Ladder-Line-Fed Antennas

High-efficiency multiband wire antennas that use a ladder-line section as an impedance transformer for broad, practical coverage with manageable total span. Ideal for modest lots, portable masts, and permanent installs.

Compact spans, real coverage

Example: ZS6BKW ~88 ft total yet covers 80–6 m (ATU on some bands).

Friendly tuning

Trim wire ends and keep ladder line near spec (~40 ft) to pull bands into a comfortable tuner range.

Scales with your station

Choose 500 W / 1.5 kW / 5 kW baluns. Upgrade later by swapping the balun.

Quick setup checklist
  • Center support ≳ 30 ft, ends ≳ 15 ft; total angle 120–180°.
  • Run ladder line vertically/clear for ~40 ft to the coax-interface balun.
  • Weatherproof junctions; add a CMNF at the radio to reduce braid-borne noise.

Tip: Pair with a MAXI-CHOKER™ at the feed-point (where applicable) and a CMNF at the radio for a quieter station.
