no link 10 mile 5.3 25dbi grids and r52

RouterOS Wireless Networking

I am upgrading a temporary link and get no connections.

Current link 3 sites middle hop just to get around a hill and is running.

Site A
AP sector

Site B
532 with
sr2 and 24dbi 2.4ghz grid connected to site A (10 miles) as a client. routed
cm9 and 24 dbi 2.4ghz grid connected to site C as client. routed

Site C
AP sector

This is working but because it is running from client sectors, it is neither fast or extremely reliable.

The new 5.3 ghz setup below is not working and I am looking for some troubleshooting tips.

Site A
RB 532 with
R52 and an SR5 (I had it laying around) and 2x 25dbi pac wireless grid 5.3 one each in horizontal and vertical arrangement.

Site B
532 with
r52 and 25dbi pac wireless grid 5.3 pointing to site a vertical ( I will add a second matching grid and bonding later. Set up as AP (set the ap at the remote site because it was easier to aim properly)

Site C, wrap board keeps crashing so link not tested yet.

When the 5gig link is up I will use the extra sr2 for customer access and put in a sector.

I aimed the site B (to site A) grid by lining it up with the 2.4Ghz Grid. The site A, I used a compass and map. I am getting no link and nothing shows up when I do a scan.

What I have done to troubleshoot.
Changed to turbo mode to see if the extra bandwidth makes any difference.
Checked that the R52’s were on antenna a and switched the sr5 from antenna a to b and back.
Leveled the feeder horns.
Turned off nstream.

At site A the 5G equipment is 20’ below the AP’s so if no one has any more tips I may be raising the 30lb standoff, antenna, radio array ( I do not want to do that)

Checked the Pigtail?

Faulty Radios?

Your explanation is a little bit vague, no offense. Please try a simple setup of AP Bridge on one side, and station on the other. Check where you are connecting your UFL on R52. Is your scan picking up anything else?

One more thing would be to temorarily remove lightning arrestors to eliminate them as a source of your problems.

Some are only rated to 3.0GHz.
If this is the case replace with Arrestors which go to 6 GHz.

Did you model with radio mobile to make sure it “should” work?

I tested the rb/radios on a table and did a link calc. The pigtails are from wisp-router 6ghz rated 12" I am trying out radio mobie now.

Are you sure you have LOS and proper alligment?

I am not sure of los, I used topoUSA and I negating trees, I have LOS with only 30’ at the a tower site and 20’ at b. I am at about 70’ at first and 52’ at second site. I am not! sure of alignment, i used a compass at site a and visual on the working and aligned 2.4ghz radio at site b.

obstruction (trees) are ~ 1 mile from b and not tall about 30’-40’

This is my furthest point to point and I think it is probalby alignment but with no connection at all it is hard to allign both sides. Maybe set a sector or omni on one side. and align the other to that, then go back switch the sector back to dish and align that side?

site a has more vertical room (40’ more)
site b is at the top already (mabe 5’)

My options seem to be:
Raise site a up to 30’
align both sides again
Test at visual distance with additional radio to verify things like cable, lightning arrestor, and a-b ufl conectors.

Hey nick. Thanks for the tip. RadioMobile is a pain to get setup and started, but it looks to be very valuable with the right datasets.

ARRGH, my settings planning was on meters

NASA once made same mistake :slight_smile: they paid for that a lot more :sunglasses:
