Using normal -7DB splitters causes too much signal loss. What I need is a low loss, high bandwidth COAX cable splitter.

I've been doing that for a few weeks now. Thanks.

How many directions are you splitting?

Each split has a fundamental loss of -3.5dB, since that corresponds to slightly less than half power.

If you split 2 ways, you can get a -3.5dB splitter for both legs
If you split 3 ways, you can get a -3.5dB.-7dB.-7B splitter or a -4.5dB,-4.5dB,-4.5dB splitter.

For a nice full bandwidth 2 way splitter, monoprice works. If you want an amplified splitter to get little-no signal loss, check partsexpress but they can be expensive.

Exactly. There is no getting around this.

However, with the advent of digital broadcast signals...signal amplifiers now make much more sense.

I agree, all passive is the best way to go. I have a short and medium range outdoor antenna that was originally used for FM radio, I am splitting the signal two ways: One goes to the radio and one goes to my Sony (ATSC) KD-34XBR960. However, spiting the coax gives me no signal on either device. I have dozens of various splitters lying around, most have different specs of loss and bandwidth (don't use splitter with bandwidth higher than or out of the range that you need).

Oops, I over looked the second sentence and only saw the first one. :D

a regular 2 way splitter (-3.5 dB, often marked 4) rated for 860 - 1000 MHz should work. it should be grounded before entering the house, or at very least ground the splitter. i recommend against the use of a surge suppressor/power strip thing for any signal cable.

does the antenna work with only 1 device connected? with and without the splitter?
