Wondering if anyone has tried flat ribbon cable for winding spiral coils. Could split out number of conductors depending on peak current wanted. 10 conductors same as awg18. Price/coil wouldn't be to bad. Easy to wind coil. Any thoughts pro or con?

Years and years ago I made an antenna out of ribbon cable. The two ends soldered together but offset by one conductor so you had a spiral
for the life of me I can't remember what it was for (SDR possibly)let alone how well it worked.
I know the CAT5 cable done the same way can preform worse than expect if
1 you use cheap China cable
2 or you use too much solder on the joints -
do you hope to decrease the dielectric permittivity if take flat cable? i think no. you decrease dielectric permittivity if wind the coil IN AIR.
ie thats type we recall BASKET COIL either FAST COIL.
dielectric permittivity of vacuum = dielectric permittivity of air. PHISYCS in the school.Comment

Been winding my coils with awg28 magnet wire. awg28 solid can look like a target at short sample delays and limits peak current to 1amp maybe a little over. Trying to find wire with small strands that I can parallel enough strands for desired peak current to wind a spiral coil. Removing 4 conductors and winding a spiral(radial?) coil with conductors vertical and connected in parallel should give a coil rated for 4 or 5amps with awg36 strands. Maybe there is a better option to try?Comment

My error. I want to increase the current carrying capability. Conductors connected in parallel so probably not a spiral coil maybe radial coil?Originally posted by Koala View PostComment
