LF
No sigs visible in JA from EU last nite at the peak time,
around 2150 z. The JA grabber moved freq so not possible to check at 0740z the
other peak time.
I think the antenna used for transmitting has some
influence on the launch angle and distance covered and likewise the type of
antenna at the receive site. ie low or high angle.
A vertical TX antenna system as high as possible would
produce low angle signals, preferable for long haul DX, and low horizontal
wires, loops etc would produce high angle, ideal for short ranges but not ideal
for DX although the odd time high angle also does the trick. Large vertical
loops fed correctly at the side produce low angles but small vertical
loops relative to frequency ie LF might be difficult to evaluate.
