[TowerTalk] Dielectrically lenghtening the boom

[David J. Sourdis - HK1A]

Maybe it has already been applied to the cellphone technology or elsewhere, or it is just not feasible because dielectric losses...

Dielectric material, lossy in some extent, sets a velocity factor (VF) for wave propagation in cables.

This makes the physical lenght of the line shorter than freespace size.

Take a Yagi, and fill the space between elements with a material which its dielectric constant is less than 1.0 (air's). 

Would the element spacing, hence the boom lenght, have to be adjusted by a shortening factor equal to the VF?
