G6HKS Wet Weather Test 2015

Wet weather performance at G6HKS during a very heavy rain storm!

Richard Mason G6HKS recently constructed two G4CQM designs, WAXXX10S (144MHz) and four CQM18UC (432MHz) yagis. During extreme wet weather experienced over the past few days Richard decided to look at the forward and reflected power using his Bird 43. Images seen below show the result. Richard also remarked that both yagi types did not suffer any audible quieting on receive during the rain storm. This happens when yagis go off tune during periods of instability!
