extended wire antenna lengths

[soundscu]

I have an unusual application for XBeePro 2.4GHz radios, with a limited budget and odd physical construction. I would like to use an extended-length wire antenna to overcome these issues.

Understanding that the standard 1/4-wave wire antenna is 1.2 inches long, a full wave antenna would be approximately 4.8 inches.

Would it be ok to use a 3x wavelength antenna that is 14.5 inches long?

Thank you for your advice.

No. the reason for this is that your ground plane need to be proportional to the length of the antenna wire. Otherwise it will not function properly and your effective range could be greatly reduced. Instead, it would be better to use the U.FL version of the radio and either remote mount a dipole antenna or have a custom antenna created.
