[TowerTalk] 40-2CD problem

The Cushcraft 40-2CD has no traps, just small loading coils, which should be 
easy to test with an ohm meter if you take the antenna back down.  An open 
coil on the driven element will cause a very high SWR.

Hello,



I am reinstalling my 40-2CD.



He was not working, so I take it down. Seems a thunder trike hit it, because
the coaxial was burn in the top. I replace balun (I replaced balun and
coaxial to be sure the problem is not here, put it up, but still with high
SWR in all the band.



Maybe a problem in the traps?  Looking them seems not to be a problem.  Is
there any way to check the traps to know if someone have a problem?



Any suggestion how can I check it?



Thanks in advance!!
