[TowerTalk] Trifilar Winding Question

[Jim Hargrave]

Dick,

I have wound several this way. I have one on the base of my Screwdriver
antenna using computer cable. It gives you a real neat coil. In my case it
works very well. I used the heavy flat cable with #18 wire in it. I also
wound a SWR meter bifilar coil using the small stuff from an old hard drive
cable.
