Typically the CATV splitters are marked 5-1000 MHz or similar. I've
often wondered how much rolloff there was beyond the basic 3-4 dB down
at topband. I have a Clifton that I built myself, but have not been
able to achieve the insertion loss and isolation specs - which may well
be my fault.

I use a couple of old CATV splitters for general purposes around here
and can't measure any excess (more than 3 - 4 dB) loss from common to
either port.
If you want a known good design to build some of your own, try:

Can anyone point me to a design for a splitter for sharing a Beverage
antenna between two receivers? This is for Field Day so these are not
optimized Beverages by any means.
Just want to allow the 80/40M stations to share antennas. Nothing fancy.
My thoughts are to just use a CATV "2-Way" splitter at the output of the
Beverage matching transformer and run separate feed-lines to each radio.
I'm pretty sure these things work down to 1 MHz but have not measured
them. I can use the pre-amp in the radio (K3) to compensate for the
loss.
Thoughts?
