View Full Version : Pico 2 HP Range out of the box

Hi Guys does anyone know the actual clear LOS range of the pico 2HP, are there any tested stats from ubnt on these?
Also do they have dual ethernet ports for lan bridging like the meraki outdoors? I was thinking of 2Ghz mesh with 5Ghz Backbone.
I heard some chatter about Pico HP 2 shipping with open-mesh (robin) will this be from all distibutors? Very Anxious.
Thanks :wink:
There are too many variables, but here are some predictions.
100 miles with Pico 2 HP shooting to a PS 2 at lowest data speed and zero fade margin.
About half a mile with Pico 2 HP shooting to a Loco 2 at highest data speed and 10 dB fade margin.

what about Pico 2 HP 2 Pico a HP 1000ft 2000ft
I get 1500ft with meraki outdoor to meraki outdoor with 10dbi rubber omni aerial, and that a 200mw radio.
So just wondering how a 800Mw would match up.....and we are shooting at just above roof top level most times.
Given the same setup, you won't see any difference as the Mik will certainly see the 800 mW Pico at a greater disctance, but the Pico won't see the 200 mW MiK.
Is that what you're asking?

I think laser3 is asking the pico2hp mesh/wds-ap distance capability.
Like split up few pico2hp to outdoor area and thinking them to connect each with maximum distance like mesh.
If meraki goes 1500ft, pico2hp to pico2hp could go up to 2000ft or up.
Suggestions?

yeah thats correct bgoksel what would be the rage distance between 2 pico2HP with clear LOS and not interference
If meraki goes 1500ft, pico2hp to pico2hp could go up to 2000ft or up.
Meraki:
23 dBm TPO + 10 dBi antenna = 33 dBm
Pico HP
29 dBm + 6 dBi antenna = 35 dBm
The Pico has a 2 dB improvement.
1,500 ft = 93 dB loss
2,000 = 95 dB loss
Therefore a Pico will preform as good at 2,000 feet as the Meraki does at 1,500 feet.
Did you *really* want to know all that???

Yes that near enough answers it, Thanks I guess the only question now is where do I get a 10-12 dbi rubber omni antenna similar to the one the pico comes with. All the one I find online are the ones that can tilt & they seem to let water in right where it has the elbow joint.

Hot glue - used for home craft or a tube of silicon in a handymans gun works well.
Since I don't have any need for those little "back of the set" tilt rubber duckie antennas, I have not closely read the specs on them...but 6 dBi gain sounds familiar.
A length of heat shrink tubing with that wide temp optimized hot melt sealer inside.
Consumer grade hot glue or silicone glue will ultimately fail...that is a given.
As a Sunday afternoon project, I compared the temperature range performance of some consumer grade hot glue and found at below 40º F it was harder or more brittle than the commercial grade glue inside the heat shrink products. It was more prone to separate from the base material. The commercial grade hot glue had more consistent adhesive properties across a wider temperature range.
Silicone glue is a very durable adhesive when used for a specific application. In other words, you should use it when the applications warrant it, not as a general use adhesive. It cannot be used when gluing plastic together as the volatile components in plastic eventually flash off and act as a mold release, and the silicone glue simple peels right off. An exception might be for a new product that is specifically formulated for Plexiglass and Lexan materials (I have a tube of it, but haven't personally haven't tested it yet).

I suggested the silicon not for adhesive purposes but for the waterproofing capability. I have had a series of solar panels up on the roof that were not rated for outdoor use because water could get under the plastic frame - so I used silicon around the edge of the glass and a year later the water still hasnt gotten in. They are only 5watt panels though so no big loss if it didnt work. I thought this could be used to waterproof the joints of the antenna here.
