[amsat-bb] Re: Commercial Mode L Antenna sources

Ed,

Thanks for the info. I can put ~75-80 watts to the antenna, so when we get another HEO, I will have a shot at it. The "extended" helix my friend got is about 15.5 dbi CP gain. The M2 is rated at 18.4 dbd (20.5dbi) linear. So when you put all the conversions in to get it to apples to apples, you can eat the 3 db CP to linear mismatch and the M2 is still ahead a couple of db.

I have worked mode-L on all the past and current birds with different antennas and amps, so it will be interesting to see what the future holds.
