868MHz wire whip, close to battery?
« on: April 01, 2016, 04:46:40 PM »
I have a design that has two sets of twin C cells (i.e. 4 in total). The antenna is internal to the box, basically an 81mm piece of wire, but this has to be about 20mm away from a battery for about half its length. Does anyone have an idea of how much this will affect the range compared to one that isn't? Is 20mm close enough to cause significant issues?

Thanks!
Mark.
