To best use a long-wire antenna, the 9: 1 transformer toroid T200-2 red or T200-6 yellow
A 9:1 Balun For Your End Fed Antenna
End-Fed antenna it is wired as a so-called unun transformer unbalanced to unbalanced
Balun 9:1 su toroide
Each antenna has a characteristic impedance that, often, does not fit with that of the drop cables and the inputs of the equipment
