Review: Very Strange - I first checked this at the sames level and I achieved about 25% increase in mbps. (30mbps). Then went to all the trouble fitting at ceiling height close to a window. I was shocked the signal dropped to 4/5mbs far less that without. So I moved it back to original low level position just a metre from router on a coffee table, now I am getting 40 to 50 mbps. No idea why this happened but I am very pleased with the end result. So if your router has just one external antenna this piece of kit is for you. My Model broadband signal was good, now it's great. Cancelled landline package and use router as phone with Three unlimited data,minutes, text, £11 for first 6 months then £22. Edit: Did speed test this morning (13/10) It was 59mbps. Contrary to other reviews I get better speeds when antenna setting Router is set to auto, not external or internal.
Review: Doesn't seem to make much difference. In fact at times the signal is weaker with the anthena. - Using with Huawei wifi router and the signal strength seems sometimes slightly better but other times worse. The cable is only long enough to use in a car/van, way too short to mount on a pole.

## Questions & Answers

**Q: Will this boost my mobile phone signal?**
A: No, sorry, it wont work with a phone as there is nowhere to connect this to on a phone. It only works with 4G routers that have an external antenna socket.

**Q: will this work in a router with a ts9 antenna port?**
A: No as it has the wrong connector, adaptors are available as an add-on.

**Q: Does it cone with any cable?**
A: Yes, it comes with a fixed 2m cable with an SMA Plug connector on the end.

**Q: i would like to ask if this antenna would work outdoors with a cell phone signal booster?**
A: Well remember that such devices (boosters) are illegal in the UK... well there is an Ofcom standard but I'm not aware of any that conform. Saying that, if you COULD find a legal booster then, yes this antenna would work.

### ⭐⭐⭐⭐ Works well and feels well made
*by J***K on 15 January 2021*

It is hard to really know if they have improved our 4g speed and stability or if the internet provider has improved things at their end. However having played with the position of the antenna and using an app to get the direction of the tower we are now getting a reasonable signal and better stability. We did purchase 2 antenna and currently only using indoors, so we may try outside in the better weather.
