Make sure you account for Tx power at full modulation vs. lowest modulation. Always calculate based on full modulation.

Could be he's talking about the gain being +3dB on the data sheets assuming for the gain due to MIMO. At 12 miles I get a -71. The math shows -61. Most of my NBM5 links are similar. I get much better signal with my old 802.11a + PacWireless grids, usually right on the math. ----- Original Message ----- From: John Woodfield To: [email protected] Sent: Thursday, May 07, 2015 8:39 PM Subject: Re: [AFMUG] Nanobridge M5 I thought you gained 2db because of MIMO?

At least 1db from what the antennas say. What's the signal now?

According to the math I should get a decent shot at 24 miles, but according to that same math the NBM5 should have higher signal in every single link I've done. My question here is what is the longest link you've done with the NBM5 25 and what is the actual gain on these units since they don't seem to actually gain 25 as they're suppose to. I'm not opposed to using a Rocket and larger dish, just trying to see what the actual limits to the device are and what the actual gain is for math. Currently I've got the 24 mile shot with a 29 and 26dBi grids, decent, but still using 2008 MT hardware. I need more speed for growth. </blockquote>
