Trying to see what makes an antenna work.
I was given this antenna but it had a high SWR. I replaced the screw on section on the bottom where the coax connector goes on as it was bad but still has a bad SWR.
Cutting windows into the sides until I found the workings that was causing a short from the ground to the top where the whip screwed in. Here is some pics of the mess. The resistor, I can't see
colors too good, and not sure of the cap size.
Can you tell what the size of the cap is? It reads .38n on the 200n selector on the multi meter. Is it electrolytic or mylar? Can I replace with any cap? This resistor read .8 ohms with my meter. Don't think this is right. Maybe you can see better than me. Colors look like gray gray blue gray wide silver or gray. I know if I replace the cap and resistor it will work! This is an old BIG STICK. I do have another big stick that works. Ron
