Balun  1:4 (For Folded Dipoles or Wireman-feeding)

With 2 x 8 turns bifilar (PTFE-cable) this balun on a FT240-43 handles 1 KW. For better impedance matching a parallel capacitor 12 pF/1 KV for the coax input is recommended. here are 4 x 12 pF/500 V used.

With a Transmatch-Antenna-Tuner I feed a Wireman-cable for doublet antennas with very good results. See here
