Subject: Coax breakin?
I will be erecting a new antenna system soon for HF operation.
However, I noticed an April 1997 article in QST that mentioned coax
feed-ins should be 'broken in'. The author advised to DC current
harden the center conductor and sweep varing AC signals. Also, he
mentioned that one should pull or tension the cable, so as to reduce
mechanical resonances.
To those Nasa engineers or other experts, is this really necessary
(supposely reduces back ground noise)?
