Hi,

I am setting up a 4.40 km wireless link with SXT Lite 5 AC on both sides. From observation & site survey there are no trees in between and some low-height buildings are present in between. Rest all are open field.
Height at AP - 60 ft (Can be increased 10 ft more)
Height at Client End - 55 ft. (Can't be increased without new construction)

I tried a lot of alignment and height alteration. But no way I am getting more than -74 signal. When connected the tx/rx is 74/74 to 76/76. Almost same tx rx signal strength.

Does the problem lies with alignment or have height issue? Please guide.
