The other thing that plagued us, at least with the 600SS, was the protection diodes would get partially blown after a surge event, causing really bad CRC errors. We wouldn’t have a clue until the customer called bitching his Internet was slow. Usually, not always, we could force 10BaseT on the SM until we could roll a truck and replace the 600SS. Actually we would take out the PCB and replace it with an inline coupler. Now that Chuck has a gas tube replacement PCB maybe we would use those instead of a coupler. I don’t think a GDT would degrade like the diodes. FWIW we still have that problem with the Tycon POEs that include a surge protector, but we can just send UPS out with a replacement and have the customer DIY the replacement.

I doubt any of the usual suspects are listed. The alternative would be to use shielded cable and ground the shield with a grounding block at the entrance to the house. That seems to be the approach taken by sat TV installers, but they are using coax anyway and it has a shield. With a grounding block, I’m not sure if the requirement is that it be bonded to the electrical system ground, probably with a humongous wire. That’s why we stopped putting the Canopy surge suppressors on the outside of houses, in our rural area, properly bonding the ground is impossible on many houses. But with imperfect grounding, we found that the outside surge suppressors greatly increased the likelihood that the customer’s router would get the Internet port fried. Ground potential differences. The old adage “ground’s ground the world around” ain’t true, at least not when lightning hits a tree in the yard or the transformer on the utility pole.

Who does it? We do and always have. When lightning burns down the house I very much want the fire inspector to find the melted Cambium logo on the surge suppressor cover. We built it per NEC, sorry about the house burning down. Sue the guys with the deep pockets, not me.

We have been doing it since day one by placing inside at the antenna cable ingress location. Makes for a great coupler to change the cable from outdoor to indoor as well. Since Cambiums SS's have gotten stupidly pricey, we have switched to Ubiquiti, but they suck to mount cleanly and quickly. And to be honest, Mccowntech are expensive as well. My question is this, who thinks it's worth it to do every home all the time? -- -- Sam Lambie Taosnet Wireless Tech. 575-758-7598 Office <http://www.newmex.com/> www.Taosnet.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
