WS-6 Mini POE out length

First time using the WS-6 mini and I am trying to power a Ubiquiti AC Rocket Lite radio at 300ft away. I know this is probably pushing the limits cable length wise but has anyone succeeded at getting something successfully powered at this length? I am using an Air Fiber power injector 50V @ 1.2A and am able to successfully power the device but as soon as I logon to the radio it reboots. The watts on Port 3 POE out varies between 3.9 and 8 which is not enough as I need around 11 to keep this powered. Any insight would be appreciated as I am about to shorten the cable run.

Thanks Paul

This has been done many times even by me.

Your sending 50+ volts to WS-6 and it steps down to 24V. If your WS-6 Mini is not rebooting you can probably rule out the WS-6 as the cause?

Possible problems:

1) Your not getting good contact on all 4 pairs but if you have a 1G connection to WS-6 MINI then that is not the issue as 1G requires all 8 wires.

2) Your POE Brick is bad.

3) Your Radio is bad, swap out and see.

4) Your MINI is defective, swap out and see.

WARNING: Your Rocket AC lite has access to tower Earth Ground and at this distance IO know your not binding tower ground to electrical service ground so you are bonding the 2 ground potentials through your Ethernet cable which means you will suffer damaged switch and or radio.

Unless your using the WS-6-MINI to go vertical then it is possible your tower ground rods are indeed BONDED to your electrical service ground rods.

If the is to reach out horizontal/vertical and not a tower then I would NOT ground the mount the radio is located on and as always if this is an older electrical service add 2 NEW ground rods and BOND to existing ground rods.


99% of all WISP equipment damage is from ground current (I own a WISP)
Another common cause for damage is a shorted cable or incorrect POE option applied to device.

Here are some good posts on grounding:

Read the posts above but the basics are as follow:
Tower ground rods must be bonded to electrical service ground rods HEAVY #2 wire.
I always add 1 or 2 “new” ground rods to older existing electrical services.

Thanks, I've swapped out the radio and POE and even though the cable tests out good I'll try putting some new connectors on each side and see if that solves the issue.
