Dustin, While I haven't done any current work with the 2 foot Gabriel professional series I've been hearing enough good stuff about it that I ordered one to play with and see if it worth deploying. So far I like the Gabriel antennas. However, I am starting to see a pattern where the various

Tom, DSSS modulation is a single-carrier modulation scheme, BPSK operates much in the same way as DSSS which usually are much more robust then other forms of modulation because they seem to run like a single carrier modulation schema's. The neat thing about BPSK is its ability to take

As you start to walk up the modulation line you definitely need more C/I, but you also start to loose the ability to use full power out of the radio. A small bit of trivial regarding this issue With higher order modulation schemes, the EVM (Error Vector Magnitude) can be so high that even on a
