Hi Robert,
see the right picture, that is what i mean.
"Next I started to examine the antenna, I noticed that inside the flap was not making contact with the coil, looking at pics from dx patrol manual I saw their one was, so I bent the flap so that it makes contact but still high swr."
tnx Detlev, DC7KG

Hello together,
i see a serious mistake in picture #1. The copper flag represents a capacitor and must not touch the helix! It is like a short circuit, that is not correct. Recalibrating without measurement option should be difficult.
The soldered cable is definitely not working 13cm RF.
Good luck with the repair.

Hello together,
I built a bandpass filter based on UKW-Berichte 2/77. Can also be produced without a lathe with a standard aluminum profile. The insertion loss and the filter curve can be found in the appendix. My son Benedikt, DO4DY, is currently using it to suppress the fourth harmonic on his portable station. The fourth harmonic is suppressed over 60dB.
