Too much antenna voodoo now, Jay.

I'd ask Jay if he thinks it helps, he's sorta our resident antenna guru in this group so far. Ask him about his credentials first tho. Too much antenna voodoo now, Jay.

At the correct length? You can't cheat a ground plane reflector with a coil, can you? |

I just re-read that and that's not what I meant to say, sorta. By antenna
voodoo I mean advertised gain factors, which seem to get more outrageous every year. Your reflector idea makes sense as long as the mast can handle the wind load, it would reflect more. I have to say your ground plane is the best I've seen. Do you still sell them? Steveo wrote: Too much antenna voodoo now, Jay. Your walkin' papers are still impressive imho.

The addition of the ground plane kit in theory would lower the angle of
radiation by a certain percentage. This gives the impression of gain. If your in a flat open area in Kanas someplace or are a avid DX'er, this may give you a very slight boost. But if you don't fall into those 2 areas mentioned above, save the cash. |

Then the feedline is no longer part of the antenna system and does not alter antenna tuning. james |

Forget about the ground plane kit, and put that antenna as high as you can get it. Antenna height trumps all. That's right! Any bulky decoupling radials on that antenna are just a waste of effort due to its basic flatter radiation pattern. Give the coax drop a couple wraps around the mast on the way down to act as a slight choke for decoupling purposes. No one has mentioned the extra wind load that add on radial kit carries. Don't waste your money on it op. Spend it on grounding instead. |
