Amidon Balun 1,5:1,
Amidon 50 ohm to 75 ohm balun helps you many way. Usually dipoles for lower band ( 40 - 160 m ) are not even half wave length from the ground. Dipole impedance is the usually 60 - 100 ohm. This balun drops SWR and also noise, inteferenxce and TVI. Lightning protection is always better with ferrate balun.
