Transmission lines 600 ohm vs 450 ohm vs 300 vs coaxial cable

WitrynaLadder line impedance's can vary from 300 to 600 ohms and is balanced since both wires are identical and are running parallel to each other separated by the ladders or windows. Amateur Radio transceivers are designed to work with an impedance of 50 ohms, so you must typically use 50 ohm unbalanced coax at the back of the radio. WitrynaThat means the 450 ohm ladder line has over 28 times less loss than the RG-58. Open wire line which is bare wire, generally copper, and spaced about 3 to 6 inches apart …

That said, it may be moot since it terminates into the dipole which is effectively a random impedance. The addition of another mismatch at the the coax/ladder line balun could make things better, or worse.
