[time-nuts] Antenna for t-bolt

[shalimr9 at gmail.com]

The elevation angle filter is based on the satellite position, not the actual direction the signals come from.

If you have reflections and multipath, but the satellite is otherwise high in the sky, you are out of luck regardless of elevation angle filter.

Of course, the higher the sat, the less likely you will have reflections from roofs and such, so it is definitely not useless, but it is not the same as having a good antenna in the first place.

Maybe, but there is a software aspect to the filter.  You get to select the 
elevation angle.

I don't remember seeing any specs about the filtering angles of various 
antennas.  Has anybody seen something like that?
