That depends upon the length of the feedline: cheap copper plated satellite RG6 has a *lot* of attenuation at 2MHz, as much as 3.6dB per 100m
We have a 750m coax feed to our beverages and attenuation DOES matter on long feed lines. We had ~ 25dB ! http://lists.contesting.com/archives//html/Topband/2011-05/msg00027.html Caveat emptor.
