In which case you may need to power the preamps *not*\nthrough the cables.\n\nFood for thought. Or to let the technical arguments fly!\n\nCheers,\n\nPat N8PK-FM19\nMaryland USA\n\nhttps://www.dxengineering.com/search/department/grounding-and-lightning-protection\n\n\n\nOn Thu, Oct 20, 2022 at 10:19 AM Rich Gopstein <[email protected]>\nwrote:\n\n> I'm installing a pair of M2 circularly polarized yagis.
