Hello. I am faced with the choice of an antenna for Huawei e5377. I am leaning towards the sorensen 17 antenna. I live about 10 km from the LTE transmitter. While looking for antennas, I also found an interesting Signaflex option:
I suspect that the first, like the second, is Chinese. If you want to see how it works, buy it and share your comments. if necessary, give back and buy Sorensen or Cybertech. 10 km is quite far, what operator and town? The second is a little toy and not omni-directional at all. A seller who writes such a description is unreliable (sells soap and jam from China)
If you have dealt with this antenna, give the results of some tests. What is the gain of these antennas in reality with a 10m cable? How does it relate to the theoretically given 2x20dBi radiation angle? Maybe you don't care about its characteristics somewhere.
In most cases, we measure the signal strength with the MDMA program. Parameters tested at the client's a few hours ago:
RSSI: -51 RSRP: -52 RSRQ: -8
BTS at a distance of about 4.5 km. Installation site: Kuźnica (near Nowa Brzeźnica in Silesia)
In this case, it was necessary to strengthen the signal of the Huawei E3272 modem. Previously, UP was within 8 Mb. After connecting the antenna and a few minutes of combination with the setting, it increased to 19 Mb.
Regarding the characteristics and angles, I have sent an inquiry to the seller. As soon as I send them to me, I will post them on the forum.
We did not measure without the antenna. In a few days we will have installations in similar conditions, we will measure it and upload screenshots. There is a forest and a small hill around, so it will be possible to do decent tests.
I have LTE 1800Play 400m for BTS. The router outside sees BTS and follows RSSI-51, RSRQ -59, RSRP -9. Hence my question. I do not believe too much that even on the antenna with a real gain of about -15dBi you can get parameters like yours from a distance of 4.5 km. On the antenna with a real gain of -11dBi from 4 km, without the BTS being visible, I got RSSI -67, RSRP -89, RSRQ -10. Without an antenna, the parameters were about 10-12 dB worse. Who is the manufacturer of this antenna?
We have hits with BTS every now and then. Sometimes the client has a transmitter 300 meters from the house and nothing works, even after connecting the antenna, and sometimes at 3-4 km we connect the usual 19dbi directional and it is enough. It is influenced by a large number of factors. Our one client had a neighbor who was on the line to the BTS and had some homemade generator in the shop running and it was causing a disturbance. From 8:00 a.m. to 4:00 p.m. there was no LTE and in the rest of the time it was It took us a while to discover this.
Regarding the production, the seller says that it is made in Poland. The box has Polish subtitles in full. It's hard to say for sure, but the performance is pretty good. There are no sprues on the housing. The silicone seals the back panel well. Cybant included, screws, etc. There is really nothing to complain about, and we have already reworked these antennas with a lot of Allegro.
We also started selling these antennas directly to customers with our wires and so far nothing has come back.
The performance of the antenna - poor in my opinion. 2-meter thin cable, very delicate handles, brass M5 thread molded into plastic (one I broke). The plastic of both the cable and the antennas is the same as in bad gadgets - a lot of filler, brittle. No fit, not suitable for safe / permanent outdoor installation due to gaps. Connectors are solid and made correctly.
As part of the tests, I connected it to the Huawei B593s router.
Measurements in the picture in the attachment. Bold - these are the most common values. Router and antenna "under the roof" were placed in an optimal place, ceramic roof, distance from the installation "on the chimney" - about 70 cm. Direct visibility of the BTS antenna - 1.8km 2.8km. The characteristics of the antenna - difficult to determine, but rather not very directional - I turned to different sides and changes difficult to determine - looked quite random The tank is the most coarse - the strongest signal is probably when we direct the antenna with the "side suction cup" at the BTS. Measurements taken to a node in my supplier's network. So far, I have not been able to determine whether they work at 800 or 1800 MHz because these frequencies are used by my supplier in Ireland - Three. Unfortunately, I did not take the router to the roof - but maybe tomorrow I will try at least a few meters :)
My conclusions: This antenna is lame, slightly inferior to that built into the B593s router. The value of profit is at your fingertips. However, if we can place it outside, we can count on a very slight (say 5dB) improvement of the signal in relation to the signal that the router has inside the house. In my opinion, on the outdoor antenna, both indoors and outdoors, the pings were slightly better (lower) and the RSSI more stable (jumped less) - even indoors. Interestingly, I still have the highest and more stable download speed on the built-in antenna - but on the external one.
