I had two preamps from which to chose because as a result of my previous ordering spree. I used the HDP269.
Only recently, I am getting some pixelation on channel 6 but, that may change.
When I ran the down-lead cable and ran it through the attic, I didn't have another run of cable for the rotor motor so I went to a local Best Buy and purchased what turned out to be a waist of money. The cable packaging said the center was "solid" center and appeared to be copper. But, when I hooked it up, the Eagle-Aspen controller blinked and didn't transmit. I realized, immediately, that I purchased what must be copper coated steel. I ordered another cable (solid copper center), online, for half the BB price. I am awaiting arrival.
The other new preamp that I still have is AP-8700. I thought about going to the attic and changing the HDP269 to the AP8700 to see if this will correct the Channel 6 issue. Also, Channel 61 has a low signal strength. Again, I don't have control over the rotor at the moment so I need to wait-and-see, once I have rotor control.
