Very decent for its price from a reputable company in the field. The 5db is the minimum and really helps in difficult coverage areas. Don't believe the specs of other antennas that supposedly have a gain of 25-30db+. These are completely 'inflated' values that do not correspond to reality. Important: Combine it with the shortest possible high-quality RF240 pigtail cable to have the lowest possible signal losses, such as the Maxlink Cable SMA male - SMA male. They are more expensive than the antenna but the result is worth it. Also, although it is omnidirectional, it is good to point it towards the tower with the best signal for your mobile, it makes a difference.

So guys, the antenna is awesome, I was getting 100 Mbps inside the house with a TP-Link MR600 v3 router. I put it up on the roof with 10 meter cables, and I got 190 Mbps and 100% signal. The cables are these (MaxLink 08-SM-SM-10, Pigtail RF240 10m - SMA male / SMA male)

I installed it on a mast with two 5-meter very high-quality cables (type RF240 which are more expensive than the antenna!!) and the signal strength increased by 25 to 30%.

I got it and I'm giving it away along with the mikrokit chateau lte6 ax today 2.1.25, I opened them, tried them, but they didn't do what I wanted

Average to poor signal reception. With the internal antennas of the hybrid router, I get about the same signal while I placed it outside with cables.

In an area with weak signal, the 4G router makes no difference with or without the antenna. If you already have a good signal, you might see a slight improvement, but what does that matter then? Here we are looking to have....

The antena is perfect, it does its job flawlessly without any issues or disconnections, and it also plays a significant role depending on where you place it!

I have it with Tp-Link MR600v3. The router is on the ground floor and with the factory antennas it reaches 20-25 with this antenna on a column 3-4 meters above where the router was, it reaches the same. No difference. Maybe I need something else? :/

Very good for me. What do I mean. Camera outside the house 15 meters away and the signal is stable. Range up to 30 meters.

It was installed on a mast with a 5-meter cable. The height of the mast from the ground to the 1st floor, surrounded by buildings all around, without direct visual contact with the antenna. It greatly improved the speeds and signal of the mr600 v3. The average speed is 100 down with 40 up. The only negative is that the connectors for the cables have a very small distance between them and it is not convenient to tighten them by hand, an 8mm wrench with caution helps.

Much better than the factory ones in 4G router TP-link.
It's worth the money and more.
I'm thinking of ordering another one for a second 4G router

In terms of transfer and replacement, I have no complaints, but the product does not do its job. I use it on a TP-Link MR600 router with a Cosmote card. The signal is constantly at 50% speed, no matter which band I use. In the mornings from 7 am to 2 pm, the speed is below 1 mbps, and in the evening it reaches 3 to 6 mbps. Cosmote blames TP-Link and TP-Link blames Cosmote, and you can't get anywhere. We are very disappointed, as we expected better performance.

The other issue is that it took us a long time to find the cable in Thessaloniki, at least.

Compared to the regular antennas of the TP link MR600 4G+ router, I gained approximately 10% in speed in a densely populated area within the center of Athens.

It is worth it and if they are good and relatively small cables and you have it outside, inside it made minimal difference

I combined this antenna with the MikroTik Chateau LTE12 and a 5m high-quality cable. I installed it in a tube about 2.5m long on the balcony of the second floor, surrounded by taller buildings and without direct line of sight to the antenna I am connecting to. This antenna is the best value for money. It provides a significant improvement in signal strength. Be careful with the cable. Get the shortest length possible because there are significant losses. Initially, I had the exact same cable but in 10m length. Check the two screenshots that show the differences in signal. The antenna was placed in the exact same spot. The only difference was the cables. The speeds I am currently getting, locking onto 2 bands, are 100+mbps download and 50+mbps upload.

The best purchase for an antenna, especially for this price. I had two 7dbi antennas (around 70€ each) and they didn't have such a good and stable signal like this one! It is used with tp-link mr600 and works perfectly on 4g+ with speeds over 130mbps download/40mbps upload with a Cosmote sim.

I put it on my Cosmote ZTE with the 4G package that it offers, where I put the ZTE in a waterproof external box, and where it was playing at -95db, it brought me down to -84db, which I believe is satisfactory as I have buildings in front of me and the Cosmote 4G antenna is about a mile away
