Question B-006-004-002

What are some reasons to use parallel-conductor transmission line?

Correct Answer

It will operate with a high SWR, and has less loss than coaxial cable

Open-wire/ladder line has significantly lower loss per unit length than coaxial cable, especially at HF. It can also handle high SWRs without large additional losses (though a tuner is still needed at the transmitter).
