Re: [WISPA] Lightning protection used on installs
The newest version of Citel's outdoor protector is pretty awesome also. Its a pretty close competition on whether the Canopy or Citel is better. The Citel can be had at about the same cost, depedning on how buying.

Re: [WISPA] Lightning protection
A combination of surge protection and proper grounding is the key. We utilize a multi-point ground tester and find a large portion of our sites have poor grounds (less then 5 Ohms to earth) or some crack head stole the buss bars and copper. (Very likely in FLA). Testing has become part of our semi-annual maintenance. We also utilize static dissipaters to reduce the conditions for lightning to form around the site as well as surge protectors. As far as Transtectors, The large one for the canopy is very well designed and works well. We have replaced all of the ALPU-ORT (PTP Transtector versions) with the new Motorola units. They stand up better, are made for hanging on towers and don't fill with water after baking in the sun for a few years.

Re: [WISPA] Lightning Protection
Jim, I too have the pleasure of enjoying the wonderful Kansas Storms... Our main tower had been hit three times (in a row, in one season) while i have been using it for wireless, and I got fed up with changing out the equipment each time. I have found that on most of the towers, if it has a good ground, and you leave some of the tower, or a pole up higher than your equipment, there are no Lightning problems. On our main tower however, it was not grounded well. So in doing a little research I came across this kit from glen martin (I am sure there are others out there too) http://www.glenmartin.com/catalog/lightning.htm It came with everything but the wire to run down the side of the tower, which i was able to purchase from our local electric dept. I installed it, as well as drove a rod at each leg (it was a self supporting tower with three legs) and grounded each as well. since this was installed, I have not had a single problem through two seasons of storms now. I also installed a surge protection system , in my equipment room, that is connected to a ground bar that is tied to the tower as well. (an electrician told me to make sure your have your grounds tied together. Something about ground differentials, or equipment from two different grounding sources. I cannot remember the exact reason) In the past it seemed I was losing the equipment (or more specifically the mini-pci cards) from at least one tower everytime it decided to cloud over, due to another problem as well. Come to find out most of that problem was related to static build up on the antennas. (in fact every Omni directional antenna i had nearly, popped a card each time it clouded over) I found a solution to that as well, which you can read about here ( http://forum.mikrotik.com/viewtopic.php?f=7t=9734hilit= Topic:Wireless card recieve blows issue, in Wireless Networking Category ) on the Mikrotik Forums.

RE: [WISPA] Lightning Protection
So does this mean that cabling and equipment should be grounded to same source? I understand grounding the cable prior to entry. Does grounding my cable to one ground and then using the shelter power, which is on a different ground, set up a potential on the equipment? Maybe disconnect the ground on the power side and bond everything to a single point? Chris Your sapose to do both ground outside before you get to the shelter portand insideto tie into the ground ring inside the shelter. -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
Re: [WISPA] Lightning Protection
Your sapose to do both ground outside before you get to the shelter portand insideto tie into the ground ring inside the shelter. Your grounding should be every 75 to 100 feet of your cable run down the tower.So if you have 300 feet of cable run your going to have 3 grounds in your system TOP, MIDDLE, BOTTOM. I usually see at least two TOP and BOTTOM, one at the ODU and one inside or sometimes outside if the grounding bar/ring is on the outside of the tower.Nothing really wrong with just two, butone every 75-100 feetis standard. It can be different from tower to tower depending onhow the site was engineered and built. Example most ALtel sites have a ground bar at the port entery ( outside) to the shelter which ties into the main ground ring, on this site yes you would ground outside. You still have to ground the equipment to the rack inside the shelter, but your surge supressor would go outside. Other sites you will have to ground inside because the site designhas the bus bar ( ground bar ) inside just after the entery port. Both designs are very common. So to answer yes it does good to have a supressor inside its you last defence untill you get to the radio ( idu ) and then as long as its grounded to the rack and the rack is grounded to the ground ring inside the shelter it should be a well protected link but even then it isnt a garrenty that you are 100% safe. Lightning is a strange hazzarded to try to ward off. I am in Florida so I see just about everything as far as protect ion goes. And I can tell you right now that if your customer isnt a MAJOR carrier you site is probably not properly designed aganst lightning strikes so you need to bring them up to speed and properly ground the site or the customer is just asking for trouble.I work with a local WISP that had no Idea about grounding and I have had to redesign the ground rings on most of their sites. SO FYI it doesnt matter how much protection you put in if it isnt properlydesign inside and shelter and outyour equipment will get fried everytime.

Re: [WISPA] Lightning Protection
The only reason I asked this and think it's funny - *no offense intended* is b/c one of my techs did an install like this - Apparently when the tower got struck by lightning - the enclosure exploded due to the discharge ring on the supressor inside of the box... I mean literally exploded. I had routerboard / enclosure crap for 100s of ft all around the tower. Wish I could have gotten that on video.
