Greg_E is right. The D.C. resistance of the whole coil isn’t going to be much. Not enough to be concerned about..
Some good news if anyone hasn’t tried it yet. Solder will stick to it! This makes for a great connection..
If you look at the original SStran coil design, Only the lower portion is used in the adjustment via the taps. The upper portion is to create the inductance/reactance necessary in the circuit..
What if..
..We stretched the Slinky out as far as gravity will allow and gave the windings a light coat of clear varnish or something to insulate the windings from each other. Now the top 1/2 to 3/4 of the Slinky could be bunched tightly togather on a form of some sort or tied with tie wraps. This should produce plenty of inductance/reactance without the windings shorting togather. This leaves the lower “Free” portion for adjustment.. Without taps! The area involved would be less than 2 ft. in length..
Again, It’s a thought.. Comments?
