I made some change to the antennas design, now the band is narrower. Such that they cannot cover the whole range of channels available on 2.4Ghz (2370-2510)

Therefore I had to make two antenna sizes. one "LO" (2370-2450Mhz) and one "HI" (2450-2510Mhz) to cover the frequency range better.

I also have many request of tuning to 2510Mhz, choosing the "HI" model ensure a SWR of 1.3:1 or better on that frequency.
