MikroTikmANT LTE 5o 5dBi LTE antenna with two SMA connectors, MTAO-LTE-5D-SQ (with two SMA connectors)

I live in a terrible area. the ADSL/VDSL service is frankly garbage and the 4G reception has never been great.Been trying multiple providers/routers with out much luck. But I finally realised that the Poynting XPOL antenna I was using is just awful (or mine is completely broken) as I found I was getting better speeds with the little included antennas on my router(s)So figured I would buy a few antennas to test them out as I figured I could do much better than the free in the box antennas.The router I tested with was a Cradlepoint IBR1100 which is CAT6 (although I never managed to get carrier aggregation so only as good as a CAT4 for me)with Three I managed to get 10/10 connection first try with this antenna pointed at the nearest tower just put behind a window. Thats a very fast connection compared to what we have been getting. The included antennas got 2/1 and the Poynting was even worse at sub 1mbps both down/upMy next plan will be to get a 2nd router maybe a Mikrotik SXT or something and try to bond them together for an even faster connection.I will note that this antenna did not perform as well as other antennas did on EE so maybe this is not suited to an EE connection? but for Three it did very well considering the area we are in

I have a few 4g routers and there is almost no change to signal.

I live in a rural area, roughly 3 miles from mast and 6 miles from a shop.I first bought a polarized xpol at £80 thinking it would help. it got my speed from 6mb/s to 10 mbs download and nearly 2mb/s upload. Then I had a recommendation on a forum to try this. WOW best purchase of my life25mbs download 12mbs upload, Inventor if you read this I owe you a pint
