Check your mod levels over time to make sure they are switching gears down
to lower mod levels during noise intervals. Also definitely turn off noise

Generally speaking, when the FCC specifies antennas they are more interested
in the pattern than the gain. Specifically, they have a beamwidth and

For example, It can be beneficial to cache sites that are geographically far

You can find all kinds of information if you do searches on squid. It's
