I need to see a picture, but fyi some of components of an antenna are "electrically" disconnected, but still play a role, wave guides being one example.
Also note, if you are just receiving signals you have more freedom to experiment. Antenna tuning matters a lot more when transmitting (especially at larger powers). (Not implying that it doesn't matter with reception)
- hippich 2y agoJust to clarify - I changed transmitters antenna.
- aeonik 2y agoI'm pretty curious if you could sketch something up. Sounds like you might have inadvertently created a wave guide. If you are feeling adventurous you might want to try dropping your creation into an Antenna Simulation software like NEC or something similar. https://www.xnec2c.org/ https://www.xnec2c.org/

Transmitter is sitting on a pretty tall pole right now and getting it off is a bit of a hassle. And I also already covered cap with a glued heatshrink to protect against elements, so accurate measurements are not possible without destroying it... But I hope it can give an idea what I came up with. Thanks for the link to the simulation tool!
