The ,

Web site has a Long Warning Information about using the CM7777 preamplifier in strong signal strength areas.

The reason for the Long Warning Information is.

We Live In The Amplifier Time Period Here On This Planet.

Amplify this Amplify That , Amplify and Amplify and Amplify and Amplify ,

Slam the Juice to It !! , Pump it Out !! .


Some Practical and Useful Information.

When the NM(dB) Signal Strength of All of the receivable Tv stations channels are in the Low Teens and Less , and the reception is blocked by terrain , then I Begin to Think about a stronger preamplifier such as the CM7777.

The CM7778 or 10G201 and other low gain amplifiers are better for your reception situation.

Most of the Tv station/channels at your reception location are moderate to

strong signal strength and are , LOS=Line Of Sight , no terrain obstructions.

This following information about antennas is Important.

Antenna Gain , a Bigger Antenna , Collects More Signal , Collecting More Signal

is Better then Trying to Amplify a Weak Signal from a Small Antenna.


Yes is true about Multi-Path and antennas.

The DB8e antenna is designed to reduce the reception of multi-path to a


It is a Trade Off.

The ability to receive Tv stations of different directions and the antennas

reception elements receiving reflections from different directions.

The alternative to trade offs is , install -->Multipul Antennas as in Many antennas.

Most of your receivable Tv stations are LOS so that is a reduction in reflections.

And also keep this in mind to reduce multi-path reflections.

Trees and tree leaves , plants and plant leaves , have an Negative Effect on

Broadcast Tv Reception.

Some and not all Negative Effects are.

Absorbing and Blocking Reception.

Multi-Path Reflections Bouncing All Around.

The Best Practice for Reliable Reception is to install the antenna/s at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception including your own , attic , roof , building.


The Digital Tv Tuner Computer can Correct multi-path signals to a certain point.

I recommend install the DB8e antenna , as a trade off antenna combination.

I think reception will be Ok.
