一个很小和天线计算程序

    I've read and re-read the meter to frequency designators.  You
know, 2m is 150 Mhz but we use 144-148 MHz.  So just for fun let's see
what the actual math says.

    Designators         Freq range        Real Lengths       Des-freq
    ==================================================================
   160m band          1.8-2.0 MHz        166.67-150.0m        1.875MHz 
    80m band          3.5-4.0 MHz          85.7-75.0m         3.750MHz
    40m band          7.0-7.3 MHz         42.86-41.1m         7.500MHz
    30m band         10.1-10.15 MHz        29.7-29.56m       10.000MHz
    20m band         14.0-14.35 MHz       21.43-20.91m       15.000MHz
    17m band       18.068-18.168 MHz       16.6-16.51m       17.647MHz
    15m band         21.0-21.45 MHz       14.29-13.99m       20.000MHz
    12m band        24.89-24.99 MHz       12.05-12.0m        25.000MHz
    10m band         28.0-29.7 MHz        10.71-10.1m        30.000MHz
     6m band           50-54 MHz            6.0-5.56m        50.000MHz
     2m band          144-148 MHz          2.08-2.03m       150.000MHz
  1.25m band          222-225 MHz          1.35-1.33m       240.000MHz
   70cm band          420-450 MHz         71.43-66.67cm     428.571MHz
   33cm band          902-928 MHz         33.26-32.33cm     909.090MHz
   23cm band         1240-1300 MHz        24.19-23.08cm    1304.348MHz

   The bands outside their designators are 40m,30m,20m,17m,15m,12m,10m,
2m,1.25m, & 23cm.

    Maybe the designators should be:

    160m, 80m, 42m, 30m, 21m, 16.5m, 14m, 12m, 10.5m, 6m, 2m, 1.35m,
    70cm & 67cm, 33cm, & 24cm  


Just a thought, ;-)
