Takedown Magnetic Loop Antenna

Having just completed the building of a magnetic loop antenna (MLA), and after successfully running tests with it in the field with my manpack, I am more than pleased with it.

Now having said that, I decided to make a second version of the MLA as seen here coming together.
The difference is that this second version has the primary loop built from thin wall tubular hi-tensile aluminum, unlike my first version that has the primary loop made from LMR 400 coax that was important to the portability of the first design.
Now I know you wondering what happened to the portability, considering that I built this version with an all aluminum primary loop.

Well if you expand the photo, and look closer at the circumference of the primary loop (especially at the top of the loop, at either side of the red cabinet), you may be able to spot the 9 segments that make up the assembled primary loop.
Yes, that's correct the primary loop breaks down into nine 12" segments, allowing the complete MLA to be very compact in its disassembled form, allowing the MLA to be stored in the accessory bag that attaches to my manpack.

For the moment you can see machine screws sticking out around the circumference of the MLA, however that will change once the work is done.
Once completed the primary loop will assemble and disassemble in seconds.

Here is the TD-MLA finished and in its takedown mode.....
