Precisely, Peter! There was no DC path to ground on my inverted-L, because the tuner at the base was just two or three capacitors.
A spark gap across the resistor will also discharge surge voltages from nearby lightning strikes. The tips of my homebrew shunt spark gap melted more than once from that. And that's why I use Ohmite Type OY resistors for that. 73, Mike www.w0btu.com On Sat, Dec 22, 2018, 10:55 AM Peter Bertini <[email protected]> wrote: > A drain resistor would be advisable if there is no DC return path to > earth... if there is no inductor or resistance between the antenna and > earth it can develop wind or snow induced static voltage buildup, which can > lead to discharges that will cause noise in the receiver.
