Hello,
Well, in theory that should be a bit stronger, though I doubt you anyone will notice ...it is not going to be "a large practical difference".
A lot of guessing....( i dont like to guess)
Im guessing they have used something in the 6083 ..6082 aluminium, leaning to 6083T8...
I remember some of the CTE antennas were not "shinny" they had a "anti corrosive" coating on it.
(probarbly just what was availible).
These coils are used in many antennas (GPE)
I have several lying around in my junkbox.
A couple hundred watts in FM and maybe 500..in SSB, and you should be "save".
It does depend on factors like "temperature", time , wind etc.
Those coils have a "protection" layer around it...often moist is problem ...
It isnt an antenna which is known to be reliable for many years.
Kind regards, Henry 19DX348
