Will this STL link work?

Post by abwdvm » Tue Oct 31, 2017 7:07 pm

Completely out of my league here.. We are moving an existing Nicom 9XX STL link.

This is a plot of the new proposed location. Anyone want to hazard a guess if it will work?

What is in the area which penetrates the 60% zone? This path is less than 10 miles and shouldn't be terribly fussy even with some diffraction loss.

Send me the TX and RX location coordinates, the antenna elevations above sea level and the antenna types and I'll run a path profile with the proper parameters. I'm assuming this is a 950 MHz analog link.

I'm also assuming 950mhz STL signal...

Is the path & fresnel zone shown done at 950? It looks mighty skinny for 950mhz at 13km.

That looks like it is 2.4 or 5 GHz. I ran the path study for him and at 950 it's a lot "fatter" at 60%, but only loses 4.5 dB because of it.
