Yup, there is no way to fake a real antenna. :) Too many people confuse a high return loss (low SWR) with the "quality" of an antenna, or even make the mistake of "tuning" an antenna to have some arbitrary impedance like 50 ohms, regardless of the effect on the resonant point. A 50 ohm resistor has great return loss, but I've not made too many DX contacts on them. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
