in practice it's invisible and. being a loop. it also helps taming the QRM

if one doesn' t feel comfortable in winding the voltage BalUn, the NooElec 9:1 v2 will fit, just ensure to use low loss coax (e.g. RG6, avoid the RG58 !) and add 10 or more snap on ferrite rings to the coax, near the antenna feedpoint, to avoid issues with Common Mode Currents and the noise they introduce
