I have a 2 meter yagi I want to mount vertically on a tower.
I read I need to use a non-metallic (fibre-glass) mast, but how much separation should there be between the tip of the radiator and the tower?. I have read on the internet, 1/2 wave, full wave, and it doesn't matter.
Couldn't find the answer in the Amateur Radio Handbook.

Thanks,
Dave K4DJW

Common consensus is half wave separation, though we recently modelled this with Eznec and the performance isn't too different at 1/4 wave if you can't manage 1/2 wave.
