Hello,
Have a new WinRadio receiver, and am a bit concerned about protecting it's front end from possible damage due to ESD ElectroStatic Discharge, effects, etc. I do receiving only, and have an end-fed PAR antenna outside, feeding the receiver by about a 30 foot run of coax from the antenna. At the antenna, I have an ICE lightning protector, and a copper bar as a ground point, there. No idea if the ICE unit has a bleed resistor for dissipating any static buildups. Too advanced in years now to build anything myself incorporating Zeners, Varistors, or whatever, so would like to find, if you folks feel it's worth doing (?), a small box unit with bnc's on both end, that would provide good and safe ESD protection that I would locate indoors right next to the radio's input. Any thoughts or suggestions ? Brand, Model Number, or just forget as probably not needed ? BTW: Nice article on ESD at: http://www.ce-mag.com/archive/01/Spring/Lee.html Thanks, Bob |

You may have to replace the diodes if you get a discharge, but not until. |

ESD problems normally only apply to bare integrated circuit leads and things connected to them like pins on a card plugging into a computer motherboard. anything on an external connector like where you would connect power and antennas should already have sufficient protection for normal use. |

Hello.
The ICE unit has a toridal coil to ground so in affect the unit is at direct DC ground. IMHA this is the best ESDI protector around Dick Sharp KE5NCR On Tue, 04 Jan 2011 14:11:45 -0500, Bob wrote: Hello, Have a new WinRadio receiver, and am a bit concerned about protecting it's front end from possible damage due to ESD ElectroStatic Discharge, effects, etc. I do receiving only, and have an end-fed PAR antenna outside, feeding the receiver by about a 30 foot run of coax from the antenna.
