I'm doing a new installation of a Ubiquiti PBE400 that will require a cable run of almost 525 feet.
Now, I know I'll need a POE Extender for this but my question is if the 12 watt POE injector that comes with the Powerbeam is adequate to the task or do I need something different? I suspect the 12 watt one isn't.
My plans are to use Ubiquiti Carrier Class Tough Cable for the run but I'm open to less expensive alternatives (but only if it doesn't compromise reliability and ruggedness).

As far as power goes, they pull no more than about 4 watts. Your biggest concern there would be voltage drop. But the nodes will run down to about 11 volts and I don't think you'll have 13 volts of drop across the line.
If you do get it running, run pings with large packet sizes and see if you're dropping any packets across that really long stretch of cable.
Report back - we'd be interested in your results.

If it's a true POE extender (that is, a two port network switch that regenerates the timing) yes.

Exactly my plan. See https://www.poetexas.com/
Anything and everything running CAT runs over 100 meters
Howdy:
I am somewhat sure that you will need a POE pass-through switch.
I had some random lengths of CAT5 cable laying about.
With a Ubiquiti POE-24-12W I was able to power-up and link my PBE-M5-400
with up to 474 feet of cable, but not with 524 feet of cable.
If you don't need/want any LAN connections,
perhaps a 24 watt POE and a Ubiquiti Nano Switch (N-SW) in between would suffice.
I hope this helps,

I ordered one. Heck for under $20 delivered, worth a try!
Looks good to me.
I did not think about an indoor rated device.
I have only been using outdoor rated switches lately.
Good luck and let us know how things turn out,
Chuck
In a waterproof enclosure of course...
I'm hoping to install next week and will report back
The weather hasn't been too cooperative so I haven't been able to do the installation, however I did fabricate the cables here at my shop and ran some throughput tests using the full 525 ft run (with the Extender inserted at 328 ft of course) versus a short 6' run between my hAP-LITE tunnel and a PBE400. The cable I'm using is Ubiquiti Carrier Class shielded outdoor CAT5e
Using iPerfSpeed, there was no substantial difference in speed or retries between the 2 cable lengths so it seems things will work for me just fine. (I can post the iPerfSpeed results if anyone is interested)
Better late than never I suppose.
The Pacific Northwest weather FINALLY cooperated and the installation is complete. I'm connecting to a node 25 miles away with excellent results. So anyone who needs a very long run of CAT cable for their Ubiquiti device, this is how to do it!
