WebDec 11, 2024 · The counterpoise that makes the vertical monopole behave like a λ/2 dipole on a HT is the operator’s body. It is capacitively coupled to the ham’s body through the plastic case and metal shell around the RF circuitry. This indirect counterpoise coupling is not only weak but also highly variable and unpredictable. new mexico maps 3d
