Has anyone noticed the resonant frequency of their Force-12
2 element 40m beams shifting under rainy conditions???
I noticed that the SWR dip shifted from 7.120 (dry) to
7.050 (wet) during CQWW.
There also seemed to be a similar shift on the EF-515
15 meter beam that is about 14 ft above the 420/240.
Is this expected?????
