Yes, the coax are of, but you can do things a lot better with ladderline-feeding of antennas!

For example:

• Reduction of TVI and BCI.
• A dipole-antenna operates on all bands with a SWR of 1,0. BUT: the use of a balanced tuner is absolutely necessary to reach this standard.
• Following the lay-out of your antenna, the ladderline-feeder can ba a lightweight-solution compared to a coaxcable!
