Hallo Frank,

have not had a look at the files you mention (but would love to see a
copy). However, exactly the sample you mention would interest me, too,
because that is exactly the configuration I use currently on 136 kHz.

Well, not yet 6 top load radials but 5 only. But I plan to increase the
number to 6. At 45 degrees inclination, what is the optimum length? 

Currently I have an efficiency of minus 35 to 37 dB (I measured my ERP to
be 30 mW in up to 3 miles distance), does this match with the calculations?


Best 73, happy Easter Holidays!
