4x4 MIMO performance connecting to cell tower 14 miles away (images)
Posted: Tue Jul 29, 2025 7:37 pm
I have a 4x4 MIMO from Waveform, I have a cell tower I connect to which is 14 miles from me.
I had the MIMO in my attic inside the house and I would often get 5-12 mb/s down and at times up to 20 mb/s - uploads were usually 0.5 mb or less.
I bought a ~4 ft J-mount and mounted it on the roof outside pointing towards the cell tower. Upload speeds have gone now ~3mb/s, but download speeds are have gotten worse, a lot of times < 1mb/s, never exceeding 5 mb/s.
Can anyone help me understand why this could be? How could getting it higher up in the air so there is less obstructions in its line of view causing decreased performance?
I was initially considering getting a 30 ft ham radio tower to put the 4x4 MIMO on top and asked waveform for their opinion and I am being told mounting it higher in the air can create more inference. How can this be?
