After reading multiple threads and seeing the issues and lack of customer support for the Artex 345, I ordered the ACK E-04, 406 ELT for my RV6 from Gulf Coast. They have a good policy of price matching so it only set me back $489.
I brought up the issue of inadvertent activation due to static build up. They had not heard of the problem so Casey at Gulf Coast opened an ELT box but could not find a suppressor. He then got on the phone with ACK. Turns out ACK knows of the issue and all new units ship with a BNC inline suppressor. Hope this solves the problem.
Kudos to Gulf Coast and ACK for addressing this issue.
