I've been reading on other forums that some plugin USB antennas do a good job improving the WiFi performance on the FT3. The two I've seen mentioned are the Edimax 7711UAn (based on Ralink RT3070 chipset) and the Skylink 1504n (based on the Realtek 8191SU chipset). Supposedly they work plug and play if the WiFi switch on the FT3 has to be turned off. Can anyone on this forum confirm that these or any similar devices work?
