Get More Bandwidth by using a better Cable splitter

Thanks to the thread in here: the threadstarter found that his cable splitter was rusty, and changed it with positive results - more bandwidth.

That got a discussion going. And sent me shopping. Here's what I found.

Most cable splitters have these attributes:

• Frequency: the best are 0-1000Mhz, but what I could easily find was 5-1000MHz.
• dB loss: Signal loss for 1-Split-2 and 1-Split-3 is 3dB, but Signal loss for 1-Split-4 is 7dB.
• Isolation: some of the splitters have electromagnetic noise isolation, ranges from 80-120dB, I bought the 120dB one.

There is also a proper connection method: this post details it well:

To achieve a 4 way split, it is advisable to get a 3 way splitter together with a 2 way splitter, rather than to get a 4 way splitter.

4 way splitter will result in at least a 7dB drop in RF signal stregnth to each of the 4 taps. By using a 3 way spliiter, you at least get 2 taps with a 3.5dB drop. My recommendation is to connect your modem to one of the 3.5dB tap, and connect the 2 way splitter to the other 3.5bB tap, together achieveing a 4 way split.

My results? I'm happier with my optimized connection than before. It's little trouble, so doing it gives you peace of mind and at least a psychological boost.
