I am about to build a flag for MW and low-band amateur radio. I had to watch your vids to see how well they work. I am very impressed. From my modeling and simulations, however, I have found that having the feed and resistor in the center of the vertical elements works much better. From my model, I find that I should be able to get a front to back of better than 40dB from lower MW to about 7MHz; with a peak of 64dB around 3.8MHz, as this is the band that I want it optimised for anyway. Cheers.

@kc8ntp hi the slinky flag was just an experiment to see if it was working. i am back using the normal flag and fed at the center of the vertical and same with the resistor. conditions of late have been very poor and not a patch on last season. check out my blog for what i am up to ... the link can be found on my channel page

Interesting antenna. It's small enough that it could be put on a wooden frame, outside, and turned with a rotator! Hmmmmm ..... LOL!

if you open up the resistor you get 2 directions with it ie the figure 8 pattern then you tweak the resistor and it goes back to the cardioid pattern so i dont really need rotator as i am only interested in the west and east thanks for watching happy new year ... david

Great video David I like the slinky flag antenna it seems to be working great for you..the perseus receiver looks interesting does it pick up much interference from your PC I have to have my pc off to listen on the MW bands I think it is the power supply on my laptop that makes the interference. But good demo David cheers.....oh and congrats to Ken for Dxing Alaska! cheers and beers Mark
