Topband: phased array question

[Ron Spencer]

Using a Comtek box I phase 2 shunt fed towers. Was tuned centered on 1830.
We have had a LOT of rain to the point the ground is saturated. For the
Stew it appears the resonant center point for the array has moved down to
around 1815.

I'm not certain what that is indicating. My guess is a need for more
radials for one or both towers. Am I right?

Thanks   Ron   N4XD
