It's interesting that when you adjust the null of Holland to a minimum, several adjacent-channel carriers also null out. This is visible on the display and is probably due to the antenna being broadband and adjacent-channel carriers being roughly in the same direction as Holland-1008.
Flag and corner fed/terminated loop antennas seem to give better nulls than tuned figure-8 loops. Just aim and adjust. I love that slinky design. Does that provide much noticeable gain over a straight wire?

hi for some reason the slinky flag "seems" to have a tighter null than the normal wire one. also there is a little more noise with the slinky flag which i think is just to the fact that there is more wire in use ie my west flag is 7 feet high and about 15 feet long but on the slinky flag i use two slinkys which are original usa oneswhich are about 70 feet in each one so a big difference so it lets me get alot of wire into a small space but dont put the coils too close together cheers david
