Are counterpoises necessary on EFHW or random wire antennas? What’s the right length? Should you let your coax do the work — or add a dedicated wire?
In this deep-dive technical video, we explore the truth about counterpoise usage in End-Fed Half-Wave (EFHW) and random wire antennas. Learn how current flows, how impedance matching affects performance, and how to reduce common-mode current and RFI.
