resonant |ˈrezənənt|

adjective

(of sound) deep, clear, and continuing to sound or ring : 

verb resonare, from re- (expressing intensive force) + sonare ‘to sound.’

You need to define what you mean by "ring".

The antenna will see a conjugate match at 1.85MHz (not 2.24MHz) looking back 
towards the station end, but I don't know if that's what you mean by "ring"?
