Stable Longest Link for a 5700BH20

I am trying to work a 5700BH20 on a 22mile link but seems very low RSSI, although I believe it is surrounded by 4 pops w/ 4 5750APs each within its .3-.5mile circumference. 2 of the POP are my competitors.

I have not tried relocating to escape the frequencies surrounding it.

Now my question are:

1. How far is your longest but stable link using 5700BH20 20mb?

2. How many MB can you attain using linktest?

My 2400BH20, 75% utilization gives 9.30mb to 9.7mb.

Please share me your experiences.

My 6.6mile link using 5700BH20 is giving this reading about 12.9mb:

We have several links at 20+ miles. Our longest is 26 miles, 5.7 13Mbit throughput total, 73db at present. been in place since 2003. (Had P8s, recently upgrade to P10s)

Is that a connectorized BH or one with the 27RD reflector?

Did have the standard Reflectors for a while which had the signal hover around -73.

Moved to this dish: … r-grid.php

Which got the signal down to -66. Been there for about 2 years now.

"Moved to this dish: … r-grid.php"

I used that same dish to build a covered version for the highest site of ours with the most extreme weather conditions. The distance of the link is 24 miles. I really did not like the grid for our traditional links. I dont think you can beat a 5.7 BH setup in a 27RD or KPP reflector (but have not tried the warm32). The grid was cheap and poorly built. However, it was the only reflector or grid of the three versions we had laying around that would fit the application for a covered grid. It has worked out well with the 2.4 setup.

Here are some recent pics if interested:

Wall of ice over both dishes:

5.7 BH that is now stand by for back up because 2.4 worked better.

I cant believe this has held up for two years. This ice weighed over 50# and bent the bolt holding arm onto the dish and the dish did not break.

Ice is cleared away and now you can see my home made covered dish:

Impressive hoar frost.
