I ordered a RC helicopter. 2.4 GHz
The specs says it has a 120 ft. range.
It is reported that the range can be extended by lengthening the antenna.
The antenna length is 3.25 cm long.
Would increasing it's length to 6.5 cm increase the range ?
Do I need to solder the same diameter copper wire to it ?
Thanks.
I found this.
What do you think ?
The length of the antenna on a typical 2.4GHz receiver is 28.8 to 32 mm lon g, most are about 28.8 mm. The antenna is that length of bare line often at the end of a longer coaxial cable to move the antenna farther out from the receiver. Yes, the length of this is somewhat critical and can greatly var y the distance that the signal can be reliably received. To long can be jus t as bad as to short unless you can accurately make sure it is some odd mul tiple of an electrical quarter wavelength; i.e. 3/4, 5/4, 7/4 etc. Note tha t electrical wavelength can be different than a simple measurement as it de pends on the velocity factor of any coax or other line involved.
