I've got a 2.1km P2P link using two SXT Lite2 units (NV2). As you can see from the attached screenshot, the TX/RX for channel 1 is a little crappier than channel 0 for the client.
Would this be due to alignment of either the AP or CPE, an 8 year old SXT that is faulty, or a combo?
Also, what polarisation is channel 0 and 1 on SXT units? Is channel 0 horizontal or vertical?
