hi there,

i read an article(link below) on adding an external aerial to a PC
mouse to improve its transmitting ability using a twist tie to its
front

but it didnt improve its range. i figured you ppl here know your
aerials so i was wondering if you could give me some ideas to try.
this is what the mouse looks like (RF board is one on the right). thx

Sorry I'm late, we were away for Xmas.

One thing already suggested is somehow making electrical contact between
your body and the antenna terminal so your body acts as a larger
effective antenna at the mouse. I wouldn't worry about any impedance
mismatch between the RF portion of the mouse and your body, power levels
are so low you won't damage anything.

Another thing is making the antenna at the PC bigger, like maybe a full
wave loop of #36 magnet wire strung up the walls and across the ceiling
and coupled in to the dongle by wrapping it with a few turns of the loop
wire. Different orientations of the loop may give you better performance.
