[Boatanchors] Good (And Bad) Lengths For End-Fed And Dipole Antennas

[Rob Atkinson]

Thanks for taking the time to post this data.

>BAD:  16  19  22  26  32  33  38  44  46  48  52  64  65 66  76  78
>80  88  92  95  96  99  104  110  112  114  123  128  130 132
>133  138  144  152  154  156  160  165  171  176  182  184

I guess I don't understand what this means.  If I am correct it tells
me that a 80 m. half wave dipole fed in the center with each side 65
feet long is "bad."   That's a 1/2 wave dipole 130 feet long which
according to the ancient forumula is cut for 3600 kc.   That's exactly
what I have, fed with ladder line and a KW Matchbox and it works FB.
 The numbers list says 130, 128 and 132 feet are bad.  Does this mean
131 feet is okay?  That seems ridiculous.  So I must not understand
this.
