Poynting XPOL-2-5G Antenna

Product Information

Cross polarisation limits how out of phase with any antenna in the system a received signal can be. This minimises the maximum loss in signal strength a system can experience (at least, as a result of polarisation shifts). There are three types of antenna polarisation: linear, circular and elliptical. Practically, linear polarisation is the most pertinent for most fixed wireless access applications and can be subdivided into horizontal and vertical polarisations. The Poynting XPOL-2-5G Outdoor 4G/5G LTE 11 dBi Cross Polarised Directional Panel Antenna is Poynting’s third generation "V3" of this Cross Polarised (XPOL), cellular band, 2x2 MIMO antenna. The antenna enclosure effectively looks the same as the second generation "V2", but has been completely redesigned on the inside. Poynting have used advanced metamaterial technology, making use of Artificial Magnetic Conductors (AMC) and new registered/patent pending radiator configuration, which is proving to yield exceptional improvements in bandwidth and gain. Radiation patterns of this antenna are exceptionally well controlled, further adding to the performance of the antenna. Key Features

However, if we hold the gain-by-frequency diagrams side by side, we see that the gain in the 980-1710MHz band (not formally served) is actually extremely stable vs that of the XPOL-2-5G (where it is far more variable). The XPOL-16, by contrast, aims to serve those same 2G GSM and 3G frequencies, as well as the 4G/LTE frequencies at the lower end of the spectrum, including 450-470MHz and 790-860MHz. Again, this antenna aims to provide exceptionally consistent gain values across its more specialised range of frequencies. Cross polarisation is a type of diversity technique capable of minimising signal loss within a cellular network by handling polarisation shifts. Learn what that means here! Home Blog Antennas This antenna is cost-effective and small, making it an affordable way to drastically boost performance on a 4G or 5G cellular network. When the signal polarisation is out of sync with that of the antenna, the antenna can’t receive the signal at full strength. In fact, reception is so impaired that an observer would see signal loss of up to -34dB.For example, a vertically polarised signal can, by the time it reaches a receiving antenna, become horizontally polarised. A VSWR of 1.22 (the Bluespot 5G Mini) means approx. 96% efficiency at turning electrical signals into radio waves @ 3600MHz. A VSWR of 1.75 (the Poynting XPOL-1 @ 3600MHz) equates to 66% efficiency (speaking very loosely; other factors matter too). See https://www.everythingrf.com/rf-calculators/vswr-calculator.

If you have line of sight to the cell tower the XPOL-2 is a great choice of directional antnena. If you are unsure as to where the cell tower is then the omni-directional XPOL-1 is a great alternative to consider. New to the Poynting lineup of cross polarised antennas, the EPNT-1 and EPNT-2 offer omni- and uni-directional solutions (respectively) for minimising the length of coaxial cable used in the system. The antenna ships with a fixed attachment of 5m of HDF195 5mm coaxial cable, which experiences signal loss at around 0.6dB per metre at 2600MHz (a viable higher frequency for 4G/LTE). With 3dBi of peak gain at this frequency, this sets the net gain on the system to 0dB. Two Poynting XPOL units can be combined into powerful 4x4 MIMO applications for even greater performance benefits. Both 2x2 and 4x4 MIMO variants of the XPOL-1-5G are available, so customers looking for ultimate stability and throughput should opt for the 4x4 MIMO model.

Reviews

The XPOL-1 isn't so great on the higher 5G frequency band - it really only goes to about 3500MHz, looking at their datasheet ( https://poynting.tech/wp-content/up...es/Technical-Specification-A-XPOL-0001-V2.pdf) . Typically a VSWR of <1.5 is the cutoff. The XPOL-2-5Gis Poynting’s third generation “V3” of this very popular Cross Polarised (XPOL), cellular band, 2x2 MIMO antenna. The antenna enclosure effectively looks the same as the second generation “V2” but has been completely redesigned on the inside. The XPOL 5G series of antennas are the most relevant to the U.S. market, and also to 5G future-proofing. But first, what is cross polarisation and why would you want it in your antennas? What is Cross Polarisation (XPOL)? Diversity Techniques The Poynting XPOL-1 is an omnidirectional antenna. This means that it can efficiently receive and distribute radio frequencies (RF) in all directions, making it especially well suited for those applications where the direction of the nearest base station is unknown, or in those urban applications where a direct line-of-sight to any one base station is unlikely.
