I have this device that was supplied with my Hitec 555Rx. The message enscribed on the card states that up to 18 inches of Rx antenna can be wound onto this "bobbin" to lessen the amount of antenna wire that sticks out of the model. According to these directions, there is a proper way to do this with the winding done without any cross overs. I hope the picture isn't too large to deal with....

I have also seen loaded coil type antennae offered at the LHS. I found one here: [link=http://www.rcmodels.ca/product_info.php?cPath=27&products_id=66]72MHz Micro Antenna[/link]

I've had some interesting things "happen" while flying that others attributed to interference and the way I had concealed my antenna wire inside my models' wings.

I'm letting it all hang out now, without similar occurances, but I'm interested in these micro antennas as maybe a good solution for the smaller planes or scale planes that stay in close. I have no idea what range we could expect from these, but it might serve the people who aren't interested in big range.
