[bars] Radials

[KC1SOZ]

Interesting. After some research i found that the radials the factory sends
are 10" long.

Since i will have to roof mount the antenna (my property apparently sits on
a huge granite boulder), i am trying to keep the experimentation down to a
minimum, for obvious reasons. That's why I am looking for other HAM's
experiences with it. Thanks!
