Don_H,

Impossible to attenuate ahead of the amplifier, it's all built into one unit with the driven element.

The new design isn't "cheapened out". It simply is not the same amplifier anymore. It's actually a very good amplifier, it's just quite different.

There are two versions of the 7777: The "Classic" which was replaced by the "New" one in 2012. Other than their names and the metal shell of the amplifier, they have very, very little in common.

The red light is just the power supply indicator. That doesn't mean the amp is working, though. If you remove the amplifier (completely!) and signals improve, the amplifier has fried, it's not the...

No, it doesn't work that way.

For the power supply's run to the amp, the DC resistance, not RF attenuation, is the factor of interest. You have to know the current demand of the amp, the DC...

Both of the antennas tried are ineffective for VHF. You need an antenna with real elements if you want a good chance at your VHF channels.

Both are too narrow of beamwidth on UHF. He needs to be able to receive predictably from a 90 degree spread on UHF, which he already is. Therefore, UHF doesn't need to be changed.

There's no such model. Please check again.

You cannot use a pre-amp when signals are that strong. Might as well go outside and look into the the sun with a telescope at mid-day.



No.

If you ever plan on using satellite, it will have to be replaced. Satellite service requires excellent performance to 2.2 GHz.

You'd have to ask Belden directly about the other stuff.
