Dear LF,

let's describe yet another kite-ant design for 9 kHz. Let it be trianle
loop elevated by a kite up to 100m. Base of triangle (parallel to earth) 
assumed as 200m, height -- 100m, wire -- 2mm diameter cupper wire. Then DC
resistance is 2.8 Ohm. There is some skin-effect (not strong)  with such a
wire. This is why let's increase resistance to 5 Ohm. With such an ANT one
should supplay ABT 18A into loop to radiate 1 mW on 9 kHz. This yelds 1.5
kW of TX PWR -- not too much. Advanance is that there is no very high
voltage with such an antenna and huge coil is needless (but condensor
should be used). By the way similar  ANT easy can get RU6LA without a
kite:-) Are you there, Ed?
