Topband: soldering radials

[Jorge Diez - CX6VM]

Hello,

 

a friend told me to not solder radials to the vertical ring/plate and
between them if I am installing an array, like a 4 square. That´s because
can catch some noise.

 

That´s true?

 

If yes, how can I solder them? Also if I use a DXE plate to atacch the
radials, I need to solder the wire to terminals, so what type of solder may
I use?

 

Do you have a type/model (or ebay link) to see what to use?

 

Thanks,

Jorge
