I know everyone must be really tired of questions about grounding, but I'll blunder forth and ask anyway... One of my towers took a direct lightning hit recently and I did NOT have adequate protectio
Don't you have your metallic guy wires broken up into smaller lengths to avoid rf resonances and the resultant distortion of your directional hf antennas. People normally do that. That being the case
Just to clarify... Are you grounding the guy wires to protect the tower ? My understanding is that we ground the guy wires before the anchor to protect the concrete from taking a lightning hit. I use
One thought I just had, are insulators in this normally in a t-storm wet and simply spark gaps? Would they not flashover in a direct strike? If so, it would seem that whether they are insulated or no
My guy insulators flash over whenever a thunderstorm is within a few miles, well before the thunderstorm arrives. It makes an awesome light show. My four 200 foot towers on highly exposed terrain sur
Can we ask how you grounded your towers/guy wires/feedlines? Tom - VE3CX _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTa
Tom, Each tower has at least one 8 foot ground rod, and the tower foundations are also Ufer grounds. All guy anchors use eight foot galvanized steel rods directly in contact with the Earth. I do not

No. The tower will be grounded by a copper straps, one from each leg, running out at least 50 feet (probably closer to 75 feet) with 8 foot ground rods spaced every 16 feet along them. As I understan

Yes and no. In my case the insulators breaking up the wires are more to allow shunt feeding the tower for low bands. But lightning will most likely ignore a few paltry 2 or 3 inch gaps at the insulat
Yes, as long as those sections are not close to a quarter wave at any frequency where you will be loading the tower. Jim K9YC _______________________________________________ _________________________
