATION PATTERNS** 

Radiation patterns provide information about the directionality and 3-dimensional gain performance of the antenna by plotting gain at specific frequencies in three orthogonal planes. Antenna radiation patterns (Figure 7), are shown using polar plots covering 360 degrees. The antenna graphic above the plots provides reference to the plane of the column of plots below it. Note: when viewed with typical PDF viewing software, zooming into radiation patterns is possible to reveal fine detail.

## **ANTENNA MOUNTING** 

The ANT-8/9-SPS1 antenna is an externally mounted multiband antenna that can be permanently installed onto metallic and non-metallic surfaces up to 3.9 mm (0.15 in) thick when used with the provided boot, and up to 4.2 mm (0.17 in) without the boot. Use of the boot is optional, and is intended to reduce the potential for marring of the mounting surface. 

The antenna terminates in a M12x1 threaded shaft and is provided with a washer and hex nut. The mounting hole dimensions are shown in Figure 8.
