Topband: Bev wire under a path?

[Neil G0JHC]

I currently have  a 585ft Bev, which at around   200ft   has to pass over a
gravel track which is 12-15ft wide. Currently I have installed 2 poles
either side of the path. These poles are 20ft high (so a horse box can pass
under). I have had to guy the poles due to strong winds here by the sea.
They look unsightly and draw attention to the Bev. 

The Bev is 6 to 8ft in height apart from this  section which slopes up  and
down from the poles to cross the road at a height of 20ft for 15ft.the slope
is gradual on either side of the poles until it returns to 6-8ft.

The Bev seems to work fine.

 

I am contemplating doing away with the poles and burying the wire  2 or 3 "
under the gravel track. I am using WD1-a  wire.

 

Has anyone any experience of the effect on performance. I will be burying
approx. 2-3% of its total length.

 

Thanks for your comments and experiences.
