To test the repaired traps
last night removed the 4 element 10m beam partly
and placed the 40 20 extention trap 1 repaired 1 original
only radiator  and 1 director left as counter weight stil the antenna  is strong directive 
the director does work

the 40-20 trap extensions  left is with PTFE-glasfibre reinforced tubes
the coils are Aluminium 1.5mm   right is original
The isolator  original is a type of hard PE tube 27x21.5 it is special harder then HD-PE
The rings are separate made. This VS-2440 beam is constructed as light as possible
But the melting point of PE  is rather low. And the traps can heat up  I estimate about 10% loss.
No matter how well constructed they are. The antenna  performed nice but never thought that the 40 20m trap would have that much loss.  


the 40/20m extention trap complete with top-load tube  weight only 660g original PE   
with PTFE 713g.  The first test showed the tuning for 20 and 40 is 100-150kHz to high
hopefully I can tune it into the CW part of band.
