|  New WISP setup complete 6 stories up
I have recently completed my latest setup 6 stories up in downtown Newark, Ohio. I thought I would share some of my photos for you to see. Some of the equipment I used at this location are: Motorola 5.8Ghz 58600 PTP Bridge and 4 5.8Ghz Proxim 5054-R BSUs. We are a small independent ISP trying to bridge the gap between DSL and Cable internet services here in the area. IF you have any questions feel free to ask, IM me, or e-mail me at ccalhoun@alink.com. I am always looking for input on my work as I am new to the game and still learning.
Thanks for looking!

| Very nice. We just shook hands on a new POP location today. We are waiting on the lease so we can start working on the site. I am going to take some pictures of our next site and post them as well. Some of the guys in the Photos of Broadband gear might like this post as well. |

Wow...really neat pictures. Nice looking setup.
Who is the mfg of the non penatritating roof mounts? They look real nice.
I like your grounding.
Where are you running your green ground wire to? Probably have a building ground nearby?
The one square white AP has a ground wire coming from the connection to the antenna connector. Are you by any chance using a Polyphaser surge protector there?
Good luck with your WISP side of your business. |

The masts I am using are from »www.lashen.com/. I have modified them with a taller 10' rigid conduit pipe to make them taller. They seem to have the nicest, reasonably priced masts around.
The ground wire ties into a building ground on the lower roof.
That is correct on the ground running to the in-line surge protector radio. That is a Polyphaser at work there.
I have plenty of more work to share. I am also working on a city wide 4.9Ghz Mesh for public safety using Proxim AP4900 aswell as a few other POPs and a 2.4/5.8Ghz mesh running Proxim AP4000s.
I am still working out a few kinks on this POP with a slowdown on the PTP link because I cannot get the head end Dish high enough to clear a line of trees. These radios seem to thrive on multipath distortion but this tree line is still hampering the connection. These PTP radios use vertical and horizontal polarization for sending and receiving and should work in NLOS conditions. |

Maybe you can negotiate with the building owner to share the cost in exchange for protecting the building. |

i am surprised that you did not use mats underneath the non-pen, and only have a block of wood there

Obviously a difference of opinion, but I cannot share yours. Public is right. The skinny stranded wires can only bleed static buildup, not lightning. Also, the masts should poke at least a foot higher than the sectors, not lower.

Most of the roofs we get on have HVAC units that have 4x4 blocks under them. Many buildings have 4x4s with conduit and gas lines attached to them as well. |

Great job on the install. It's nice to see clean installs here.
Grounding nazis.... phffff 
I really like what I see, but here are some thoughts since you are open to them.
There are a few too many bends (in my personal opinion mind you) as you come off the arrestors/ODU's and down the mast though. Remember that lightning wants to take the path of least resistance and go in as straight of a line as possible.
I'd have the runs off the arrestor/ODU not sweep up and then down. Instead they should just sweep gently down. There are some details like bend radius and all that bullcrap but I'm not going to get into that here.
I'm off my soapbox now. I commend you on your grounding though. No one around our area spare myself, even puts that much effort into grounding rooftop or even tower gear. I've done similar jobs as cleanup of other contractors (50 rooftop sites with a total of 4 radios sometimes per site!) and appreciate the time and effort it takes do do this.
You get my seal of approval.

Nice and neat install. However, agreed on the mats. We get them from Skywalker and they aren't that expensive.
Good luck on your WISP!

The little wires are used to prevent damage from sparks due to static buildup and limit secondary effects of a lightning strike, These are totally inadequate to prevent damage from a direct strike.
Look at the German picture. An Air terminal protecting the vent ...........
You decide if it cheaper to replace everything each time there is a strike. |

If that is rubber tape weather proofing on the antenna connectors then you need to put a couple of layers of black tape over it or it will dry and crack in 6 months.
Edit - Next time you buy a UPS get an APC, not a smelly Belkin. |

The stuff running across the walls in that picture are supposed to prevent birds off the building and sh&*ing down the side of the building. |

You get my seal of approval. Thanks for your input. I will try to straighten out the grounding cables a bit more, maybe I can move the grounding block to the lower part of the mast and just run them all down straight into the block. The building itself has no grounding on it what so ever.
The weather wrapping is PVC tape then weather tape (sticky rubber stuff) then PVC tape. This way if they ever have to be torn down we can get them apart.
The treated 2 X 8s will not harm the roof and that is what the roof company said to use. They said they will not rot or harm the roof in anyway so I think I will stick with them on the next install as they are less expensive then rubber mats. The rubber mats are $65 a piece as you can see the ones I put on the larger mat.

Edit - Next time you buy a UPS get an APC, not a smelly Belkin. I am not so sure if your eyes are open. But there is plenty of PVC tape around the weather tape on the connectors. Also we have always had better luck with Liebert and Belkin UPSs. They have never let us down like the APC ones have.

Also, the masts should poke at least a foot higher than the sectors, not lower. What size grounding should I be running to the masts from the building ground. The largest ground wire I have seen is 6 guage and that is what I am running to everything.
Also the mast should poke higher so they are hit before the sectors. Is that correct?
