Re: LF: Re: MiniWhip antenna

[jcraig@mun.ca]

Dear Group,

Today I listened to my Op32 transmissions at a remote site with a
miniwhip/preamp/FT817 with internal batteries.  There was 1.5 m of coax on 
the miniwhip.
Some qualitative results: The higher the mw, the stronger the signal.
The signal was weak when the mw and rig were at the same height, but there
was still a signal when the mw was below the rig.  The sigs were weakest 
when the mw was on the ground.  I think mw is responding to the field at 
the height of the whip (capacitive coupling) and the potential differencew
between this and the capacitance to ground of rig and feedline.  Does this
make any sense?

The TX is on 137.555 kHz OP32 0.5W erp from the tower. A 100w dummy load
connected to the 100m wire gets quite hot in short order!
