My old 450-ohm ladder line, which had been in service for more than 20 years, was showing signs of deterioration-mostly in the form of cracking in the insulation due to the harsh Western Australian sun-and was due for replacement.

This innovative method involves using cheap vine ties (KiwiKlip) as feed-line spacers, offering a very affordable yet effective solution.
