Topband: Slinky vs. Loading

[Tom Rauch]

> The third option was to load the short beverage to make it
electrically
> 1-wavelength long. Since I wanted to verify the
> proper loading coil values and because the lowest
frequency that my Autek
> RF-1 will tune to is about 1130khz, I initially
> constructed the short beverage as two shortened, loaded
dipoles, each
> having two loading coils (each about 71 microH)

> However, this antenna does NOT work well on 80 or 40. It
appears that the
> loading coils act less like loading coils and
> more like RF chokes at these higher frequencies.
