Andy if you we're only looking for a response from Jack, then just ignore this response.
>i) as a pringles can makes a radio wave because of an electric current in the center of its diameter, could >the mast be causing a separate radio wave as the AC line goes up the middle? Could this affect my signal? The word on the street is that the only thing the Pringles can does in the now-infamous project is to provide physical support for the project's antenna elements. The can doesn't "make" anything, everything is "made" my the antenna elements. There are two reasons here that you shouldn't worry about your mast in this case causing separate radio signals. First, the AC line inside a mast would not act as antenna element or an effective radiator in the WiFi band (a range around 2.45 Ghz), since its electromagnetic (EM) power is at 50 to 60 Hz about a BILLION TIMES LOWER in frequency. Two, I can ensure you not to worry about AC somehow transmitting and causing unintentional 50-60 Hz EM noise in the intended wireless receiver. 50-60 Hz EM waves are SO HARD to transmit wirelessly that you WILL not do something like that accidently. A single wavelength at this EM frequency is thousands of kilometers in length, which is so massive it's almost funny. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andy Middleton Sent: Monday, November 03, 2003 1:29 AM To: SOCALWUG Subject: [SOCALWUG] AC power line on a mast Jack, Another little doubt over AC power lines and antena masts; Here we have 220V AC, but I suppose it is the same for my question; I have placed an AP 7-8m off the ground, just under the antena, and obviously I have to get power to it. Well I have run an AC cable INSIDE the mast ( i thought it would be easier) up to the AP, or rather just below it where the transformer to DC is placed. However, after not getting excellent readings for the AP, it has occurred to me that i) as a pringles can makes a radio wave because of an electric current in the center of its diameter, could the mast be causing a seperate radio wave as the AC line goes up the middle? Could this affect my signal? ii) it could be more dangerous than normal in the case of a lightning strike? although the antena is grounded to the enormous metal fence that it is mounted on, the power line goes from just below the AP to inside the mast and then to the residence at 10m where the power comes from. I am not really sure what to do about this 2nd point; maybe bring down the AP, or its transformer or is it safe as it is? Andy
