O.T.A. television yagi question,

<< < (3/3)

CaptDon:
Preamp is 6 inches from antenna and all feedlines are RG-6 low loss foam from antenna all the way to the T.V. The weak station is generally good during the winter when no leaves on the trees and as mentioned snow cover on the ground does increase signal strength by about 1 to 1.5 dB, BUT when the elements have snow build up resting on them (recently nearly three inches) the gain on the weak station increases by nearly 3dB!! I guess the strong stations also see the increase but I didn't specifically look at them. I am surprised to see pixelation when the signal is in the -79 to -82 dB range measured with my TinySA who's scale is dBm @ 50 ohms. I have one adapter in line, it is F female to SMA male to mate with the TinySA.
