S* In regards to radiating RF energy, the only difference insulation makes is the elements are slightly shorter due to the change in velocity factor. Insulation makes an antenna heavier, can reduce corrosion, and can allow you to have whatever color antenna you want. So define "better". If you mean work as an antenna, there is no difference. You are a babbling idiot. -- Jim Pennino Remove .spam.sux to reply. |
