The boys down in the Southern Yellow Pine parts of the world say that pine is worse than other types of trees.

I don't think there really is such a thing as typical loss through trees... there are way too many variables to be able reliably calculate anything, in my experience. But it's a pretty good bet that 5ghz will be worse.... although if it's a PTP link, you do have the benefit of being able to use a lot more TX power with 5ghz, so you might be able to make up for the additional loss.

Seriously, I don't know, but I'd be willing to bet that is not going to work well at all.

So I guess if that's true in your case then you've got 100m or so of trees to get through. I do not know the equivalent number for 5.8ghz. Maybe somebody else can fill in the blank. ------ Original Message ------ From: "Christopher Gray" <[email protected]> To: [email protected] Sent: 4/17/2017 4:51:23 PM Subject: [AFMUG] Equivalent Loss When Moving NLOS from 3 to 5 GHz? I'm looking doing some calculations for a link that is currently 4.7 miles effectively with M365 NanoBridges. The signal calculates out to -59 dBm, but in reality it is -71 dBm (12 db loss through foliage). Is there a decent way to estimate what the equivalent foliage loss would be at 5 GHz?
