First post here yay!
I am repairing Shengda sdhf dual band antenna (looks similar to a Comet x50) it showed a SWR of >3 on both UHF and VHF. I opened it up and the only connection I could see from the centre core to the antenna element is two caps. I'm pretty sure they are broken.
They are not marked though and the electronic store clerk couldn't help me either. They do have colours marked on the tip but it doesn't agree with any of my textbook identification charts. Any help would be appreciated.
