At first I tried a 15dB amplifier, attached before a 4-way splitter, the symbol quality went WAY down. I imagine it's because it's clipping. Without an amp, the signal strength goes way down and the TV is unwatchable. The signal is great (can get all channels) with a direct connection, and splitting into 2 seems ok.

What's the ideal situation to split a single signal into 4 with losing as little signal/symbol strength/quality as possible?

I own an HDHomerun so I was able to do to the test on percentages.

Amplifiers and splitters.

First, normally a preamp at the receiver is a waste of time and money. If you have a noisy signal it'll only give you a strong, noisy signal. IF OTOH when running the cable to the set with no splitters and the signal is good, *then" an amplified splitter should help if the signal shows up weak when split out to multiple sets. Unless there are some strong stations that could/would cause overload the best place for the amp is at the antenna. Amplified splitters are good only if they have a good signal at the input. Like the amp at the receiver, if you feed them a noisy signal you just get a lot of noisy signals out.

Use a low noise distrabution RF amp before the splitter. Motorola has a very good one: http://www.amazon.com/Motorola-484095-001-00-Signal-Booster/dp/B000066E6Y

I actually tried just that MOtorola amp. It drops the symbol quality considerably, about 20%

Would something like this helP:

Are you trying to receive HD channels on all 4 splitter outputs?
If only on one then then try one 2 way splitter with one ouput connected to your HDHR and the other to a 3 or 4 way splitter to the other locations.
