I intend to order the MFJ-1780 Box Fan Portable Loop.
I'd have it on order already but they are closed on the weekend.

It is a magnetic loop configuration, and the box is
a composite wood product covering an aluminum frame
which forms the loop.

My interest was piqued by my need for a magnetic loop
which I hoped to build, but by the time I can collect the
necessary parts, I decided I could purchase the MFJ-1780
for the same money.

In particular, I became very interested because it has
a Remote Control which carries the signal and power through
the coax, and in particular a neat looking motor driven
capacitor for remote tuning.

One chap has had his hanging in a tree, with weather
protection provided by a plastic garbage bag. It has
been up for almost six months and come spring he intended
to inspect it for any possible damage to the motor/capacitor
assembly due to moisture.

I suggested he might want to spray the capacitor/motor
assembly with WD-40, and he in turn suggested that there
could be implications due to the high voltage (in the order
of Kilovolts) across the capacitor, and perhaps a silicon
spray might be better.

I could homebrew a loop easier, but collecting the parts
necessary for the loop (e.g. a motor and vacuum variable
and such. let alone the remote controller) is well beyond
my capabilities as I am somewhat handicapped and no longer
have more than a small desk for a workshop.


Has anyone suggestions or comments (except MFJ = Mighty
Fine Junk) on this matter. Any assistance would be greatly
appreciated.

Thanks