Now I plan to buy and compare one of the Cybertech or Sorensen antennas here - it depends who turns out to be more interesting :)
Edit: I also took measurements of the B593s-22 router placed on the roof of the garage (i.e. the built-in antenna) - the garage is lower than the antenna on the chimney, but has direct visibility to the BTS. The signal is practically identical to that from the antenna mounted on the chimney. RSSI -69dBm, RSRP -92dBm, RSRQ -7dB. Ping usually 30 ms, DL 35 Mb / s UL 22 Mb / s. So the transfers are BETTER than on the external antenna. Interestingly, the roof is tin, flat, slightly inclined towards the BTS and if I put the router on a stand about 70-90 cm above it, the signal and transfers drop by a few dB / Mb / s. Three ISP support says that this transmitter is down and I have no coverage To quote Sexmission: "You have a nice brothel, sisters!"
Thanks for a few replies. However, I found that the sly pays twice and chose the products recommended on the forum. I did not risk inventions. Topic is closed. Sorensen at home, and thanks to the neighbor and his friends, he is already at home
We did not measure without the antenna. In a few days we will have installations in similar conditions, we will measure it and upload screenshots. There is a forest and a small hill around, so you will be able to do decent tests.
A little more than a few days have passed and there are no tests.
I have been using it for almost a year and a half, attached to the chimney. It's bad, but it's better to pull the bad one outside the roof than to use the built-in one. Distance 2.8 km, direct visibility of the antennas, no interference - rural area. If the transmitter goes down (which happens sometimes in Ireland where I use it) - it catches the signal from the transmitter ~ 10km, which is not "in its axis" - but shifted by about 45 degrees. Unfortunately, very weak. I would not buy it for long distances, because the characteristics are probably the closest to two eighths. I also traveled with her and the laptop connected to the B593 (the power came from the cigarette lighter socket, I know it was risky) in the car looking for the best transmitter. At the level of the roof above the car it is bad, it does not knock down the signal quality. However, at home, above the roof, it is sufficient for my needs, it is slightly better in terms of transfers than a "bare" router - but the signal is still quite decent. When it comes to the antenna built into the router, in my opinion, the right location of the router gives a lot, a lot - and the difference of even 0.5m is significant, and 2m give a completely different signal.
And the comparison of signals from a few minutes ago (location as described above):
I warmly welcome. My question is regarding the Antenna. I have an Antenna from Signaflex DUAL ANTENNA X-CROSS 3G 4G LTE 2x19dBi MIMO the distance from the BTS is about 1 km, does it make sense to use it? I have a D-Link DWR960 router, is this antenna a good choice?
The parameters are probably very good, only a weak Download from 35-40 MB / s maximum.
Does this antenna sometimes distort my LTE reception quality?
Hello, I have such a problem, some time ago I bought a Signalflex antenna, of course, to improve the GSM signal and after connecting to the socket, instead of improving the range on the phone, it interferes within a radius of x meters. Totally drowns out, no phone coverage
The discussion revolves around the selection of antennas for enhancing LTE signal reception, particularly for the Huawei E5377 model, with a focus on Signaflex antennas. Users share experiences with various antennas, including the Sorensen 17 and Signaflex models, discussing their performance at distances of up to 10 km from LTE transmitters. Some users report satisfactory results with the Signaflex panel antenna (2x20dBi MIMO) and express confidence in its reliability, while others raise concerns about the quality and effectiveness of certain models, particularly regarding their gain and signal interference. The conversation highlights the importance of installation conditions, such as line-of-sight to the transmitter and environmental factors affecting signal strength. Users also mention testing methodologies and share specific signal metrics (RSSI, RSRP, RSRQ) to evaluate antenna performance. Summary generated by the language model.
It took us a while to discover this.
