I apologize for the ignorant, dumbed-down, misguided and non-fully disclosing information I have provided - on this board and off of it - regarding what I have done working the satellites over the past 6 months given the choices I've made about assembling a station.
Jim - Did I miss your response to the direct question I asked last night about what the gain figures for the Elk ought to be - or is that question too ignorant to be worthy of an answer?

Yes folks can make contacts with Arrow and Elk antennas because it is done every day of the week . . . . that is not the argument here . . . my comments have been made to give full disclosure of the several issues which seemed to be
