I'm FINALLY in line to get Fiber with either 100/100 or 1000/1000 up/down speeds at my house in Mississippi.
One of my plans is to run wireless from my house to my workshops, which are about 100 yards away. For that I bought a pair of Ubiquiti U6 LR's to send and receive from the house to the workshops.
Since these will be outside (under eaves) what are the TBN recommendations for Ethernet Surge protectors?

Can't necessarily speak for that model but I've used Ubiquity 5gHz links between communication towers and they seem quite robust. I think I've only lost one, and that was on a tower that took a direct lightning hit. The PoE injector was on a UPS, and we used shielded outdoor-rated CAT5 but that was the only protection in place.

just use the ones you linked its what I use. Really wish you would stop using the wrong model AP's, those are not Point to Point radio's. Not so sure why your so stuck on them.

Because I want to have wide area coverage on my acres, not just point to point.

I have those on my external antennas and dishes along with a 6ga ground wire back to a good ground. The downside to them is that they are only diodes. They are a bit of a grounding challenge as the screw that holds the case on, also holds the PCB to the case and the ground wire to the PCB. I replaced the supplied wood screw with a stainless threaded bolt and enlarged the ground hole out of the case to fit 6ga copper ground wire.

For cheap insurance, I added gas tube surge protectors inside the building at the other end of the cable.

I would recommend shielded Ethernet cables throughout, and if the Ethernet cable are exposed to sunlight, UV protected exterior rated shielded cable will last longer, but is a total pain to find, and may not be worth the hassle for most folks.

Worth it? Who knows? Since there isn't a big cable run, there isn't much of an antenna effect to get a big difference in voltage, so the risk to electronics isn't large. Then again, if there is a surge, these will all keep any surge to a bare minimum. For a long run, I would put both types of protectors at both ends.

I am not fond of the fire drill that results after an unexpected failure; you suddenly need the electronics, cables and systems back up instantly, and I am the one running around trying to get things working, order new parts (overnighted), then repair them and get things sorted out right. Personally, I certainly do prefer the belt and suspenders approach to running around.

All the best,

Peter

Are they “one shot” (I.e. one and done) protectors? That is, if they do their job, do you have to replace them, and how do you know?

Being wireless, I’d want my surge protection in the power supply rather than the Ethernet.

all surge suppressor are a wear item, they use mov's which take hits until they don't, some of the better units have lights indicating protection. the ubnt units do not.

As@LittleBill21 points out surge suppressors are a wear item. If any of your surge suppressors wear out, I would replace the whole lot. I wouldn't rely on lights; I have had a few that continued to glow, even after components had smoked.

All the best,

Transients can and will go anywhere not just the mains. We had a lightning ground strike near by - not a direct hit. My buried CAT5 cable between the house and barn picked up induced current and fried EVERY device on the network and they were all connected to UPS's.

Buy yourself some Ubiquity gigabit ethernet surge suppressors to help isolate your network wherever your cables exit the building. On a direct strike all bets are off.

Ubiquity gigabit ethernet surge suppressors
Very interesting - I looked up the instructions for the device.
  • Using an M5 machine screw and nut (not included) to attach a drain wire that is connected to a remote grounding block or structure.
I had not run across the term "drain wire" before.
BUT I have had to drain "wires"!
I had a cable TV run of RG59 installed by the cable company. It ran from across the street, over a pole, thence to the corner of my basement, about 100' total.
We started having problems with TV reception, cable guys came out said everything looked good, blamed it on my interior runs. It got worse after rains.
I disconnected their exterior run from the outside and it started emitting a stream of water like a 3yr old urinating.
Apparently whoever strung the line from the pole didn't put in loops at the pole and the line filled with water. So until I could get the cable company to replace the cable I'd just go out and drain the cable wire occasionally.
