# Calculating SWR for a dipole

I have a dipole wire antenna that is tuned to 14.0 MHz so that it has an SWR there of nearly 1:1. Is there a mathematical formula by which I can compute the expected SWR for other frequencies? I would, for example, like to calculate the expected SWR if I transmit a frequency of 14.3 MHz into that same antenna.
