RE: [amsat-bb] Dish aiming

["hdefelice" <hdefelice@xxxxxxxxxxxxxx>]

While it is very true that increased gain = decreased beamwidth, increased 
gain also means increased link margin. The added gain of the larger antenna 
allows it to be off pointed more than if every dB of gain was required. 
This is the reason those darn little DSS antennas are so difficult to 
align. As a rule, the pointing accuracy needs to be better than the 3 dB 
beamwidth of the antenna. Some amount of inaccuracy can be compensated for 
by adding system margin.
