Title: Half Size Dual Active Delta Flag Arrays- Lankford
Post by: weaksigs on January 25, 2012, 1321 UTC

Take a few minutes and read Dallas Lankford's article on
Half Size Dual Active Delta Flag Arrays.

The article can be found at;
http://www.dxing.info/equipment/

The article also addresses an Un-amplified version.

This will be excellent mid day or lunch time reading!
I would appreciate any comments.

Thanks Dallas!  ;D

I wonder if this can be adapted to TX?

Peace!

I'm considering a an indoor flag or pennant type antenna for my apartment to supplement or replace the homebrewed loop I've used for the past couple of years.  Some UK DXers have put up YouTube videos showing their indoor flags and pennants, and they seem to work well for MW - not sure about HF.  These designs seem to be directional enough to null out competing stations on the same frequency.  It'll be interesting to see whether it's directional enough to null out the worst local RFI as well.
