Questions about Poynting XPOL-2-5G-01

The antenna can certainly bring about an (albeit small) improvement, although I have a big question mark over the cost/benefit ratio. Pay particular attention to the "fair use policy": If you use over 60GB/month your speed will be throttled. Digital Republic does not have this, but runs on the sunrise network.

yes, has nothing to do with the supplier. and covers the frequency bands for 4G and 5G/NR

It's not a device, it's just a directional antenna. If you are in Switzerland, you can find the locations of the 5G masts on the geoportal: https://www.bakom.admin.ch/bakom/de/home/frequenzen-antennen/standorte-von-sendeanlagen.html The antenna must then be aligned +/- to this mobile phone mast on the outside of the building (even if you have no direct visual contact) and permanently mounted. It definitely helps with bandwidth and stability. If you really don't have any line of sight and you only have reception at all due to reflections, I would recommend an outdoor omni antenna. The other thing is that not all 5G routers are the same, there are many different frequency bands and routers that do MIMO multiplexing and those that do not. Certain routers can use up to 4 bands simultaneously, etc. But I'm not an expert on this either. The MikroTik Routeur Chateau LTE 5G R16 Wifi ac 5 ports Gigabit can do pretty much everything :-)

Recommendation: ZTE Mc889 with T3000 in a set. I've had the best results with it.

the antenna has 2x SMA connectors, check if your router has these connectors, otherwise you need adapters e.g. to TS-9 Yes, this antenna is also available with a 5m cable, it is model A-XPOL-0002-V3-01

no chance, you have to drill

it is a directional antenna (with cross polarisation)

no

The prices are different mainly due to different sources of supply, as we work with different suppliers and the purchasing conditions differ depending on the supplier. However, please note that these are also versions with different manufacturer numbers XPOL-2-5G-01 and XPOL-2-5G-02. These are listed as Product Options on the manufacturer's website at https://poynting.tech/antennas/xpol-2-5g/. This item is A-XPOL-0002-V3-01, with 5m cable. The other version, A-XPOL-0002-V3-02, should not have a cable included, according to the manufacturer's website.

Buy a bigger cable? Knowing that it will degrade the SNR... otherwise opt for a different product for example from Mikrotik with the router integrated in the antenna to output directly in Ethernet instead of coax.

According to our information, this is 5 m.

If they have different frequencies, is it possible for you to determine via the router which frequencies it is aiming at? It should also be noted that the router software usually chooses the better/stable "connection" and keeps changing if another one is better. This means that not only the signal values are important, it could also be that the antenna with the better signal has more connections and data throughput (use by other users), has more sources of interference, or has less bandwidth (Mhz). This causes the router to automatically aim for a "better" antenna. If you can target the antenna through the frequency, you may then notice through a speed test that it is not better at all.
