Default The catenary effect

...

For a 1m sag the vertical component is below -60dB and it's close to the
unsagging performance.

I was interested in the catenary problem for a different reason.

I toyed with the idea of making one of those at one time.

I have seen designs like that before. I always wondered if they really
worked out when carried out to the extream like the 100 foot long boom yagi
in that pix.

I would think that in real life things would fall off more than the model
would indicate, but maybe not.
