Hi Joe,
I have been using these antennas for years and I did not have any problem. One of the main advantages is that they are not very heavy.
You can see a comparative of CP antennas at http://eb4dka.tk , into the "archivos" carpet there are several articles in relation satellites apart form the comparative.
The articles are in Spanish although you will not have any problem to understand the tables.
Surely at the end of the summer the Web will be in English too.
