Azimuth and true
Hi,
My address is here: http://www.tvfool.com/?option=com_wr...90383c9c5637ec It looks like I should be pointing at 156 for best reception for the majority of the channels in my area (northern NJ). What is the "MAGN" direction that's also being displayed? Which should I use? Does it matter which end of the antenna is pointing in the direction of the transmission? The narrow side or wide side? This image most closely resembles my antenna. http://imgur.com/XyCrtJR I don't know why my link doesn't work :-( Please see the image here: https://imgur.com/XyCrtJR |
MAGN stands for Magnetic North. That's where your compass will point to. You can use that to aim your antenna.
True north is not the same. True north is what is shown on maps, so you have to adjust for something called magnetic declination if you want your compass to point to true north. This declination changes constantly so yearly adjustments need to be to compensate. |
Thanks so much for your help. I had forgotten all of that :-)

If I may, while knowing the difference between Azimuth and true
is important, aiming an antenna for the best signals overall is really what matters. You may find that a few degrees either way may provide a better signal. Also, the tilt of the antenna can also contribute to improving the reception. Pointing the small end upwards slightly can really make a difference! |

Is there a better way to be more precise? Also, while the majority of the channels are southeast (169 or so), there are some that are a completely different direction. I assume it's just a matter of picking the majority of the channels that I want and sacrificing the rest? Thanks guys! |

"The problem I have is that the antenna is on a 10' pole - I can really only visually adjust it based on the compass settings from the app on my phone.
Is there a better way to be more precise?" If your television(s) have signal meters, I would suggest you use them to find the best direction. At only twenty miles from your major stations, aiming with the Winegard 7694P is not that likely to be that critical. |
I like to get on the roof with a small TV or use my laptop with a USB tuner in it. Works really well for fine tuning the direction and angle if needed. Takes out all the losses from long cable runs, splitters, introduced noise, etc.
My neighbors think I'm nuts when they see me up there like that, but they are probably right. |
