[Lowfer] Antenna environment changes

[N1BUG]

Subtitle: Be careful what you do in the vicinity of your LF antennas...

I had a 14m length of aluminum tube (proposed 30 meter rotatable
dipole) laying on the ground just under one end of the top hat of
the LF antenna. Today I picked it up and moved it about 20 meters
away. To get it off the ground for mowing, I ran it through the
lattice of a short tower (9m) that is not at all under the LF top
hat. I placed it about 2m above ground. This caused the LF antenna
resonance to change so much I could not retune with the variometer!
It was quite a large shift in resonant frequency.

I then experimented with moving the piece of aluminum tube around.
It seems I can lay it on the ground anywhere I want with no affect
to the LF antenna. But put it one or two meters above ground
connected to another tower or mast and the LF antenna is drastically
changed.

I must remember not to move any pieces of metal around while the
beacon is active! :-)
