Alex/Stefan et al,

If I understand Alex correctly he is using a series of well engineered= semi-loops with 3 sides elevated low loss loop (15mm diameter aluminium) an= d one side earth electrodes. Results certainly confirm that it works well.&n= bsp;

In my case I managed 250km on 136kHz WSPR with= just 10-12W from the PA (low uWs ERP) with just the earth electrodes and vi= rtually no loop in the air at all. I am CONVINCED that the structure Alex is= now using is worth more investigation as he has clearly demonstrated how ef= fective it can be.

I have 2 ants n= ow: WsLoop and EsLoop
WsLoop - Western direction sLoop -&n= bsp;North-West(N-W EU-W-VE) and to South-East(VU-VK6/5/7-ZL4)= lobes (some photos of WsLoop is on

= Height above ground are 8-18m and far point of EsLoop is abt 22m
I= believe sLoop is semi-Loop or semi-earth Loop :-) 

SS>Can i a= sk what is the power? :-)

Russian power's limitation o= n LF is 100w Output now :-(
... but soon the Russian authorit= ies of communication will allow  1W ERP - I'm pretested here
I h= ave now abt 200w Output in W/EsLoop - currents in ant are 2.6A(W) and 3.6A(E= )

I'm using since March 2013 Class D audio PA on 136
