has anyone tried a DDRR antenna on LF

there is info on them in one of the arrl antenna books and I use one on
144 very small but appears to work as well as a 5/8 wave

appears as a small horziontal loop but radiates as a vert

most odd thing but works well on 2 meters

Hi to all.

 

I see that many questions are on the LF reflector about antennas on low bands, modeling and concerning the lobe formation zones (Fresnel, Fraunhofer and Rayleigh). On the way, that explain why IUT is using the E.I.R.P. as standard of power.
