Not much. They are only a fraction of a mil thick and good insulators stand a few hundred volts per mil so long as there's no sharp points against the latex. Latex isn't that great and its terribly p

Most of the R of a decent antenna is radiation resistance, not wire loss resistance. You can't tell about an antenna's efficiency or looses by looking at the feed impedance. Unless its a very well do

Technically, there are standing wave ratios everywhere in any feed line. Sometimes the SWR is low (1:1) when the load matches the characteristic impedance of the line or is high when the load does no
