Sorry to hear about what happened.

I really never knew powerlines could interfere with your signal. We have a powerline running right through our field on the farm - have never had any problems regarding signal loss or similiar due to it. We had signal loss one time - but that was due to a non-charged battery pack in the plane. Also there is one club which I have been to which is right by huge powerline structures. Really is a first of me hearing about this. Good to know.
