Looks like a significant loss... : - (
Not sure what would be a frequency on my case. Verizon splitter says 1675Mhz (1.675 Ghz?). This frequency is not in the table, but even with 1Ghz for RG-6 there would be 6.1Db per 100ft. If we do linear math here (even though it might be not precisely accurate), it would be (6.1*1.675)*(50/100) ~= 5.1Db
Thank you once again.
