Good for you Jay!
Couple of points:
1. My guess is that with a little more time, you would be able to peak the dish to 99 and that appears to be the max.
2. Since the geniuses at Motorola/Voom changed the signal strength scale so the usable numbers are between 70 and 99, going from 96 to 98 is more than what it appears.
3. Do not make excuses for Voom when they send these loosers to install, especially when they do not even give you the option of self installing.
Looking forward to hearing how your new dish holds up in drizzle and rain.
