Ground Rod at the base of the Top-Rail with short heavy Ground Strap directly to the Top-Rail. The whole piece of Top Rail is Grounded. # 6 - Fifty to 100 Feet of Coax Cable feed-in-line connected from the Matching Transformer to the Radio / Receiver. about as simple and basic as it gets - iane ~ RHF {pomkia} |

It's a Work-in-Progress with two false starts {Whoops} The 1/4" Copper Pipe ~ 15 Feet Long Antenna Element comes from a Icemaker Water Supply Installation Kit http://frigidaire.stores.yahoo.net/unicemakinki1.html http://www.lowes.com/lowes/lkn?actio...=53757-131-813 Ten Foot Piece of PVC Pipe Upper-Mast [ Antenna Element Shape Support ] Attempting to get a 6" Radius Top And Bottom RF Junkie 9:1 SWL-1 Long-Wire Feeder [ Matching Transformer ] with So-239 to "F" Adapter RG-6 Quad-Shield Coax Cable feed-in-line 50~100 Feet. 21-Foot piece of Top-Rail for the Bottom Mast [ Free-Standing with a Ground Anchor ] The Fold-Up and repeated problem so far has been 'forming' the 1/4" Copper Tubing Antrenna Element with the Straight Parallel Runs and the Six-Inch Radius at the Top and Bottom. A Plastic Chop-Stick is being used to Fill the 3" Gap between the Two Ends of the the "C" and hold them in 'fixed' Alignment with the other parallel run. Still have not figured-out whether to use the Top-End of the "C" Gap or the Bottom-End as the Feed-Point. ? Any Suggestions as to Which and Why ? yes - i like play with antenna projects - iane ~ RHF {pomkia} |
