re: KR1ST antenna real world feedback--- i just built this antenna last week. i saw an improvement of 4- 5 S-units signal strength (generally) and a great increase in readability. also some reduced noise level. i would enthusiastically recommend this design to anyone now using only an swl longwire. i know it works very well.
