Default is there really Digital splitter?

I have a leviton splitter (passive) that came with the structure media, that was before DTV times..

I am sure it will work fine for the OTA DTV distribution but what do the higher Gz rated splitter do?

I just want to make sure the older style splitter is not going to cause alot of attenuation.

If a splitter splits 5 ways does that mean the signal is divided and weakened all the time or only when multiple TV sets are actually on?

I think these are the specs, does it sound terrible?

6-way 1 GHz Video Splitter:

Die-cast housing and printed circuit
construction.


6- way Splitter Specifications:
Insertion Loss: 10.0dB - 12.1dB
Return Loss: 6.5dB - 23.5dB
Isolation: 28.9dB - 37.5dB

Default In a word... no.

Splitters haven't changed much at all in decades -- IOW, well before the DTV standard became final. You may be able to find a new splitter that performs slightly better, but in all likelihood the difference wouldn't be noticeable.

"1 GHz" refers to the frequency range it can handle. It means the splitter is fine for OTA use, but not for satellite service, which uses higher frequencies.

Yes, the splitter loses that much signal, regardless of how many TVs are connected or turned on. In fact, it will lose even more signal than what's stated in the specs if there are any unused port(s) on the splitter after all TVs are connected to it and those ports are not capped with coaxial terminator(s).

For that many splits, a good, low-noise distribution amplifier or antenna pre-amplifier installed before the split is frequently needed.
