About arresters: They work quite well for secondary lightning discharges or strong electrostatic charges, that are build up shortly before lightning strikes*. During this effects of thunderstorms you can sometimes already smell the ozon, but you don't get the full hit. If you catch a full hit (primary lightning discharge) they are useless as all equipment between lightning entry poitn and ground/erth gets fried. I've some experience with satellite equipment and terestrial TV and lightning causing electronic toast.
* The flash-channel starts building up, but the channel building up from your antenna isn't the one that does ignite through.
Kenny, I hope that it is just a drowned Coax connection.
