Hi Frank,
The problem with a common ground for multiple Beverages is that it isn't really "ground" at all. Inevitably it has significant resistance, The signals received by your eight Beverages will cause significant current flows through perhaps fifty ohms of RF resistance in your "ground" rod. The voltage that results from the current flows from eight connected Beverages will appear as unwanted signals on your selected Beverage, significantly degrading its directivity. One solution to this problem is to use eight ground rods spaced at least 3 or 4 meters from each other. Another solution is to use relays to connect only the selected Beverage to to the ground rod and disconnect the other seven. 73 Frank W3LPL ----- Original Message ----- From: "dl8yhrfrank--- via Topband" <[email protected]> To: [email protected] Sent: Friday, March 18, 2016 7:16:21 PM Subject: Topband: 1 center point to ground all 8 beverages?? Hi all.. 160m season over soon... so think about new setup off beverages..found out a new center feedpoint place where i can connect all 8 beverages with just a few meters coax to a antennaswitch..annyone knows if its possibile to connect all balun ground connections just to one center ground point off a cuppertupe some 2.5m in the ground? Ore does each Beverage need his own ground? Anny info vy welcome.. vy 73 Frank _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
