I’m trying to get a rough estimate of how picky these 5GHz grids are. I have a few, don’t remember which one matches which specification, but 6* beamwidth by 4* beamwidth.
How can I figure up the rough size of the signal at 6.6 miles? Rough estimate is a half mile, which is still a tiny target at that distance. I’m trying to get the one on my tower close before I have another guy line up the other side of my p2p shot.
Bottom line, I think I’ll have to be at both locations at the same time, which is going to be kind of difficult. If I can get my side close enough to dial in one side, I can get back here and get mine finished at a later time.
I guess a simple question, what are the odds of aiming one antenna at a tower and getting it close enough to work with without reading signal levels at 6.6 miles with a 29dBi 5GHz grid?
You have a triangle with 2 knowns sides of ~6.6 miles and an angle of 4 or 6 degrees. Solve for the side opposite of the known angle.
OK…I don’t know the formula anymore but google does.
Ends up being about 1/2 mile. You should be able to eye it up better than that though.
The old fashioned way is like so:
Know your elevations at both locations and the height that it will be mounted.
You should have line of site…if not good luck with it working reliably.
Mount ant-A and point it at the target as best you can. Check your tilt.
Mount ant-B and align it visually and by monitoring signal strength.
Sometimes you have to go back to ant-A and re-align it by monitoring signal strenght.
You should have a pre-calculated signal strenght that you expect.
Thanks for confirming my bad math. My wife figured it up, came up with about the same answer I did, but I wanted some info from someone with experience.
I did google for hours, never came up with anything. Found hundreds of links to figure the parts I knew, but not the info I needed.
