In the case of the MoCA filter installed on the antenna line, yes.Is not broadcasting back through the antenna the only reason to need a higher dB filter?
A typical amplifier would likely allow MoCA signals to pass, though perhaps the aggregate attenuation of the 40 dB MoCA filter and amplifier would put you closer to or over 70 dB total.I'll likely need an antenna amplifier (currently using one now, in fact), and I read MoCA can't back feed through an amplifier anyway.
It's not that critical, really. I'm confident that there are a LOT of people using 40 dB MoCA filters on their antenna line.
