I live in a place that has a Declination of approximately plus16 degrees. I am putting my tower in soon, so I want to do it right. I have asked several hams and one says "just use magnetnetic" the ot
It depends on the beam. A 2 or 3 element HF antenna has a 3db beamwidth of, what, 60, 90 degrees or more (too lazy to look it up)? Certainly not < the 16 degrees that you would be concerned with. Al
Most surveys in the last few years should be correct. Have you tried shooting a magnetic azimuth down a lot line to see if it is different by about 16 degrees? Chuck W5PR ____________________________
Chris, Go to this website https://gml.noaa.gov/grad/solcalc/ and drag the large pin to your QTH. Determine your Solar Noon from the results table. If you place a stick in the ground at your prospecti
Why would the tower care? I want to do it right . If I am turning my beamChile, I don't want to actually be shooting at the ocean. Any advice please _______________________________________________ __
If you want to know what direction your beams are pointed, true north is the answer. "Magnetic north" doesn't affect the direction to point your antennas if your goals is to point them directly at t
At night you can look for the Polaris star, also known as the North star. It will be above the horizon at the same degree of latitude as your QTH. It is quite bright so it should be easy enough to fi

That was my thought. What happens with a tubular tower.........OMG. It doesn't matter where the faces of the tower point. You calibrate the rotor the antenna. W0MU On 4/28/2022 3:49 PM, Chris Hoel
Chris, I'm up the coast from you. Lot lines in this state are on a true N. Just line up with that. Close enough works. Doubtful that the receiving end of your signal or your signal reception will lik
I would not worry about the tower but I would determine true north when mounting a beam, not that 16 degrees will make much difference to an HF Yagi Ken WA8JXM _______________________________________
Ken WA8JXM Is it time to mention that of course the owl faces north, and that's what you should use as a reference. BTW, I'd use true north as zero degree reference. Declination is always changing.
And occasionally the magnetic poles flip. John KK9A BTW, I'd use true north as zero degree reference. Declination is always changing. _______________________________________________ _________________
