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

http://lactose.blogspot.com/2007/06/...prove-its.html

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

if anyone needs it)

i hope you dont mind that i posted here before the mouse was broken,
but i guess i am anticipating that by the end of this experiment it
will need repair.

What distance from the receiver is the mouse located?- Hide quoted text -

15ft away. in a different room. the wireless mouse in question is
designed to operate in the same desk as the receiver.

i am wondering where i should attach the antenna to the mouse.

If you can briefly explain why the receiver is in another room I might be
able to offer a solution.

its to project a computer screen onto a tv.the tv out wiring was
catered for in the wall but i had planned to use a wireless mouse to
control it.i noticed the tv out wiring serves as a sort of antenna
itself.if i hold the mouse beside the tv out wiring it works.but i
would have to operate it at floor level.


more info on mouse:i think it runs at 27Mhz. there is a little can on
the underside which has 27.045 on it. the current antenna laid on the
pcb is shaped thus

The antenna starts at T4 (transistor 4) goes past C9 and C19, and then
forms a spiral loop on the PCB. No clue what's on the other side of
the board or whether there's a tuning capacitor. The solder blob near
the center of the loop, to the right of the feedthru, is possibly (not
sure) a 50 ohm tap.

Incidentally, you might want to fix the shift key on your keyboard.
