was thinking 600 meters,,, the info for 160 meters looks backyard ish

Hi Bob,
small is a relative thing on LF.
A DDRR with a perimeter of 0.25 lambda and a height of 0.025 lamdba is
indeed small on 144MHz, but on 137kHz the perimeter becomes 550m and the
height a respectable 55m.
Not a backyard antenna ...

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.
