<I think the antenna is a big capacitor formed by the antenna as one of
capacitor?s plate ,the big tower plus antenna clamps are the other
capacitor?s plate,this gives a lot of capacitance that is changing the
antenna?s frequency of resonance,it is better to separate the dipole from
the tower which now is  only 1 inch.
  Insulated plate and clamps are a must!

## I find this hard to believe.  If there is any stray C  between  each ele half, and the al
plate he has it mounted to,  you could easily measure it with any digital  LCR meter. 

##  F-12  mounted their 40m and 80m rotary dipoles to large  17 inches wide x 8 inches tall
al plates , using just split  PVC tube u find in any home depot electrical dept, the  grey  stuff, 
UV resistant.  

Something else is amiss here.
