Does that mean you're dissing something just because it's in the ARRL publications?
The laws of physics and electricity exist for a reason. They are indeed a part of the "real world." They are not suspended for amateur radio operators. To believe otherwise is Tool-Time Logic.
Though there are some things that by all that is holy in physics and electronics, should not work, but apparently do. To some degree or another.
That does not mean they work well. That does not mean they should be recommended. Indeed, their use may cause far more problems than are immediately apparent; things like harmonic radiation, various and sundry forms of RFI, damage to equipment, etc etc.
The ARRL Handbooks present basic information; the engineering principles behind the information are pretty sound. Some of their projects are a little far fetched unless one has (a) lots of money, (b) access to a machine shop, or (c) more acreage than most people can dream of... many of the antennas presented in "Low Band DXing" are an excellent example of (c). But, the principles of their design are sound. A knowledgeable ham should be able to learn from these principles and ideas and adapt them to a given situation; but the laws of physics and electricity still apply.
If you're biased (irrationally?) against the ARRL, I invite your attention once again to the RSGB publication, "HF Antennas for All Locations," by Les Monson. This is one of the best "real world" antenna handbooks. It has a fine balance between theory/math and practical advice.
Sure there could have been "more" included in my posts; but I was trying to simplify a very complex subject; and yes, I'm quite well qualified to comment on it, having worked for years in broadcasting, avionics, and public safety radio.
I could make a comment about how ignorance can be fixed, but....
Knowledge is power, people. Read; research; experiment; and LEARN from all these.
I've said all I'm going to say about this.
