Help with a 5.8 Link

My link is 9km and has a signal of -78 and it keeps bouncing.

RB500’s with SR5 into 26dbi grids

Any ideas?

Quick update.

I killed Nstreme and the connection became stable BUT

My bridge can send data at 10Mbps but only recieves at about .5Mbps
Test shows the same from the other end, only reversed.

Maybe I need to re-align the bridge end?

-78 seems very low for such a shrot link. Sound like you may not have good freznel zone clearance a one end. If you signal is not steady you may have movement with in the freznel zone, (cars, water, etc)

I found what my problem was.

2 bridges back to back.
1 5.8 Turbo at 5765
Other 5.8 at 5825.

I disabled turbo and pushed it to 5745 and both links are good.

If I wanted to run turbo on both, what kind of freq separation would I need?

This is what the link looked like.

(----------------5825--------------------)(-----5765 Turbo----)

My long link was getting interferance from the back lobe of the bridge and also from the remote end of the turbo shooting thru it.

It is now setup like this:
(----------------5825--------------------)(--------5745--------)
and is working good

As far as improving your -78 signal. Try a pair of th 28db solid dishes. I’ve tried the 26db grids and they seem more like 20db compared to the solid 28db dishes. They might be 26db if they were solid. :wink:
