Hi Frank/Arie

Not really knowing what I was doing grin I tried EK and got the same bad
average gain figure.. I also removed most of the lower part of the mast
since its effect will be fairly minimal. No help there either.

Tnxs for your comments gents. There is still the two questions though;

- Does one bother to model in a "curved" wire for copper pipe joiners? I
note Mr Cebik didnt mention it when he was talking about J poles on 2m.

- Is the diameter of the source wire important?

Thinking now about reducing the copper pipe diameter simply so I can model
it properly. Then again its a pretty broad design and tuning would be
easy...

Hi Bob, attempting to model a curved wire will possibly lead to
over-segmentation. It is also important to avoid junctions of dissimilar
wire diameters as it can lead to errors. The source wire should therefore
be the same diameter as the rest of the structure.
