<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,
Something else is amiss here.
