Default MW loop ribbon cable?

Does anybody know the circle size for ribbon cable (.05" spacing)
tuning the MW band with 365pf var cap?

I have 10, 14, 16, 20, and 25 conductor ribbon cable (28 ga. wire)
so diameters for any of those.

There's always cut and try but maybe somebody has done it.

I have not used ribbon cable but have plans on the AMANDX site below for
a box loop......maybe it will work

Mark Connelly had an article online for a ribbon cable loop but it's gone.
Remember, Shawn?

Hi Ron,
I made one out of 10 conductor ribbon several years ago and the
diameter was around 15 inches.
The design was from Short Wave Mag. I recall.
Regards
Tom

RH,

1. The Portable 3 Foot Ribbon Cable Loop
This article describes how to construct a loop from ribbon cable.
GoTo= http://www.mindspring.com/~loop_antenna/ribbonloop.htm
"Introduction - One idea that has been suggested for constructing a
loop is to use ribbon cable, with a winding spacing of 0.050 inch, to
consturct the loop. I saw a loop antenna article at one time that
recommended the use of flat ribbon cable, and showed how to make a
loop by using the ribbon cable, offset by one pin, on two "D" style
connectors, and plugging together to form the loop. I have never seen
that article again, so I suspect it has been removed from the web. So
I thought I would resurrect the idea.

2. The Umbrella Loop Antenna.
GoTo= http://www.mindspring.com/~loop_ante...brellaloop.htm
"The Umbrella Loop Concept - I saw the answer in an everyday object
that just about everybody owns - an umbrella. Like my "ideal" loop, it
needs to have a large deployed shape, yet needs to be lightweight
enough to carry, and needs to fold to a compact form that is easy to
store. It needs to deploy quickly. It has many characteristics in
common with what I want for loop! But - could I make a loop antenna
based on the umbrella design? I cannot use umbrella hardware directly,
because it is metal. But - I found a way to use wood instead for the
supports, and a minimum of metal used near the center of the
mechanism."

NOTE: The WebPages = http://www.mindspring.com/~loop_antenna/

3. Superloop receiving antenna for 136kHz
GoTo= http://web.ukonline.co.uk/g3ldo/loop.htm
"About a year ago I made a receiving loop for 136kHz using computer
ribbon cable housed in plastic waste pipe."

Like said the capacitance gets to high, you have to Mobius wind or forget it
!!

No way to mobius wind a ribbon loop, Joe.
