The antenna in the origin was an OCF (off center feed dipole), of 21 meters; this is a simulation of the OCF (not linear loaded):
The OCF was too long for my balcony, so i tried a new configuration: now it is a 23,4 OCF dipole, linear loaded. The center of the cable is attached to the vertical part, that is the aluminium tube.
I use it with my micro Bitx, with 10 Watt on 40 m, 3 watt on 20 m and 1,8 watt on 15 meters with very good result (in 20 m and 15 meters i work QRP, with less of 5 watt !!!). I use a Kenwood AT-130 antenna tuner to tune it.
In the next post i will report my testing.

Very ingenious! I look forward to the results of your testing. Mel, W3PYF
RispondiEliminaYes, 47 countries worked with 1 watt; also Canada and Usa; 7 countries worked with 100 milliWatt, in Europe.
