its best to run a heavy gauge (like bigger than 8 ga.) solid copper wire down the mast to the ground rod. attatch this wire to the U-bolts that hold the antenna to the mast if possible. the reason is that masts have multiple sections that are only "physically" connected. that could be a high resistance point and impede the path to the ground rod. multiple ground rods are also a good idea. matt |

Probably the best would be to ground from antenna brackets to ground-rod with heavy gage wire or copper strap. Most masts are painted or if using multiple pieces of mast they are not making good connection with each other. |

Spiderleggs, YES, ALL ANTENNA'S. On ALL my Antenna's, Beams and IMAX and 2/6 Meter I have all mast pipe's Bolted together along with the Antenna's grounded to the mast pipe's and the mast pipe's grounded to the tower's and all 3 legs of the tower's grounded. MAKE SURE EVERYTHING IS GROUNDED! Hope this help's, Lon Tech808 CEF808 N9CEF CVC#2 |
