Thanks, this makes more sense! By the way if some of you are interested here are some results:
- Ezuhf receiver "sander" stock monopole - very bad VSWR > 3 far away from 433 mhz
- Ezuhf transmitter rubber whip stock monopole - very bad VSWR > 4 far away wrom 433 mhz
- Diamond SRH771 - perfect match for 433 mhz with VSWR<1.1 -/narrow band/
- Several dipoles and one moxon from the IB Crazy tutorials - 310 mm is not perfect for 433 mhz -
it seems a litle short, but seems close. I will try start cutting it from 330 mm next time. VSWR<1.5.
I can make some videos these days. If you want me to test some particular antenna tell me. My metter can go up to 3 ghz.
