Default Stupid question on twin feedline (air)

Hello Jawod,

I have buit a twin leed for my center feeder dipole with PCV tubes:

Tubes are after filled with glue. You can see here the final result (click
on the picture to enlarge it):

Spacing is 5 cm
Distance between spacers is 60 cm

It has been installed for 3 years. It has resisted to many strong winds.

Good luck

Regards

...
I will assume that balanced (air) feedline is homebrew. What
recommendations are there for spacing between the twin lines? Number of
spacers per foot? If homebrew, how to keep spacers from migrating...will
small wire "stays" modify feedline characteristics?

This is all about feedline to simple dipole or inverted V.

Thanks,

a new (old) ham
