First, a small meander like you described would be fine. You'd never
notice the difference.
Second, you'd have virtually no change in directivity or S/N of the
array with 200-foot spacing on 160. You can read about this on my web
With a 500 foot antenna and 200 foot spacing, the best case receiving
improvement at 25 degree wave angle would be about 1dB over a single
antenna. That's true even though signal level increases about 3dB.
Here is the 160 meter directivity (not GAIN) referenced at 25 degree
signal arrival at each spacing:
One antenna =8.8dB
200 ft spacing = 9.7dB
300ft spacing= 10.6dB
380ft spacing= 11.4dB
Don't be misled by the absolute "gain" shown in the model, thinking
it means you will see that change in S/N improvement. The gain change
actually just reflects the addition of two signals with the same S/N
ratio from each antenna, and can be 3dB with absolutely no change in
receive performance. We are often misled by folklore into thinking
more absolute gain means better receiving.
