Unun 1:64 Variable For End Fed Half-Wave (EFHW) antenna 100+W - Alternate wind

Description

Unun 1:64 Variable For End Fed Half-Wave (EFHW) antenna 100+Watt - Alternate wind. I saw this interesting alternative winding scheme on a webpage accessed thru Reddit Ham Radio group. It employs a 3:24 turns radio which equates to 1:64 impedance ratio. Vary the ratio by +/- black turns or use available taps. Real world tested to confirm how the attending data equates to performance. Refer to the normally wound 1:64 unun I recently listed for equivalent performance details. Uses same core size and type, FT140-43. #18 wire. 100pf, 3 kv cap included for enhanced performance on the higher bands. BNC connector available on request.
