Recommend Do Not use the Winegard HDP-269 preamplifier.
Reason: Will most likely be To Much amplification when using the CM3414 distribution amplifier also.
Recommend use only the CM3414 distribution amplifier.
And might not even need the CM3414 distribution amplifier.
The HD7698P is a big antenna and as such , has high signal gain.
The group of Tv stations to the north-north east are Strong Signal Strength and will be received through the back of the HD7698P antenna.
My concern is that to much signal strength and amplification will over load the amplifiers and the tuners , resulting in bad reception of some channels.

Also old outside coax that has been exposed to the weather/water is most likely not good.
Recommend New outside coax and couplers.
Use the coax that has the Compression type connectors on the ends of the coax , not the old crimp type connectors.
To make double sure that weather/water does not get into outside connections wrap with ,

Also do not use coax 'rubber weather boots' , the boots take in water and hold the water at the connection , this makes for bad connections.
