    Yes, we're using a piece of Delrin for that exact reason.

    No it shouldn't be costly at all. We're currently making two more prototypes with minor adjustments and they'll be sent half-way across the word for heavy field testing.
    We want to make sure they'll work in any conditions!

    In fact, if someone is the owner of a Chameleon Antenna magnetic loop like the CHA F-LOOP (Plus), CHA F-LOOP 2.o (Plus), CHA P-LOOP, CHA P-LOOP 2.0 we might need some testers soon.

    Ouch.

    Pre-product is not product. Give the guy a break.

    I believe that the only thing that looks out of place, in my opinion, is the Clamping system. Get that redesigned and you got a customer. ;)

    The clamping system is at the base of the design because it can be used will all current commercial portable magnetic loop. Designing a proprietary clamping system will increase the cost for nothing.

    Not that hard to make... Oren Elliot air variable has 6 to 1 gear ratio & slip clutch.. No need for end of travel switches. Normal range for the air cap is about 18pf to 387pf. If you can see in pic... I added a relay & cap to kick in to give it 397pf to 766pf....
