an external Aerial to my PC mouse

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

(i can upload a hi res one 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?

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

Ok here is what I would do. I would go with a wired USB mouse and a powered hub. Each segment will allow up to 5 meters length cable for a total of 10 and that equals around 33 feet.

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.
