I'm not sure where to post this so I'm starting here, HD Radio seemed to be the closest fit.
I've got four Russound MCA-C3s and I'm using the built-in FM tuners. I'm trying to decrease or eliminate static on 107.9. The house is three stories with attic space on both the second (attic over the first floor) and third floors (attic over the second floor) and a small space (~2') above the third floor. The system was installed with a half wave whip antenna mounted horizontally in the second floor attic space pointed NE. I've attached the info from a report I ran at fmfool.com
I don't know much about FM, but I've been doing a lot of googling so now I know less then I did before I started
I've tried adding a 10 dB amplifier before the MCA-C3s with no change. I'm considering any or all of the following:
a) orienting the existing antenna vertically
b) moving the antenna up one floor to the third floor attic space
c) adding a second directional antenna pointed in the direction of of the 107.9 transmitter (I'm not sure how effective this would be since the fmfool data says the path for this channel is 2edge)
d) adding an external receiver and using it instead of the built in tuners.
e) replacing the existing antenna with a better antenna
f) something else I haven't considered yet...
One thing I read said that a half wave antenna is designed to have the other half of the wave reflected off the ground plane (like the hood of a car) since this antenna is mounted to a 2x4 roof support I assume there's no ground plane, but I'm not sure what that means.
Any help and further eduction is appreciated!
