[amsat-bb] True bearings vs. magnetic

[jim at k6ccc.org]

Your example is a 3 element CB beam.  That is a FAR cry from even the smallest yagis that are routinely used for VHF & UHF satellite operating.  Personally, I run 22 elements on 2M and 40 elements on 430.  Back on AO-40 on 2.4 GHz, I was running a 2 x 3 foot dish.  I can guarantee you that with high performance antennas, the difference between magnetic and true heading would make a large difference.

The VHF and UHF antennas (photo taken before the dish was added):

And one after the dish was added:

And yes, before someone points it out, it's been years since I was active.  Several reasons for that. One of these days, I will be back...

I don't think its all that critical based on what I see here:
