I have put this line in /etc/modprobe.d/options (using Kubuntu 7.04)
options dvb-usb-dib0700 force_lna_activation=1 will both cards use that or
do I have to do it some other way to get it on all cards?

I have had a amplifier for while but changed to better one this weekend. I
have it mounted close to the antenna and it supports DVB-T. The server is
placed in the basement and it's about 25 meters from the amplifier. I have a
1-2 splitter at the server and will test without that since cause 3.5 dB
reduction

Don't rely on an external standalone DVB-T receival to find all channels,

OK, I am my own "building administration"  so I can do whatever I need/want
:)
