|I've got the bug to get back on HF. I have a 14AVQ vertical that I last used 25 years ago, but when I ground mounted it and connected my antenna analyzer to it, the SWR in all 4 bands was very high. I found that the base inductor was open. I attempted to open the base and repair the coil, but it's not repairable. Now I'd like to wind a replacement inductor and connect it between the mounting bracket and the bottom of the mast. Will I have to determine the size of the inductor by trial and error, or does somebody have an idea of how much inductance I'd need. If so, would you have any idea on the dimensions and how many turns I'd need to make it?
