Yes, the signal is coming from that azimuth. The true azimuth is relative to true north, as on a Google map. The magnetic north is what to use with a pocket compass. At your location, the difference between the two is only 4 degrees. Some smart phones have a compass, but are often not accurate.
if I remember correctly about ten years ago if I wanted channel32 I'd had to switch ( different analog TV) to 31 and TV magically when to 32 that was a confussing time I think that was when channel 8 took over channel 32 I believe they both broadcast over near the Suberaro car dealership.
It is important not to confuse the real channel number with the virtual channel number. As I stated above, the real channel number is the channel used by the transmitter; the virtual channel number is what is displayed by the TV.
To avoid confusion, please use the decimal form if you are using the virtual channel number, and add the callsign for confirmation. In the case of WNCF ABC, the real RF channel number is 31, but the virtual displayed channel number is 32.1 (or 32-1).
?1.when combining two antennas must they be they be exactly the same.
It depends upon the application. If you are combining two antennas for additional gain, they must be identical, aimed in the same direction, and have identical length feedlines to the combiner.
If they are not aimed in the same direction, they don't have to be identical, and the feedlines don't have to be the same length.
?2.like can I leave the attic antenna tuned to the majority of stations then connect behind TV the secondary antenna (the $5 flat) aimed at the problem channel 8WAKA?
Try it and see what happens.
Like I’m dreading the attic theres not much headroom and some a$$hole knocked (to long) roof shingles nails though the wood of roof.
Always try the easy way first, before the difficult way. Most roofers don't care if the nails are long enough to hurt you. The labor cost would double if they had to correct that.
I don’t think I need the most powerfull antenna (giant jumbo sized 50’ in the air type because I’m relatively close to TV stations.
That is correct, but your signals will be weaker than indicated on your report because of the indoor location of your antenna and the trees in the signal paths.
As far as reflecters I’ve tried a piece of cardboard covered w/ silver Reynolds wrap also tried a oven grill tray zero improvement actually degraded signal, so no reflector as of now.
A reflector should improve the signal IF the antenna is aimed at the transmitter. Without a reflector, the antenna has less gain and is bi-directional (front and back)
edit: channels watched are 8,12,20,32 and think the antenna is aimed east will verify this.
East is not the correct direction for those channels.
There will be some channel changes because of UHF Repack by the FCC. When the channel changes you will need to rescan.
Most of the changes will be during Repack Phase 5, except for WSFA in Phase 10.
