I don't have wax paper, but I don't want to ruin the chocolate-dipped pineapple I'm making tomorrowWill it dry ok on a regular plate or aluminum foil?
you need to strip the insulation where the elements connect to each other and to the coax cable.
No you do not need to strip the insulation from the wireIf you do, it will make very little differenceThe copper will oxidise, but it can be readily proven - and demonstrated - that that oxidisation will have a very minimal effect on the 'skin resistance' (despite what is commonly believed)I assume your Yagi has one reflector, one driven element and three directorsAs far as getting that antenna to work as it should, you need to consider the spacings between each driven element and the spacing between the driven element and the reflector and the spacing between the driven element and the first director: these spacings can be critical and will determine the feed-point impedance of that antennaYou also need to consider the type of driven element you have: it is a folded on non-folded element? That also has a large influence on the feed-point impedanceFinally, since this is a balanced antenna, you should feed it with balanced cable, or co-ax via an unbalance - to balance transforming deviceThere is plenty of info.on the 'Net to cover all of that, so I needn't say any more.
Foil will work without spray on the dull side of the foil, not the shiny sideI've been in a bind and it worked for my chocolate covered strawberriesAlso when setting, make sure they are not sitting in direct light as in kitchen lighting, as iit tends to slow the chocolate setting process.
