Default Will covering an antenna with tape negate its effects?

i was surprised to find that the black plastic spiral cable wrap that i
was using as abrasion protection for a cb antenna shot my swr all to
hell! its heavy vinyl plastic but i thought that it would be rf
transparent! who can explain this? as far as the thin scotch tape goes
i dont think there will be any effect. especially for receiving where
the antenna is not tuned precisely on frequency. however the tape WILL
rapidly fail due to uv from the sun. i presume that you are using clear
packing tape for shipping boxes? its strong stuff but NO good against
uv. how about foil tape used in alarm systems as the element and
fastening system combined? it will stay on a smooth surface for years
and years!
