Re: Loop Wire Spreaders
Hi Tony, Russ and Farmerik,
These are very interesting comments, especially Tony's Afro-comb suggestion :-)
I've had good DXing results with 3/8" spacing on the PVC loops up to about the 4' (side) size, but since it's easy to use wider spacing when there aren't so many coil turns, 3/5" spacing was used for most of the larger loops here. With only 4 coil turns on the 9' PVC loop, it was easy to cut 1" spacing, which still made the pipe length only about 6".
The problem with wide spacing on the smaller loops is that your loop spreads out excessively, working against the compact design objective. If you really want better DXing performance from a tuned passive loop, it's probably better to move up to a larger loop, rather than trying to increase the spacing between the coil turns.
