The extending of the coiled antenna inside of the RF extender was very unofficially explained to me by the people at philips during CES supposedly if you straighten out the coiled antenna and pull it to the outside of the case and keep it straight with something like the antenna holder for an RC car I'm going to try this with a marantz piece this week and will let youy know how it goes. A place for an antenna extension on these things would be nice just so we didn't have to do R&D on all these products for these companies,,,,,hey a quick thought do you think we could bill for our time to fix a manufactures problems?
