Lee,
Try mounting your loop horizontally instead. Look at the MFJ mag loop.
Can`t afford the MJF on a pension besides for £50, mine works as well as the
MJF probably better as i use copper tube, MJF use aluminium!! and mine was
£350 cheaper.........
Thought about horizontal and high but the neighbours object altho` my tower
has been there before they moved in.......keeping the peace i suppose!!.
By doing so, you will have a significantly lower pattern of radiation from
your loop. You can also use a remotecontrolled LC network to change
directivity of the mag loop without a rotor. However, it's simpler with a
rotor.
Yes, once again it`s the height.
To avoid skewed directivity from your loop, you can feed it with a
balanced,
dual gamma match. Combined with a RF trafo with a centre tap on the
secondary side ( antenna side ) connected to the zero point at the loop,
you get a more equal pattern of radiation.
I`m currently feeding with a faraday loop.....
Don't bother increasing the mount unless you have electrically conductive
objects nearby. A loop does not need a groundplane.
That`s what i thought.
As long as you can remotely tune and direct your mag loop, you actually
have
a rather good antenna. Don't listen to much to these who have acres of
land
and no neighbours but have fun making QSO's instead!
Thanks.
