RE: Fw: [WISPA] Grounding questions/help
I replaced just the SBC (kn-205 board) and all is well for now, the radio themselves are okay. So I'm not sure that the current came in through the antenna, but rather some how came across the cat5, connecting the tower ground to the AC ground (if indeed they are separate grounds) I will find out tomorrow and hopefully resolve the issue before I loose any more equipment Dan > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Marlon K. > Schafer (509) 982-2181 > Sent: Tuesday, August 02, 2005 8:14 PM > To: Jeff Liebermann > Cc: wireless@wispa.org > Subject: Re: Fw: [WISPA] Grounding questions/help > > > - Original Message - > From: "Jeff Liebermann" <[EMAIL PROTECTED]> > To: "Marlon K.

Sometimes, only sensitive parts of the circuitry gets zapped. My guess is something died in the radio which is causing the reboots. It might also be something simple like the terminating end of the POE circuit, but my guess is that radio is the problem since it seems to sorta work until it reboots. Is it also possible that not having the tower grounded to the AC is making this worse? -- # Jeff Liebermann Liebermann Design 150 Felker St #D Santa Cruz CA 95060 # 831-336-2558 (voice) callto://JeffLiebermann (skype) # http://www.LearnByDestroying.comAE6KS # [EMAIL PROTECTED][EMAIL PROTECTED] -- WISPA Wireless List: wireless@wispa.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/

Use these on ethernet. They ground all 8 pins, clamps voltage at 60v, and provides bidirectional protection.. Never had one fail in 7 months. I live in the state of Michigan. 2nd worse for lightning.

RE: [WISPA] Grounding questions/help
Short - Straight - and on a single point ground system. You want to become one with the tower. You do not want to make your equipment the least resistant pathway to ground. You might also request that additional (three (3) or more) 8 ft ground rods be driven on 16 ft centers from existing rods and bond them together with #2 solid wire to each other and the existing rods. We have used Tripp-Lite TLP810NETs in the past. It provides surge suppression for Ethernet and power. Tripp-Lite DNET1's also are good for Ethernet surge suppression. I would also recommend if you are using shielded CAT5 to properly ground it at the tower and before entry into the enclosure (similar to a coax grounding kit). Keep the lightning on the outside.
