This is Bill from Force 12.
Had a customer ask about making a vertical antenna look nicer. Most of us
know that 'mill finish' aluminum tubing - as is typically used in antenna
construction - may have scratches and blemishes, which don't affect
the electrical performance but might have a cosmetic impact when viewed up
close.
Power coating looks great but is not inexpensive. Spray painting works fine
at HF frequencies if one is careful to mask the overlapping conductors
before painting. Are there other viable options short of painting to treat
the aluminum tubes?
