Hi Dec
I'm in the process of upgrading my antennae as well. I'm getting between 35 - 60 flights in "my flights", depending on the time of the day..
I had looked at the ML&S web site, however, AirNav mentioned they were in the process of rolling out a special antennae kit for the ANRB, so i decided to wait and see.
That was back in Jan.08, I'll give it a another week, and if no sign of it by 01/03/08, I intend reverting to ML&S. However, all suggestions are more than welcome.
Another member on thos forum, I think it was "Piper Pilot"suggested using a high Gain whip, without the pre-amp.
Regards
