Default Hf Antenna Question - so what's the conclusion?

Agreed.


Hi Ian,

Really? 3 to 30 MHz is more than three octaves:
3 - 6 - 12 - 24 + 1/3 octave more

Are we talking about Ham Bands?
160 - 80 - 40 - 20 - 10

Are we restricting from the top of the 80M band through 10M?
4 - 8 - 16 - 32 (actually 88% octave more)

From 60M up?
60 - 30 - 15 + 75% octave more

A subset of HF? such as
160 - 80 - 40
80 - 40 - 20
40 - 20 - 10

To anyone,

Just where did the ARRL come up with this new band plan for HF?

Hi Myron,

Can you see any conclusion yet? Even with the new 3 Octave
specification you still have to pick your application from 3 choices.
