A good reason to mount your antennas on standoffs is so guys like me don't have to climb around them. :-) -B- Sent from my Verizon Wireless BlackBerry -Original Message- From: "Tom DeReggi" Date: Sun, 2 Aug 2009 23:34:13 To: ; WISPA General List Subject: Re: [WISPA] Tower standoff or not question My understanding was that an electrical field of about 10" wide from the tower leg, was likely to flow down it, if ever hit.

Re: [WISPA] Tower standoff or not question
Perhaps a larger problem is having the copper cable run down the leg. I had a tower with a 10' standoff and the ethernet ports were routinely fried - with lightning protection. I put a switch on to take the hits until getting fiber run up the leg whcih cured the issue. At the same time, I moved the equipment off the stand off and onto the leg but never had an issue. -RickG On Sun, Aug 2, 2009 at 11:34 PM, Tom DeReggi wrote: > My understanding was that an electrical field of about 10" wide from the > tower leg, was likely to flow down it, if ever hit. > One purpose of offsetting the antenna greater than 1ft out was to solve > that.

RE: [WISPA] Tower standoff
I'm glad you remembered the ground crew class at Camp Shagnasty during Katrina, and also how it worked in Florida after Wilma. I still have to remind my tower crews about this simple operation.
